Carnivorous members of the Carnivora reside at the apex of food chains and consume meat-only diets, rich in purine, fats and protein. Here, we aimed to identify potential adaptive evolutionary signatures compatible with high purine and fat metabolism based on analysis of host genomes and symbiotic gut microbial metagenomes. We found that the gut microbiomes of carnivorous Carnivora (e.g. Felidae, Canidae) clustered in the same clade, and other clades comprised omnivorous and herbivorous Carnivora (e.g. badgers, bears and pandas)...

Hyenas (family Hyaenidae), as the sister group to cats (family Felidae), represent a deeply diverging branch within the cat-like carnivores (Feliformia). With an estimated population size of less than 10,000 individuals worldwide, the brown hyena (Parahyaena brunnea) represents the rarest of the four extant hyena species and has been listed as Near Threatened by the IUCN. Here we report a high coverage genome from a captive bred brown hyena and both mitochondrial and low-coverage nuclear genomes of 14 wild-caught brown hyena individuals from across southern Africa...

Parasitic diseases affecting wild carnivores remain largely unknown or poorly described. Dioctophymosis is a parasitosis caused by the nematode Dioctophyme renale that is found worldwide. It affects domestic and wild animals and has been reported frequently in Brazil. This paper reports dioctophymosis in a wild felid for the first time.

Tuberculosis is a significant problem globally for domestic animals as well as captive and free ranging wild life. Rapid point of care (POC) serology kits are well suited for the diagnosis of TB in wild animals. However, wild animals are invariably exposed to environmental non-pathogenic mycobacterium species with the development of cross reacting antibodies. In the present study, POC TB diagnosis kit was developed using a combination of pathogenic Mycobacteria specific recombinant antigens and purified protein derivatives of pathogenic and non-pathogenic Mycobacteria...

The data set represents the first attempt at a large-scale inventory of non-volant mammals, with potential applications to performing macroecological studies, developing conservation strategies, and undertaking population and community ecology research, but also to evaluate the ecological consequences of fragmentation and defaunation. Our objectives for compiling these data were to summarize information about inventories of non-volant mammals in the critically important area of the Upper Paraná River Basin by focusing on species richness and index of frequency of occurrence and to identify gaps in knowledge regarding non-volant mammal communities in order to guide future sampling efforts...

Leopardus wiedii (margay) is the only arboreal Neotropical felid able to climb head-first down trees, due to its ability to rotate its tarsal joint 180°. A closely related, similar-sized species, L. geoffroyi (Geoffroy's cat) exhibits more typical terrestrial habits and lacks the arboreal capabilities of L. wiedii. There is osteological evidence that supports a mechanical specialization of L. wiedii's tarsal joint for inversion, but there have been no studies on the myology of this specialization. Based on comparative gross-anatomy dissections of zeugo- and autopodial muscles related to the ankle joint of one margay specimen and two Geoffroýs cats, we identified myological specializations of L...

Lilies are considered nephrotoxic only to domestic cats, which belong to the family Felidae of the suborder Feliformia. However, a 7-month-old female meerkat, belonging to the family Herpestidae of the suborder Feliformia, presented with oliguria, seizure, tachypnea, self-biting, and nystagmus after it ingested lilies. The meerkat died approximately 40 hr after lily ingestion. Gross and histopathologic lesions consistent with acute renal failure were conspicuous in the animal. The renal lesions were acute tubular necrosis, corresponding to the typical pathological changes of lily toxicosis in cats...

Oral squamous cell carcinoma (SCC) is a common finding in domestic and wild felids. Only two cases of oral SCC have been reported in Lynx species (Lynx rufus and Lynx canadensis), at mandibular and gingival sites. In this study, we describe the first report of tongue SCC in a 15 years old female European lynx (Lynx lynx), along with viral investigations. Necropsy and histological analysis were performed and the presence of papillomavirus (PV) infection was investigated by ultrastructural and molecular methods...

In the past decade, studies on reproductive biology, endocrinology, and assisted reproductive technologies (ARTs) in the domestic cat have contributed to a lot of progress in conservation breeding of wild felids. However, the 36 species of the Felidae family have species- and individual-specific reproductive cycles and respond differently to exogenous hormones. Monitoring the ovarian cycle of wild felids can improve their natural breeding and maximize their reproductive success. Moreover, fundamental knowledge on the hormonal patterns of each feline species offers the opportunity to develop ARTs, particularly in threatened and endangered species...

