| analysis of the mitochondrial genome of cheetahs (acinonyx jubatus) with neurodegenerative disease. | the complete mitochondrial genome of acinonyx jubatus was sequenced and mitochondrial dna (mtdna) regions were screened for polymorphisms as candidates for the cause of a neurodegenerative demyelinating disease affecting captive cheetahs. the mtdna reference sequences were established on the basis of the complete sequences of two diseased and two nondiseased animals as well as partial sequences of 26 further individuals. the a. jubatus mitochondrial genome is 17,047-bp long and shows a high sequ ... | 2004 | 15302412 |
| validation of the 13c-urea breath test for use in cheetahs (acinonyx jubatus) with helicobacter. | historically, therapeutic monitoring for prescribed eradication treatment of helicobacter in cheetahs (acinonyx jubatus) with associated gastritis has been accomplished only through endoscopic biopsies. the 13c-urea breath test (ubt) can offer an alternative to repeated biopsies for therapeutic monitoring. five male and five female cheetahs and one male sumatran tiger (panthera tigris) were studied. all were clinically healthy before and after this investigation. breath samples of end-tidal expi ... | 2004 | 15305506 |
| vaccine-induced protection against anthrax in cheetah (acinonyx jubatus) and black rhinoceros (diceros bicornis). | institution of a policy of vaccination in endangered species with a vaccine not previously administered to it cannot be undertaken lightly. this applies even more in the case of cheetah (acinonyx jubatus) with their unusually monomorphic gene pool and the potential restrictions this places on their immune responses. however, the recently observed mortalities from anthrax in these animals in the etosha national park, namibia, made it imperative to evaluate vaccination. black rhinoceros (diceros b ... | 2004 | 15308358 |
| comparison of helicobacter spp. in cheetahs (acinonyx jubatus) with and without gastritis. | chronic gastritis causes significant morbidity and mortality in captive cheetahs but is rare in wild cheetahs despite colonization by abundant spiral bacteria. this research aimed to identify the helicobacter species that were associated with gastritis in captive cheetahs but are apparently commensal in wild cheetahs. helicobacter species were characterized by pcr amplification and sequencing of the 16s rrna, urease, and caga genes and by transmission electron microscopy of frozen or formalin-fi ... | 2005 | 15634976 |
| an ancillary tool for the diagnosis of amyloid a amyloidosis in a variety of domestic and wild animals. | immunohistochemistry, the standard method for diagnosing amyloid a (aa) amyloidosis, is limited in animals because it requires a large array of animal-specific anti-aa antibodies, not commercially available. the shtrasburg method (sh method) is a highly specific and sensitive technique, helping in the diagnosis and determination of aa amyloidosis in humans. the aim of this study is to determine whether the sh method is applicable in the diagnosis of aa amyloidosis in a variety of animals. tissue ... | 2005 | 15753466 |
| phylogenetic studies of pantherine cats (felidae) based on multiple genes, with novel application of nuclear beta-fibrinogen intron 7 to carnivores. | the pantherine lineage of the cat family felidae (order: carnivora) includes five big cats of genus panthera and a great many midsized cats known worldwide. presumably because of their recent and rapid radiation, the evolutionary relationship among pantherines remains ambiguous. we provide an independent assessment of the evolutionary history of pantherine lineage using two complete mitochondrial (mt) genes (nd2 and nd4) and the nuclear beta-fibrinogen intron 7 gene, whose utility in carnivoran ... | 2005 | 15804417 |

| interspecific scaling of the morphology and posture of the limbs during the locomotion of cats (felidae). | for phylogenetically diverse mammals, ranging from small rodents to large ungulates, the generalization that limb erectness increases with increased size is supported by some size-dependent scaling relationships of appendicular skeletal anatomy as well as a limited number of direct observations of limb posture during locomotion. if size alone is the causal basis for different limb posture, then the erectness of limbs should increase significantly with increased size within a phylogenetically nar ... | 2007 | 17267650 |
| the composition of serval (felis serval) milk during mid-lactation. | milk was obtained from three captive servals. the average nutrient content was 158.3+/-44.4 g protein; 152.6+/-62.3 g fat; and 68.7+/-31.4 g lactose per kg milk. the protein fraction respectively consisted of 117.7+/-44.8 g caseins per kg milk and of 40.6+/-6.7 g whey proteins per kg milk. electrophoresis and identification of protein bands showed a similar migrating sequence of proteins as seen in cheetah and cat milk, with small differences in the beta-caseins. the lipid fraction contains 313. ... | 2007 | 17307374 |
