The gold standard diagnostic procedure is sinus aspiration and culture discount rulide 150mg, although there is rarely a role for this painful and invasive technique discount 150 mg rulide free shipping. Treatment Treatment of acute sinusitis depends primarily on the etiology of the disease generic rulide 150mg free shipping. Treatment options include medications that decrease the general symptoms, such as decongestants and nasal saline, as well as those that treat a specific cause, such as antihistamines in allergic disease or antibiotics in acute bacterial sinusitis. If acute bacterial sinusitis is diagnosed based on the criteria discussed above, antibiotics are recommended for adults and children to achieve more rapid clinical improvement and cure. Randomized, double-blinded, placebo-controlled trials have been performed in adults and children comparing antibiotic treatment with placebo in subjects with clinical and radiographic diagnoses of acute bacterial sinusitis. These trials consistently have shown that there is a small but statistically significant decrease in symptoms at 10 to 14 days after starting treatment with antibiotics versus placebo. It should be noted, however, that most subjects receiving placebo recovered without antibiotics. The goal of treatment is to decrease symp- toms, prevent serious complications and sequelae such as osteomyelitis or orbital abscess, and prevent permanent mucosal damage. Therefore, treatment of suspected acute bacterial sinusitis should include antibiotics if symptoms are moderate to severe or if symptoms persist despite symptomatic treatment. Antibiotic choice depends on the age of the patient and the presence or absence of risk factors for antibiotic resistance. All antibiotics have been shown to be approximately equally effective in clinical trials, with all those listed below dem- onstrating resolution of symptoms in more than 85% of subjects. Further studies have shown that narrow-spectrum agents, such as amoxicillin, are as effective as newer, broad-spectrum agents are as a first-line treatment. Although amoxicillin has only partial coverage of Haemophilus influenzae, it is a reasonable first-line agent because many infections caused by organisms with in vitro resistance still will improve with treatment. Erythromycin, tetracycline, and second- generation cephalosporins with less activity against H. First-line agents are used in individuals with no recent antibiotic use or other risk factors for increased likelihood of antibiotic resistance. The American Academy of Pediatrics and the Clinical Advisory Committee on Pediatric and Adult Sinusitis recommend similar algorithms for choosing antibiotics (Table 6. Duration The optimal duration of therapy has not been determined through systematic con- trolled trials, but most clinical trials use a course of antibiotics lasting 10 to 14 days. The results of some trials of shorter courses of antibiotics are promising, but more data is needed before shorter courses become routinely accepted. Another proposed approach is to treat patients with antibiotics until they become symptom free, then for an additional 7 days. This recommendation strives to balance appropriate mini- mum length of treatment with avoiding prolonged treatment in asymptomatic indi- viduals who are unlikely to be compliant. Other Treatments Other treatments that target symptoms can be used for viral or bacterial sinusitis. Because most upper respiratory infections will resolve without antibiotics, these ancillary medications are the mainstay of treatment for most cases of acute sinusi- tis. Oral decongestants are likely to be helpful in relieving symptoms and can be Table 6. Care should be taken in patients with glaucoma, ischemic heart disease, and benign prostatic hypertrophy, but decongestants generally do not raise blood pressure substantially in individuals with stable hypertension. Topical decongestants may also help to relieve symptoms in adult patients, but the reduction in mucosal blood flow may increase inflammation, creating more congestion as the medication effects wear off. Topical decongestants should not be used for more than 3 days because of the risk of rebound vasodilation and worsening congestion. One clinical trial compared a combination of a topical decongestant and oral antihistamine to placebo in children with acute presumed bacterial sinusitis; all children in this study also received amoxicillin. Subjects in both groups improved quickly; no differences were noted in clinical or radiographic resolution between the two groups. Nasal Steroids Nasal steroids have received attention for their role in treating the symptoms of acute sinusitis. In a recent study of mometasone, treatment with 200 mg twice daily (double the usual dose) significantly reduced the duration of symptoms compared with amoxicillin alone or placebo. In children, studies have shown a modest benefit on the symptoms of acute sinusitis from nasal steroids as well, particularly during the second week