To improve our understanding of Feline calicivirus (FCV) infection in cats in Northeast China, 1584 serum samples from 974 domestic cats and 610 stray cats were collected between 2012 and 2015. The samples were tested for FCV antibodies using a commercially available ELISA kit. The results revealed an overall seroprevalence of 37.56% (595/1584), a seroprevalence in domestic cats of 32.85% (320/974) and a seroprevalence in stray cats of 45.08% (275/610). Risk factor analysis indicated that species was the only risk factor for the presence of FCV (OR=1...

We analysed two sets of mitochondrial (mt) DNA data from tigrinas (traditionally, Leopardus tigrinus) we sampled in Costa Rica, Venezuela, Colombia, Ecuador, Peru, Bolivia, northwestern and northeastern Argentina and southern Brazil. Additionally, the analysis included some GenBank sequences from southern, central and northeastern Brazil. The first mt set (mt ATP8+mt 16S rRNA with 41 tigrina) revealed the existence of seven different tigrina-like haplogroups. They could represent, at least, 4-6 different tigrina species following the Phylogenetic Species Concept (PSC)...

BACKGROUND: Toxocariasis is a prevalent zoonosis disease caused by the closely related nematode species Toxocara canis and Toxocara cati which parasitise Canidae and Felidae respectively. In paratenic hosts, larvae of these worms cause multiple organ damage. However, how these paratenic hosts response to these worms and whether any common biomarker can be applied for diagnosis are still unclear. METHODS: Excreted/secreted (E/S) antigens were prepared by culture of T...

The tendency for sexual size dimorphism (SSD) to increase with body mass in taxa where males are larger, and to decrease when females are larger, is known as Rensch's rule. In mammals, where the trend occurs, it is believed to be the result of a competitive advantage for larger males, while female mass is constrained by the energetics of reproduction. Here, we examine the allometry of SSD within the Felidae and Canidae, demonstrating distinctly different patterns: in felids, there is positive allometric scaling, while there is no trend in canids...

Toxoplasma gondii is an apicomplexan parasite capable of infecting a wide variety of warm-blooded animals, including birds and humans and is zoonotically important too. Felidae serve its definitive hosts and most infections are inoccous while in various intermediate hosts (e.g. sheep), it is responsible for abortion, still births. Humans which are immune compromised are also susceptible to toxoplasmosis. Most of the epidemiological studies have revealed it to be belonging to three clonal types with exceptions in South Africa having atypical isolates...

BACKGROUND: Previous studies have demonstrated that the clear morphological differences among vertebrae across the presacral column are accompanied by heterogeneous functional signals in vertebral shape. Further, several lines of evidence suggest that the mammalian axial skeleton is a highly modular structure. These include its composition of serial units, a trade-off between high shape variance and strong conservation of vertebral count, and direct association of regions with anterior expression sites of Hox genes...

UDP-glucuronosyltransferases (UGTs) are among the most important xenobiotic metabolizing enzymes that conjugate a wide range of chemicals. Previous studies showed that Felidae and Pinnipedia species have very low UGT activities toward some phenolic compounds because of the UGT1A6 pseudogene and small numbers of UGT1A isozymes. In addition to the UGT1As, UGT2Bs isozymes also conjugate various endogenous (eg, estrogens, androgens, and bile acids) and exogenous compounds (opioids, non-steroidal anti-inflammatory drugs, and environmental pollutants)...

Evidence suggests that non-domesticated felids inherited the same AB-erythrocyte antigens as domestic cats. To study the possible compatibility of tiger blood with that of other endangered felidae, blood samples from captive tigers and domestic cats were subjected to an in vitro study. The objectives of this study were to (1) identify whether the captive tigers had blood type AB and (2) determine the compatibility between the blood of captive tigers and that of domestic cats with a similar blood type. The anti-coagulated blood with ethylenediaminetetraacetic acid of 30 tigers was examined to determine blood type, and a crossmatching test was performed between tiger and cat blood...

Extant Feliformia species are one of the most diverse radiations of Carnivora (~123 species). Despite substantial recent interest in their conservation, diversification, and systematic study, no previous phylogeny contains a comprehensive species set, and no biogeography of this group is available. Here, we present a phylogenetic estimate for Feliformia with a comprehensive species set and establish a historical biogeography based on mitochondrial DNA. Both the Bayesian and maximum likelihood phylogeny for Feliformia are elucidated in our analyses and are strongly consistent with many groups recognized in previous studies...