| efficacy and long-term outcome of gastritis therapy in cheetahs (acinonyx jubatus). | a prospective clinical trial evaluating efficacy and long-term outcome of treatments for lymphoplasmacytic gastritis in cheetahs (acinonyx jubatus) was conducted. the study evaluated efficacy of 11 different antibiotic and antiinflammatory treatment protocols in 32 cheetahs (19 male, 13 female) for reducing gastric inflammation and helicobacter colonization and monitored the course of disease through histologic grading of gastric biopsies. all cheetahs were biopsied up to i wk before treatment a ... | 2005 | 17312757 |
| radiologic anatomy of the normal appendicular skeleton of the lion (panthera leo). part 1: thoracic limb. | thoracic limb specimens from 12 euthanized free-ranging lions (panthera leo, 16-170 mo old) underwent radiographic evaluation. the radiographic anatomy was described but excluded any areas of the bones with possible bone pathology. comparisons between adult and juvenile lions were made and physes described. differences or similarities (or both) to cheetahs (acinonyx jubatus) and domestic cats and dogs were also noted. no dissections were made to corroborate the anatomic observations, but compari ... | 2005 | 17315453 |
| validating a commercially available enzyme immunoassay for the determination of 17beta-estradiol and progestogens in the feces of cheetahs (acinonyx jubatus): a case report. | fecal 17beta-estradiol and progestogens excretion was monitored in adult, female cheetahs (acinonyx jubatus; n = 2), zgg-12301 (born 3 april 1993), gonadotrophin treated and zgt-3301, (born 19 august 1993), nontreated, for 120 days using commercially available plate enzyme immunoassay kits prepared for human serum or plasma. there were significant differences (p < 0.001) between baseline and peak concentrations of both hormone measures. female zgg-12301, which conceived, but this pregnancy resul ... | 2005 | 17315457 |
| radiographic kidney measurements in captive cheetahs (acinonyx jubatus). | the prevalence of chronic renal disease is substantial among captive cheetahs (acinonyx jubatus). the purpose of this study was to determine kidney measurements from radiographs of captive cheetahs (n = 15) with normal renal function. the ratio of kidney length to length of the body of the second lumbar vertebrae has been established for domestic cats with normal renal function. the mean ratio of renal length to length of the second lumbar vertebra was 1.81 +/- 0.14 in cheetahs. this baseline da ... | 2005 | 17323577 |
| the mitochondrial genome structure of the clouded leopard (neofelis nebulosa). | the complete 16 844 bp mitochondrial genome of neofelis nebulosa has been sequenced and compared with the complete mitochondrial genomes of felis catus and the acinonyx jubatus. the base composition of the mitochondrial genome of n. nebulosa is as follows: a, 5343 bp (31.7%); c, 4441 bp (26.4%); g, 2491 bp (14.8%); t, 4569 bp (27.1%). the genome complement and the gene order of this mitochondrial genome was found to be typical of those reported for other mammals. several unusual features of this ... | 2007 | 17546090 |
| challenges in cryopreserving endangered mammal spermatozoa: morphology and the value of acrosomal integrity as markers of cryo-survival. | the science of cryobiology is essential to the effective, practical use of semen for assisted breeding to help manage small populations of rare wildlife species. in this review, we describe challenges associated with cryopreserving gametes from wild fauna. based on more than 25 years of experience across a diversity of mammals, it appears that the primary driving force dictating cryo-survival of a spermatozoon is its initial pre-freeze quality and morphology, especially having a morphologically ... | 2007 | 17644982 |
| a cheetah-like cat in the north american pleistocene. | the discovery of abundant skeletal remains of felis trumani from a late pleistocene deposit in wyoming shows that it was as highly modified for cursorial locomotion as the cheetah (acinonyx). several other pleistocene felids that have been regarded as pumas seem to be related forms. the late pleistocene fauna of the big horn basin in wyoming is dominated by cursorial taxa. | 1977 | 17735673 |
| the cheetah is depauperate in genetic variation. | a sample of 55 south african cheetahs (acinonyx jubatus jubatus) from two geographically isolated populations in south africa were found to be genetically monomorphic at each of 47 allozyme (allelic isozyme) loci. two-dimensional gel electrophoresis of 155 abundant soluble proteins from cheetah fibroblasts also revealed a low frequency of polymorphism (average heterozygosity, 0.013). both estimates are dramatically lower than levels of variation reported in other cats and mammals in general. the ... | 1983 | 17755482 |