of treatment and beyond. Multiple other treatment options have been proposed, but there is little evidence available in adults or children to evaluate their effectiveness. Antihistamines are effective in treating allergic sinusitis and may help relieve symptoms in a patient with acute sinusitis with predisposing allergic rhinitis, but are not recommended for most cases of acute viral or bacterial sinusitis, because they can dry secretions and inhibit mucus clearance. Topical anticholinergics, such as nasal ipratropium, may help to decrease rhinorrhea, but this treatment has only been evaluated in subjects with viral upper respiratory tract infections and not in acute bacterial sinusitis. Saline nasal sprays have also been shown to reduce rhinorrhea in patients with rhinitis, but have never been studied in acute bacterial sinusitis. There is no evidence that echinacea, vitamin C, zinc salt preparations, or mist help to improve sinusitis symptoms. Summary Acute sinusitis is a common clinical condition in adults and children, with multiple etiologies. The symptoms of acute sinusitis overlap considerably with other upper respiratory conditions. Clark sufficient sensitivity and specificity to be useful in routine clinical practice, acute sinusitis is usually diagnosed clinically based on the constellation of signs and symptoms. The determination of the etiology of the sinusitis is also a clinical decision (Table 6. Once a diagnosis is made and a presumed etiology identified, many treatment options are available, including antihistamines for allergic rhinosinusitis, antibiotics for bacterial sinusitis (Table 6. Narrow-spectrum antibiotics, such as amoxicillin, are recommended as initial treatment in uncomplicated bacterial sinusitis. Most cases of acute sinusitis are uncomplicated and will resolve no matter the treatment. In some cases, however, symptoms do not resolve despite a prolonged course of treatment or they recur several times within a year. In the event of complications such as periorbital cellulitis, intracranial abscess, or meningitis, prompt treatment of the complication and evalu- ation by a specialist is critical.

Using blood plasma as the sample fluid, high-to-moderate abundance proteins covering a 6 order-of- magnitude concentration range have been quantitated without sample pretreatment [3-5]. Moreover, these strategies are limited in their multiplexing capacity (135 peptides targeted in a single method represents one of the largest multiplexed panels quantified to date ) and depth of quantitation (quantitation of sub ng/mL proteins remain a challenge). This study used matched proteomic samples to assess, in a side-by-side manner, the quantitative potential and multiplexing ability of this combination of methods. Scaled-up plasma digests were prepared according to a denaturation/digestion (deoxycholate/trypsin) procedure developed previously in our laboratory . The deoxycholate surfactant was insolubilized through acidification and pelleted through centrifugation. From the optimizations, the top 3 transitions per peptide were chosen regardless of the precursor Medimond. Plasma protein quantitation was determined by either linear regression analysis of 7-point peptide standard curves (for the 1D analyses) or peptide relative response measurements (for the 2D analyses). Prior to quantitative evaluation, a number of preliminary optimizations were performed. In regards to the latter, 348 of the 654 scheduled peptides (corresponding to 151 proteins) passed the screening test in the 1D analyses. Considering the 306 rejected peptides, 62 were removed due to interferences from non-target ions, while 244 failed detection altogether since they were of low abundance. In the 2D analyses, a total of 381 peptides (177 proteins) passed the interference test while 273 were rejected due to interference (121 peptides) or detectability issues (152 peptides). Instituting serial LysC-trypsin digestion enhanced digestion efficiency, but did not improve digestion for the peptide targets of interest. In comparing the two methodologies, a total of 51 peptides (40 proteins) were observed only by the 2D method, while 18 peptides (14 proteins) were detectable only by the 1D method. The result of these preliminary analyses was a list of interference-free peptides from which the quantifier transitions were selected for reproducibility and quantitative assessment. The high reproducibility and sharp chromatographic peaks (average peak width at half height of 5. Nonetheless, the 312 qualified peptides (equates to 142 plasma proteins) demonstrated excellent signal stability (6. The calibration curves for the qualified peptides demonstrated good linearity (average R of 0. The determined concentrations spanned 6 orders of magnitude (31 mg/mL for albumin to 44 ng/mL for myeloblastin) and were inferred from the peptide that generated the highest calculated concentration. This enabled the concentrations of 177 plasma proteins (inferred from 381 peptides), spanning an 8 