| acute disseminated toxoplasmosis in a juvenile cheetah (acinonyx jubatus). | a juvenile cheetah (acinonyx jubatus) died with rapidly progressive pyrexia, tachypnea, abdominal effusion, and hepatomegaly. postmortem examination revealed lesions consistent with acute disseminated infection with toxoplasma gondii. the presence of this organism was confirmed in multiple organs by immunohistochemistry and polymerase chain reaction. to the best of our knowledge, we propose this to be the first reported case of primary acute disseminated toxoplasmosis in a cheetah. | 2007 | 17939359 |
| induction of murine aa amyloidosis by various homogeneous amyloid fibrils and amyloid-like synthetic peptides. | we investigated amyloid-enhancing factor (aef) activity of amyloid fibrils extracted from amyloid-laden livers of mice, cow, cheetah, cat and swan. all amyloid fibrils were confirmed to be amyloid protein a (aa) by an immunohistochemical analysis. we found that these fibrils accelerated the deposition of amyloid in an experimental mouse model of aa amyloidosis. furthermore, the degree of deposition was dependent on the concentration of fibrils. when we compared the minimal concentration of amylo ... | 2007 | 17953525 |
| molecular genetic insights on cheetah (acinonyx jubatus) ecology and conservation in namibia. | the extent and geographic patterns of molecular genetic diversity of the largest remaining free-ranging cheetah population were described in a survey of 313 individuals from throughout namibia. levels of relatedness, including paternity/maternity (parentage), were assessed across all individuals using 19 polymorphic microsatellite loci, and unrelated cheetahs (n = 89) from 7 regions were genotyped at 38 loci to document broad geographical patterns. there was limited differentiation among regions ... | 2008 | 17982159 |
| predator-prey size relationships in an african large-mammal food web. | 1. size relationships are central in structuring trophic linkages within food webs, leading to suggestions that the dietary niche of smaller carnivores is nested within that of larger species. however, past analyses have not taken into account the differing selection shown by carnivores for specific size ranges of prey, nor the extent to which the greater carcass mass of larger prey outweighs the greater numerical representation of smaller prey species in the predator diet. furthermore, the top- ... | 2008 | 18177336 |
| the complete mitochondrial genome structure of snow leopard panthera uncia. | the complete mitochondrial genome (mtdna) of snow leopard panthera uncia was obtained by using the polymerase chain reaction (pcr) technique based on the pcr fragments of 30 primers we designed. the entire mtdna sequence was 16 773 base pairs (bp) in length, and the base composition was: a-5,357 bp (31.9%); c-4,444 bp (26.5%); g-2,428 bp (14.5%); t-4,544 bp (27.1%). the structural characteristics [0] of the p. uncia mitochondrial genome were highly similar to these of felis catus, acinonyx jubat ... | 2009 | 18431688 |
| cheetahs of the deep sea: deep foraging sprints in short-finned pilot whales off tenerife (canary islands). | 1. empirical testing of optimal foraging models for breath-hold divers has been difficult. here we report data from sound and movement recording dtags placed on 23 short-finned pilot whales off tenerife to study the foraging strategies used to catch deep-water prey. 2. day and night foraging dives had a maximum depth and duration of 1018 m and 21 min. vocal behaviour during dives was consistent with biosonar-based foraging, with long series of echolocation clicks interspersed with buzzes. simila ... | 2008 | 18444999 |
| fecal transmission of aa amyloidosis in the cheetah contributes to high incidence of disease. | aa amyloidosis is one of the principal causes of morbidity and mortality in captive cheetahs (acinonyx jubatus), which are in danger of extinction, but little is known about the underlying mechanisms. given the transmissible characteristics of aa amyloidosis, transmission between captive cheetahs may be a possible mechanism involved in the high incidence of aa amyloidosis. in this study of animals with aa amyloidosis, we found that cheetah feces contained aa amyloid fibrils that were different f ... | 2008 | 18474855 |
| seroepidemiology of toxoplasma gondii in zoo animals in selected zoos in the midwestern united states. | toxoplasma gondii infections in zoo animals are of interest because many captive animals die of clinical toxoplasmosis and because of the potential risk of exposure of children and elderly to t. gondii oocysts excreted by cats in the zoos. seroprevalence of t. gondii antibodies in wild zoo felids, highly susceptible zoo species, and feral cats from 8 zoos of the midwestern united states was determined by using the modified agglutination test (mat). a titer of 1:25 was considered indicative of t. ... | 2008 | 18605803 |