order-of- magnitude range (31 mg/mL for albumin to 556 pg/mL for matrix metalloproteinase-9, to be determined. Included in this list were 23 low-abundance proteins that were below the concentration limit determined by the 1D analysis. The enhanced sensitivity of the 2D fractionation method enabled tissue leakage products, such as myoglobin (a diagnostic indicator of myocardial infarction), to be quantified. An added advantage of the 2D fractionation method is that it enabled 18 moderate abundance proteins with plasma concentrations above 44 Medimond. A further indication of the reliability of these two methods is that similar plasma protein 2 concentrations were obtained regardless of the method and data analysis strategy used (R of 0. Using the same control, the plasma protein concentrations determined from these new curves were found to be nearly equivalent to those 2 found during method development (discussed above), as evidenced by a R value of 0. To assess for interferences in the diseased samples when a single transition per peptide but multiple peptides per protein are monitored, we prepared peptide relative response plots for all target proteins. Assessing the linearity and examining the deviations with peptide extracted ion chromatograms enabled chemical interferences to be identified. Since only the quantifier transitions are monitored, higher peptide multiplexing can be achieved. The determined concentrations span 6 orders of magnitude (from 31 mg/mL for albumin to 44 ng/mL for myeloblastin), which covers the reported range of high-to-moderate abundance plasma proteins. This enabled 23 additional proteins below and 18 proteins above 44 ng/mL to be quantitated within an 8 order-of-magnitude concentration range (31 mg/mL to 556 pg/mL). Importantly, similar concentrations were found between the methods despite being derived from different samples and different analysis strategies. Although additional development of the 2D method is necessary to improve the quantitative performance, the current version is robust and can already be used to obtain improved sensitivity and high specificity in pre-clinical protein biomarker verification/validation studies. Thorough inspection of the remaining Fifty articles which appeared to be relevant by full-text 7 artclices were meeting our inclusion criteria. And extensive assessment of references yielded two more studies making a total of 9 primary studies that met our inclusion criteria.

In particular generic rulide 150 mg fast delivery, global objectives of any ex situ conservation programme must include the preservation of the adaptive potential of the species order rulide 150 mg with amex, the minimization of the risks of inbreeding depression and the prevention of adaptation to the captive environment rulide 150 mg with mastercard. In order to achieve these aims, captive breeding programmes must be scientifcally managed based on all available genetic and demographic information, with the application of most effective managing strategies. E A primary task of any ex situ programme is to defne the targeted units of conservation. For a species with some degree of intraspecifc structure, it has frst to be decided whether perceived genetic units should be mixed in a single captive population or bred separately. Secondly, it has to be decided the number and origin of the founders, the objective being to capture the highest possible proportion of the genetic diversity still present in the wild, while minimizing the impact of extractions on the wild populations and considering the intrinsic capacity limitations of the Programme. Finally, management strategies need to be applied to minimize the losses of the captured genetic diversity and the accumulation of inbreeding over successive generations. The generalities of genetic issues in ex situ programmes have been thoroughly treated in a separate chapter of this volume (Leus and Lacy, this book). In this chapter we will elaborate on these issues for the particular case of the Iberian lynx. Firstly, we will discuss whether lynx populations should be considered as a single management unit based on the existing knowledge on the genetic and demographic history of the species. Secondly, we will evaluate the genetic status of the captive Iberian lynx population as of mid- 2008. Finally, we will explore alternative strategies and discuss the role that genetic markers may play in the genetic management of this captive population. IdentIfIc atIon o f m a n a g e m e n t u n I t s : t o m I x o R n o t t o m I x In structured populations, a frst important decision is whether the different population segments should be combined and managed as a single unit or managed separately. Mixing is the best option when genetic differentiation arises as a consequence of genetic drift acting independently in recently isolated and declining populations. In this situation mixing would revert the accumulated inbreeding and maximize the potential genetic diversity of the captive stock.