| refinement of a commercial bench-top relaxin assay for pregnancy diagnosis using urine from domestic and nondomestic felids. | relaxin, a 6-kda polypeptide hormone, is excreted in the urine during pregnancy in several mammalian species. a recent study showed that detection of urinary relaxin using a bench-top serum assay (witness relaxin kit, synbiotics corp., san diego, california 92127, usa) can be diagnostic for pregnancy in domestic cats (felis silvestris catus), but it is unknown whether the bench-top kit is applicable with urine across felid species. our objectives were to 1) examine modifications in urine process ... | 2008 | 18634207 |
| naturally acquired anthrax antibodies in a cheetah (acinonyx jubatus) in botswana. | an outbreak of anthrax in the jwana game reserve in jwaneng, botswana, was first observed when three cheetahs (acinonyx jubatus) died of the disease in november 2004. in the aftermath of this event, banked serum samples collected from 23 wild-caught cheetahs were examined, by the inhibition enzyme-linked immunoassay (elisa), for antibodies to the protective antigen (pa) of bacillus anthracis. of the 23 cheetahs, 16 regularly accessed the reserve. antibodies to pa were detected in one cheetah col ... | 2008 | 18689661 |
| molecular detection of babesia rossi and hepatozoon sp. in african wild dogs (lycaon pictus) in south africa. | blood specimens from wild dogs (n=301) were obtained from de wildt cheetah and wildlife centre (pretoria) and five game reserves (4 in the north-west province and 1 in limpopo province), south africa. specimens were screened for babesia, theileria, hepatozoon and ehrlichia/anaplasma species using pcr and reverse line blot (rlb) assays. positive results were obtained in 18 (6%) wild dogs. sixteen specimens were found positive for babesia rossi and two dogs were hepatozoon sp. positive. it appears ... | 2008 | 18752897 |
| motions of the running horse and cheetah revisited: fundamental mechanics of the transverse and rotary gallop. | mammals use two distinct gallops referred to as the transverse (where landing and take-off are contralateral) and rotary (where landing and take-off are ipsilateral). these two gallops are used by a variety of mammals, but the transverse gallop is epitomized by the horse and the rotary gallop by the cheetah. in this paper, we argue that the fundamental difference between these gaits is determined by which set of limbs, fore or hind, initiates the transition of the centre of mass from a downward- ... | 2009 | 18854295 |
| a primitive late pliocene cheetah, and evolution of the cheetah lineage. | the cheetah lineage is a group of large, slender, and long-limbed cats with a distinctive skull and dental morphology, of which only the extant cheetah (acinonyx jubatus) is present today. the lineage is characterized by having abbreviated, tall, and domed crania, and a trenchant dentition with a much reduced, posteriorly placed protocone on the upper carnassial. in this article, we report on a new discovery of a late pliocene specimen from china with an estimated age of approximately 2.2-2.5 mi ... | 2009 | 19114651 |
| characterization of an outbreak of astroviral diarrhea in a group of cheetahs (acinonyx jubatus). | a mamastrovirus was identified in an outbreak of diarrhea in cheetahs (acinonyx jubatus). five young adult and two adult cheetahs presented with lethargy, anorexia, watery diarrhea and regurgitation over an 11-day period. fecal samples were submitted for electron microscopy and culture. electron microscopy results revealed particles morphologically consistent with an astrovirus, and no other viral pathogens or significant bacterial pathogens were identified. the astrovirus was confirmed and sequ ... | 2009 | 19171442 |
| comparative thermoregulation and the quest for athletic supremacy. | there are a number of different strategies used by animals to effectively deal with the changing environment. the various thermoregulatory strategies employed by mammals can be a critical factor determining the survival and physical performance in a range of conditions. however, it is not readily appreciated that mammals regulate their body temperature in different ways and it is usually assumed that the mechanisms for temperature regulation are very similar amongst all endotherms. in this chapt ... | 2008 | 19208996 |

| immunohistochemical study of prp(sc) distribution in neural and extraneural tissues of two cats with feline spongiform encephalopathy. | two domestic shorthair cats presenting with progressive hind-limb ataxia and increased aggressiveness were necropsied and a post mortem diagnosis of feline spongiform encephalopathy (fse) was made. a wide spectrum of tissue samples was collected and evaluated histologically and immunohistologically for the presence of prpsc. | 2009 | 19335885 |
| comparison of several types of enrichment for captive felids. | enrichment can increase the complexity of the captive environment and possibly enhance captive animals' well-being by stimulating active behaviors and reducing stereotypical behaviors commonly seen in zoo felids. in this study, three different enrichment items were added to outdoor enclosures of felids at the montgomery zoo to test their effects on activity levels and stereotypic pacing. bones, frozen fish, and spices (cinnamon, chili powder, and cumin) were presented over a 3-month period to si ... | 2007 | 19360587 |