The decision to mix or not to mix is, therefore, largely based on the direct evaluation of the existence of adaptive divergences or on the evaluation of the opportunities for such divergences to have arisen in view of the evolutionary and demographic history of the species. For this purpose, the analysis of genetic patterns for molecular makers might be extremely useful. Although both populations are the consequence of a common process of decline and fragmentation, they have slightly different recent demographic histories. Doana is a peripheral population that became effectively isolated from the rest of the species distribution probably more than fve decades ago, and has remained isolated and at a census size of around ffty since then. Under this demographic history, the action of genetic drift may have resulted in a pattern of low genetic diversity and high inbreeding within populations and high genetic differentiation between them, although the magnitude of these changes is diffcult to predict without precise estimates of demographic parameters over time. The two main findings are that genetic diversity is globally low, but lower in Doana than in Sierra Morena, and that these two populations show a high level of genetic differentiation. Mitochondrial diversity is extremely low in the Iberian lynx, with only two haplotypes observed which differ in one single position. However, 91 our previous study detected the presence of the Doana haplotype in a museum specimen from Sierra Morena, and also showed the occurrence of a third now extinct haplotype in Western Sierra Morena (province of Huelva) (Johnson et al. These results with mitochondrial DnA provide direct evidence for diversity losses in recent times due to drift in the small remnant populations and to the extinction of differentiated populations. Iberian lynx nuclear microsatellite diversity levels are also globally low, both in terms of heterozygosity and allelic diversity. On the contrary, some extreme examples of small isolated populations like the Gir forest lions and the Florida panther (before the successful translocation of pumas from Texas) do seem to harbour lower diversity than the Iberian lynx (Table 1). Interspecific microsatellite diversity comparisons must be interpreted with care because of the possible ascertainment bias, but they actually suggest lower genetic diversity in the Iberian lynx than in closely related populations/species with similar life history. Moreover, microsatellite heterozygosity and allelic diversity are 33% lower in Doana than in Sierra Morena. A high level of genetic differentiation is observed between Doana and Sierra Morena populations, i. As expected from the known demographic history of the species, genetic patterns found in the Iberian lynx population could have been shaped by the predominant action of genetic drift in recent times, according to size and time since isolation of each population. Accordingly, the strong differentiation found between Doana and Sierra Morena populations should be mainly due to random allele frequency fuctuations occurring in each fi G u r e 1. Moreover, low levels of current genetic diversity are probably the consequence of a steep and rapid loss in recent times, especially in Doana, where the loss might have reached over 33% in magnitude. Furthermore, an effective size like that estimated for Doana could retrospectively explain the loss of 33% heterozygosity from an ancestral diversity similar to that currently present in Sierra Morena in less than ten generations (50 years). Under such scenario, diversity losses may be equated to inbreeding accumulation, so that a 33% diversity reduction in Doana would refect a population inbreeding coeffcient for Doana well over that expected for full-sibling matings. Such high inbreeding values are often associated to a high frequency of genetic disorders, low fertility and other negative effects, as illustrated by the notorious case of the Florida panther (Roelke et al. A high incidence of glomerulonefritis and lymphoid depletion has been reported for Iberian lynx (Jimnez et al. Establishing that these and any other observed defciencies and abnormalities in Iberian lynx are due to inbreeding depression or genetic depauperation will not be easy to proof, but this possibility must be seriously considered in view of the observed genetic patterns and the recent demographic history of the species. A recent study reported morphometric differentiation between Iberian lynx populations, but also demonstrated temporal morphological changes within Doana. The potential for dispersal and gene fow in the species is probably high, as in other lynx species, although it has been shown to be strongly affected by habitat matrix (Revilla et al. The anecdotal case of an animal from Doana that made its way back after being liberated in Andjar (Eastern Sierra Morena) illustrates the potential for long distance movements in the species. Such high dispersal rates in the past would 93 have hindered the development of strong adaptive divergences between these two populations. When the points discussed above are considered together, the management of the species as a single unit arises as the most sensible management option. In other words, in view of current genetic patterns and the demographic history of the species, the risks of inbreeding depression largely exceed risks of outbreeding depression in the Iberian lynx. The Iberian Lynx Ex situ Programme is consequently managed as a single mixed population and already harbours several captive-born interpopulational litters (Vargas et al. Moreover, the frst wild progeny of interpopulational crosses were born in Doana in spring 2008 following the release of a single Sierra Morena male, which becomes the frst example of successful translocations of Iberian lynxes. This can only be achieved by maximizing the number of individuals brought into captivity, although in most real-world scenarios this has to be tampered by the need to minimize the impact of extractions from the wild populations.