| phylogeny of a novel "helicobacter heilmannii" organism from a japanese patient with chronic gastritis based on dna sequence analysis of 16s rrna and urease genes. | "helicobacter heilmannii" is an uncultivable spiral-shaped bacterium inhabiting the human gastric mucosa. it is larger and more tightly-coiled than h. pylori. we encountered a patient with chronic gastritis infected a "h. heilmannii"-like organism (hhlo), designated as sh6. gastric mucosa derived from the patient was orally ingested by specific pathogen free mice. colonization of the mice by sh6 was confirmed by electron microscopy of gastric tissue specimens. in an attempt to characterize sh6, ... | 2009 | 19412605 |
| oral examination and radiographic evaluation of the dentition in wild cats from namibia. | feline tooth resorption has been widely reported in domestic cats and sporadically described in other felidae. the goal of the present study was to determine the prevalence of tooth resorption and to report other dental problems in a population of wild felidae. observations of dental disorders and anomalies were made in skulls from 73 wild felidae (cheetahs, leopards, caracals, african wildcats, and lions) originating from namibia. in addition, radiographs were taken in 43 cases to determine sig ... | 2009 | 19476083 |
| real-time reinforcement learning by sequential actor-critics and experience replay. | actor-critics constitute an important class of reinforcement learning algorithms that can deal with continuous actions and states in an easy and natural way. this paper shows how these algorithms can be augmented by the technique of experience replay without degrading their convergence properties, by appropriately estimating the policy change direction. this is achieved by truncated importance sampling applied to the recorded past experiences. it is formally shown that the resulting estimation b ... | 2009 | 19523786 |
| possible case of maternal transmission of feline spongiform encephalopathy in a captive cheetah. | feline spongiform encephalopathy (fse) is considered to be related to bovine spongiform encephalopathy (bse) and has been reported in domestic cats as well as in captive wild cats including cheetahs, first in the united kingdom (uk) and then in other european countries. in france, several cases were described in cheetahs either imported from uk or born in france. here we report details of two other fse cases in captive cheetah including a 2(nd) case of fse in a cheetah born in france, most likel ... | 2009 | 19738899 |
| advances in reproductive science for wild carnivore conservation. | knowledge about reproduction is critical for predicting the viability of wildlife populations in nature and for managing breeding programmes in captivity. intensive species-based studies are the priority, because reproductive mechanisms are extraordinarily diverse, even within the same taxonomic family. carnivores deserve more attention as such species are highly vulnerable to environmental change and human persecution. the present review provides contemporary illustrations of how reproductive s ... | 2009 | 19754535 |
| myosin heavy chain composition of tiger (panthera tigris) and cheetah (acinonyx jubatus) hindlimb muscles. | felids have a wide range of locomotor activity patterns and maximal running speeds, including the very fast cheetah (acinonyx jubatas), the roaming tiger (panthera tigris), and the relatively sedentary domestic cat (felis catus). as previous studies have suggested a relationship between the amount and type of activity and the myosin heavy chain (mhc) isoform composition of a muscle, we assessed the mhc isoform composition of selected hindlimb muscles from these three felid species with differing ... | 2010 | 19768738 |
| evaluation of nutrient digestibility and fecal characteristics of exotic felids fed horse- or beef-based diets: use of the domestic cat as a model for exotic felids. | the objective of this study was to determine the effects of feeding commercially available beef- and horse-based diets on nutrient digestibility and fecal characteristics of large captive exotic felids and domestic cats. four species of large exotic felids including cheetahs, malayan tigers, jaguars, and amur tigers, and domestic cats were utilized in a crossover design. raw meat diets included a beef-based diet (57% protein; 28% fat) and a horse-based diet (51% protein; 30% fat). all cats were ... | 2010 | 19830746 |
| periaortic haemangiosarcoma in an african wild dog (lycaon pictus). | a 9-year-old apparently healthy male african wild dog (lycaon pictus) was found dead in its enclosure at the de wildt cheetah and wildlife centre. necropsy revealed a pericardium distended by approximately 250 ml of thick blood. a soft, red, lobulated mass was attached to the periaortic fat between the level of the aortic valves and the pericardial reflection. histologically, the mass was consistent with a haemangiosarcoma. other findings in the heart included mild to moderate ventricular hypert ... | 2009 | 19831274 |