The domestic cat is seasonally polyestrus in naturally fuctuating photoperiods, but will cycle year round when maintained in 12-14 h of artifcial light per day (Shille et al. Melatonin appears to be the signal by which the female domestic cat measures photoperiod, with ovarian activity ceasing under decreasing photoperiod and resuming with increasing photoperiod (i. Melatonin secretion is controlled by the prevailing photoperiod (as in other mammals) with concentrations being highest during the dark phase (Leyva et al. Exogenous melatonin administered intravenously or orally can suppress ovarian activity in domestic cats maintained under a variety of lighting regimens (Leyva and Stabenfeldt, 1989a, b; Graham et al. Females appear to exhibit a graded response to melatonin, with follicular suppression occuring more rapidly as the daily duration of melatonin elevation is increased (Leyva et al. Reproduction is at least somewhat seasonal in some non-domestic felids like the tiger (Seal et al. Like the domestic cat, photoperiod appears to control seasonal reproduction in non- domestic felids. For example, clouded leopards housed indoors with continuous exposure to 12 h of artifcial light per day will cycle year round (Brown et al. Pallas cats are highly seasonal and females exhibit ovarian activity for only ~3 months of the year (Jan-Mar) (Brown et al. However, sudden transitions to long days can stimulate premature follicular steroidogenesis. In one example, ovarian activity was stimulated in a Pallas cat female when she was moved to an outdoor exhibit and then again during a month-long event in november where zoo lights were left on for an additional 5 hours to facilitate night viewing by the public (Festival of Lights) (Brown et al. When the normal seasonal increase in photoperiod occurred, the female responded with an increase in fecal estrogen excretion, but no breeding occurred. Only after she was moved away from the festival lights the following year did conception occur (Brown et al. The gonadotropins ecG and hcG are typically used to stimulate follicular development and induce ovulation, respectively. Recent studies suggest that standard chorionic gonadotropin regimens induce ovarian hyperstimulation, resulting in estrogen concentrations that are several- fold higher than those observed during natural estrus (clouded leopard, Brown et al. The etiology of excessive estrogen production after gonadotropin treatment appears to be due, in part, to the development of ancillary ovarian follicles (Pelican et al. Hyper-estrogenism creates an abnormal endocrine environment that is detrimental to fertilization, embryogenesis and implantation. One exception is the cheetah, where fecal estrogen concentrations after gonadotropin ovulation induction are not different from those associated with natural estrus (Brown et al. In the domestic cat, pregnancy rates are highest when gonadotropins are administered during the interestrus period, when ovarian activity is minimal (Goodrowe and Wildt, 1987; Goodrowe et al. This inactivity could allow the ovary to be more consistently responsive to ecG/hcG because there are few active follicles and no luteal tissue producing endogenous steroids to disrupt exogenous gonadotropin action. Studies are now underway to identify approaches to temporarily shut-down ovarian activity before ovulation induction, which hopefully will result in more normal responses without hyperstimulation (Pelican et al. The diffculty is determining what constitutes stress because not all stressors have negative impacts. It is only a concern when stress causes deleterious effects (Moberg, 1987; Moberg and Mench, 2000). Indeed a lack of stimuli can lead to boredom, with equally detrimental consequences (Vanrooijen, 1991). Analyses of circulating or excreted corticosteroids can provide a physiological indicator of adrenal activity and overall levels of stress. For example, urinary cortisol was increased in domestic cats exposed to a stressful caretaking routine (carlstead et al. Appropriate assays need to be broad spectrum to crossreact with the variety of corticoid metabolites found in cat feces. R4866; University of california, Davis) also has proven effective in measuring fecal corticoids in other carnivore species, like the black-footed ferret (Young et al. However, the two assays detected different glucocorticoid metabolites within each species. Despite that, longitudinal profles were qualitatively similar and data were highly correlated, suggesting both systems were equally effective in monitoring adrenal activity. Thus, a number of options exist for monitoring stress status via adrenal steriods in felids. Studies now are in progress to use fecal corticoid analyses in combination with evaluations of behavior and physiology to provide more meaningful indicators of stress. Fecal corticoids have been shown to be transiently increased following anesthesia (domestic cat, Smith et al. In clouded leopards, comparisons across temperament categories indicated that nervous animals had higher corticoid concentrations than calm individuals (Wielebnowski et al. In another clouded leopard study, cats housed in enclosures with more vertical space or off exhibit had lower fecal corticoid levels, whereas higher corticoids were found in cats housed in close proximity to other large predators and in those displaying self-mutilating behaviors (Wielebnowski et al. Margay and tigrina females exhibited distinct elevations in corticoid concentrations after transfer from large enriched enclosures to smaller barren cages that corresponded with agitated behavior, especially soon after transfer. Fecal corticoid concentrations were then reduced following cage enrichment in tigrinas, but not in margays indicating a species difference in response to enrichment approaches. What we lack for many Felidae species are clearly defned normative data, ranging from the onset of puberty through to reproductive senescence. Identifying the type of ovulation (induced versus spontaneous) and effect of seasonality on reproduction for each species is important because these two characteristics impact both natural and assisted breeding efforts. The ability to easily and safely assess reproductive status, especially through non-invasive means, will allow identifying reproductive problems and developing mediating solutions. One of the most useful benefts of steroid metabolite monitoring will be assessing causes of poor fertility in response to assisted reproductive procedures, eventually allowing these tools to more reliably contribute to species propagation. A high priority is developing ovulation induction protocols that result in consistent responses, without ovarian hyperstimulation, to provide an optimal maternal environment for fertilization and embryo development. Along with this effort is the need to control the reproductive cycle, including down-regulating endogenous ovarian activity and synchronizing estrus (Pelican et al. We also need a quick and reliable single sample test for diagnosing pregnancy, preferably one that is non-invasive.

This means that our so- ciety has been exposed to two powerful new estrogens in the past half century: zearalenone from extra-moldy foods and bisphenol-A in plastic tooth replacements. Surely this could cause sexual dysfunction of various kinds for both men and women. Zearalenone is plentiful in Russet potatoes, potato chips, brown rice and popcorn.

But as the parent of a six month old baby, would you let her eat food sweetened with saccharin? But where safety is the issue, an evaluation committee should be biased (in favor of safety). For instance, an unbiased committee would consider carbon tetrachloride as possibly carcinogenic (because not enough human experiments were done, although animal ex- 89 periments definitely showed cancer induction ) whereas the safety-biased committee would consider it probably or undoubt- edly carcinogenic (because some human experiments were done and these showed cancer induction besides the results from animals). Despite their distinguished personnel, they have made a classification system that confuses and demoralizes the public that relies upon it. I am suggesting that lay people (excluding all professionals) staff committees and set their own standards. We might never see saccharin, azo dyes, mineral oil and lots of other chemicals even near our food and body products again. Although finding what is carcinogenic for people is impor- tant for all of society, finding what carcinogens are in your tu- mors is most important to you.

Mild diarrhea responds well to a more diluted formula with mineral water at a 1:1 ratio until diarrhea stops 150 mg rulide mastercard. In more serious cases discount rulide 150mg amex, take the cub off formula completely and give only electrolytes (a 5-10% glucose solution) discount rulide 150mg fast delivery, using the same amount and feeding schedule as with formula until diarrhea stops (Andrews, 1998). In these cases a veterinary intervention is needed to start an intravenous or subcutaneous treatment. Gradually reintroduce formula, beginning with half the strength of what it was before withdrawing, then slowly work up to its original strength as stools frm. Bene-bac by PetAg, a gel that stabilizes the natural gut fora of kittens, is very effective (Andrews, 1998). Antibiotics are not recommended, particularly for treating diarrhea, as they often upset the kittens normal growth of bacterial gut fora. Another possibility is to give the cub a few drops of corn syrup added to each bottle for 2-3 feedings (Andrews, 1998). If the cub does not defecate after the treatment explained above, a very mild warm soapy enema can be given. Use electrolyte therapy 121 as for diarrhea or use nutrical at a rate of 4 cc daily divided by the number of feedings (Andrews, 1998). It may be due to the cub not being used to the bottle or to the cub being given too much food. Apply the following technique to clear the airways: hold the cub belly down on the palm of your right hand, placing its head between the index and middle fngers. Place the palm of your left hand on the cubs back, holding the upper part of its head with the fngers of this hand. Bend forward with your legs fexed and swing the