| a comparative approach to the study of keeper-animal relationships in the zoo. | research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. this article begins to explore some of the factors that need to be considered to investigate keeper-animal relationships (kars) in the zoo. in the mid-1990s, a large body of multi-institutional data on zookeepers and animals was collected from 46 zoos. using standardized questionnaires, 8 ... | 2009 | 19885915 |
| dogs, cats, and kin: a molecular species-level phylogeny of carnivora. | phylogenies underpin comparative biology as high-utility tools to test evolutionary and biogeographic hypotheses, inform on conservation strategies, and reveal the age and evolutionary histories of traits and lineages. as tools, most powerful are those phylogenies that contain all, or nearly all, of the taxa of a given group. despite their obvious utility, such phylogenies, other than summary 'supertrees', are currently lacking for most mammalian orders, including the order carnivora. carnivora ... | 2010 | 19900567 |
| lion (panthera leo) and cheetah (acinonyx jubatus) ifn-gamma sequences. | cloning and sequencing of the full length lion and cheetah interferon-gamma (ifn-gamma) transcript will enable the expression of the recombinant cytokine, to be used for production of monoclonal antibodies and to set up lion and cheetah-specific ifn-gamma elisas. these are relevant in blood-based diagnosis of bovine tuberculosis, an important threat to lions in the kruger national park. alignment of nucleotide and amino acid sequences of lion and cheetah and that of domestic cats showed homologi ... | 2010 | 19913304 |
| feline immunodeficiency virus (fiv) in wild pallas' cats. | feline immunodeficiency virus (fiv), a feline lentivirus related to hiv, causes immune dysfunction in domestic and wild cats. the pallas' cat is the only species from asia known to harbor a species-specific strain of fiv designated fiv(oma) in natural populations. here, a 25% seroprevalence of fiv is reported from 28 wild mongolian pallas' cats sampled from 2000 to 2008. phylogenetic analysis of proviral rt-pol from eight fiv(oma) isolates from mongolia, russia, china and kazakhstan reveals a un ... | 2010 | 19926144 |
| seroprevalences to viral pathogens in free-ranging and captive cheetahs (acinonyx jubatus) on namibian farmland. | cheetah populations are diminishing rapidly in their natural habitat. one reason for their decline is thought to be a high susceptibility to (infectious) diseases because cheetahs in zoos suffer from high disease-induced mortality. data on the health status of free-ranging cheetahs are scarce, and little is known about their exposure and susceptibility to infectious diseases. we determined seroprevalences to nine key viruses (feline herpesvirus 1, feline calicivirus, feline parvovirus, feline co ... | 2010 | 19955325 |
| [histopathology of strobilocercosis found in the livers of white mouse.] | the adult form of taenia taeniaeformis is found in the intestine of the cat and cheetah. the larva form is called strobilocercus fasciolaris and is found in rodents such as mice and rats. our objective was to draw attention to that rare zoonosis, since it has already been reported in the literature as strobilocercosis in humans. during an experimental animal study conducted at inonu university, some unexpected cystic formations were found in the livers of nine 6-8-month-old healthy white mice, w ... | 2010 | 20340085 |
| babesia lengau sp. nov., a novel babesia species in cheetah (acinonyx jubatus, schreber, 1775) populations in south africa. | in a previous paper, we reported on a large number of cheetah blood specimens that gave positive signals only for babesia and/or theileria genus-specific probes on the reverse line blot (rlb) assay, indicating the presence of a novel species or variant of an existing species. some of these specimens were investigated further by microscopic, serological, sequencing, and phylogenetic analyses. the near-full-length 18s rrna genes of 13 samples, as well as the second internal transcribed spacer (its ... | 2010 | 20519464 |
| evidence for compromised metabolic function and limited glucose uptake in spermatozoa from the teratospermic domestic cat (felis catus) and cheetah (acinonyx jubatus). | cheetahs and certain other felids consistently ejaculate high proportions (≥ 60%) of malformed spermatozoa, a condition known as teratospermia, which is prevalent in humans. even seemingly normal spermatozoa from domestic cat teratospermic ejaculates have reduced fertilizing capacity. to understand the role of sperm metabolism in this phenomenon, we conducted a comparative study in the normospermic domestic cat versus the teratospermic cat and cheetah with the general hypothesis that sperm metab ... | 2010 | 20650882 |