cub between your legs gently but frmly so that it can expel the fuid from its airways. This technique must be used with caution, as it could cause a brain hemorrhage if it is done violently. Risk is highest in the frst few post-natal weeks, when body temperature ranges between 35-37 c, the shivering refex is not yet present and there is not much subcutaneous fat (Prats, 2008). This may cause a malfunction of the0 respiratory system and ultimately lead to cardiac arrest. Domestic kittens whose rectal temperature is <34 c0 are in serious danger (Gunn-Moore, 2006a). It should be done in a timeframe lasting between 1 to 4 hours, depending on the severity of hypothermia. A rapid increase in temperature may cause cardiovascular collapse and death of the animal. Raising the temperature too much can also cause dehydration of the cub and also lead to its death. Hypothermia reduces the absorption capacity of the gut and thus leads to poor digestion, which easily leads to hypoglycemic episodes (see Hypoglycemia). Do no provide formula, only eletrolytes, until the cub recuperates its normal temperature. If the mother is not available, serum can be taken from another healthy individual that has spent over a year in the breeding programme and whose serology study proves that it has good antibody titers. Serum must be separated in 4-6 ml aliquots; it can be frozen and thawed out for its use, although it is always better to provide it fresh. The recommended dosages are as follows (Prats, 2004):0 Oral: 2 ml/100 g body weight every 12 hours. Oral route has the slight problem that the volume that can be given is limited by the cubs stomach size, and also that it competes with the administration of other nutrients. If a cub refuses several feedings or food is not being assimilated because of a problem e. Treatment involves giving the cub a few drops of corn syrup orally as a source of energy. In this case parenteral treatment and stabilization of the cubs temperature should begin at the same time (Gunn-Moore, 2006a) (see Treating hypothermic cubs). If the cub still does not accept food, surgery will be needed to insert feeding tubes into the cubs stomach and feed it artifcially. The objectives of hand-rearing an animal must be clearly defned from the beginning. Will the animal be used in education programmes and therefore be in contact with humans? It sometimes requires great effort and time to check whether the fnal objective has not been compromised or undermined by our intervention. Hand- rearing is not recommended for cubs that will be reintroduced into the wild. Hand-rearing implies the risk of raising cubs that will exhibit an abnormal behavior for their species. The sensitive period for socialization is considered to take place between the 2nd and 20th week of a cubs life. This is the beginning of a developmental period during which they rapidly learn from external stimuli. They exclusively depend on their mothers milk until they are about nine weeks old although they may continue to suckle until they are three or four months old. This period of dependence on the mother is considered to be vital for the development of different behavioral traits. It is important that the animals have contact with other individuals of their species during the sensitive period for socialization (Read and Meier, 1996). If this is not possible, they should be in contact with other felid species, preferably of the genus Lynx. If this does not happen, their adult behavior might be altered and they may not show any interest in mating with individuals of their species upon reaching sexual maturity. As long as contact with other lynx is ensured, contact with humans does not seem to alter the development of reproductive behavior. However, regular contact with humans in cubs between two and 20 weeks of age can lead to very tame animals that are not afraid of humans. This may pose problems for handling these individuals once they have reached maturity. On most occasions, it involves handling Iberian lynx cubs that are only a few days old and sometimes even prematurely born.

Tsetse fies of the genus Glossina trans- mit trypanosomes throughout a broad region of equatorial Africa, ecologically restricted to the boundaries of the Sahara desert to the north and the dryer temperate regions south of the equator. African Trypanosomiasis 63 David Bruce described the disease and its causative agent by showing that nagana, a disease of cattle, was caused by trypano- somes, and that tsetse fies were the vec- 12 tors. In 1902, Robert Forde, working in West Africa, described a clinical condition in humans similar to that in cattle caused by 13 T.

African trypanosomes have evolved 35 diately after they are ingested by the vector. The trypanosomes then develop into procy- clic trypomastigotes in the midgut of the fy, and continue to divide for approximately 10 days. When the division cycles are completed, the organisms migrate to the salivary glands, and transform into epimastigotes. This form, in turn, divides and transforms further into the metacyclic try- panosome stage, and is infective for humans and reservoir hosts.
