Sublingual papillomas of cheetahs in southern Africa.

Nine distinct papillomaviruses (Lambdapapillomavirus) have been described in domestic and nondomestic cats, but not in cheetahs. These viruses have been associated with cutaneous papillomas or plaques, bowenoid in situ carcinomas, feline cutaneous squamous cell carcinomas (SCC), feline sarcoids, and oral (often sublingual) papillomas. Fourteen cheetahs from the AfriCat foundation (Namibia) and one from the Ann van Dyk Cheetah center (South Africa) presented with sublingual lesions reminiscent of sublingual papillomas. Two animals were biopsied and the histopathology revealed benign proliferative epithelial lesions with prominent thickening of the overlying squamous epithelium. Throughout the squamous epithelial layers were cells with nuclear enlargement, irregularity of the nuclear membranes and cell contours, focal hyperchromasia of the nuclei, and perinuclear halos, reminiscent of a virus-associated process as seen in papillomavirus infections. Thirteen more cheetahs were sampled and the tissue snap frozen for molecular characterization. Amplification and sequencing of the papillomavirus L1, E6, E7, and E1 gene regions was achieved with modified primers. Maximum likelihood phylogenetic analyses revealed all 15 cheetah papilloma samples were 99.99% genetically similar and closely related to, but genetically distinct from any known felinepapillomaviruses. All cheetahs were FIV and FeLV negative. The results suggest the samples identified in this study can be considered a previously undescribed or novel feline papillomavirus and the authors propose "Acinonyx jubatus papillomavirus type 1" (AjPV-1), within the Lambdapapillomavirus 1 genus (Family: Papillomaviridae).

Interspecific hybridization between greater kudu and nyala.

Hybridization of wildlife species, even in the absence of introgression, is of concern due to wasted reproductive effort and a reduction in productivity. In this study we detail an accidental mating between a female nyala (Tragelaphus angasii) and a male greater kudu (T. strepsiceros). The hybrid was phenotypically nyala and was identified as such based on mitochondrial DNA. Further genetic analysis based on nine microsatellite markers, chromosome number and chromosome morphology however, confirmed its status as an F1 hybrid. Results obtained from a reproductive potential assessment indicated that this animal does not have the potential to breed successfully and can be considered as sterile.

Unilateral tongue swelling: an unusual presentation of angiotensin-converting enzyme inhibitor-related angioedema.

Angioedema is a rare but potentially fatal complication of angiotensin-converting enzyme inhibitor (ACEi) treatment. This class of drugs is widely used in the treatment of hypertension, cardiac failure and other common conditions.This case report discusses a male patient in his 60s who presented with acute swelling of the right side of his tongue, an unusual manifestation of angioedema, which typically involves bilateral swelling of orofacial structures.Accurate and early identification of this complication affords the opportunity for early, potentially life-saving intervention during the acute episode and also cessation of the treatment, reducing the risk of recurrence in the future.This case is one of only a few reported in English language medical literature and the first from Africa, suggesting either rarity or under-reporting. The case contributes to the understanding of ACEi-induced angioedema, particularly in Africa where hypertension is prevalent and ACEi is commonly used.

The complete mitochondrial genome of Gyps coprotheres (Aves, Accipitridae, Accipitriformes): phylogenetic analysis of mitogenome among raptors.

Three species of Old World vultures on the Asian peninsula are slowly recovering from the lethal consequences of diclofenac. At present the reason for species sensitivity to diclofenac is unknown. Furthermore, it has since been demonstrated that other Old World vultures like the Cape (Gyps coprotheres; CGV) and griffon (G. fulvus) vultures are also susceptible to diclofenac toxicity. Oddly, the New World Turkey vulture (Cathartes aura) and pied crow (Corvus albus) are not susceptible to diclofenac toxicity. As a result of the latter, we postulate an evolutionary link to toxicity. As a first step in understanding the susceptibility to diclofenac toxicity, we use the CGV as a model species for phylogenetic evaluations, by comparing the relatedness of various raptor species known to be susceptible, non-susceptible and suspected by their relationship to the Cape vulture mitogenome. This was achieved by next generation sequencing and assembly. The Cape vulture mitogenome had a genome size of 16,908 bp. The mitogenome phylogenetic analysis indicated a close evolutionary relationship between Old World vultures and other members of the Accipitridae as indicated by bootstrap value of 100% on the phylogenetic trees. Based on this, we postulate that the other species could also be sensitive to the toxic effects of diclofenac. This warrants further investigations.

Canine parvovirus detected from a serval (Leptailurus serval) in South Africa.

Canine parvovirus first emerged in domestic dogs (Canis familiaris), most likely as a variant of the feline panleucopaenia virus. Relatively recently, canine parvovirus-2a and canine parvovirus-2b infections have been identified in both symptomatic and asymptomatic domestic cats, while canine parvovirus infections have also been demonstrated in wild felids. This report documents the first known case of canine parvovirus-2b detected in unvaccinated serval (Leptailurus serval) from South Africa. The serval presented with clinical signs of vomiting, anorexia and diarrhoea that responded to symptomatic treatment. Two weeks later, severe leucopaenia, thrombocytopenia and death occurred. Typical enteric histological lesions of parvovirus infection were not observed on histopathological examination of the small intestine; however, histological lesions consistent with septicaemia were present. Canine parvovirus was detected in formalin-fixed paraffin-embedded small intestine using polymerase chain reaction. Phylogenetic analysis of the sequence of the canine parvovirus viral capsid protein gene showed similarities between the sample from the serval and canine parvovirus-2b isolates from domestic dogs in Argentina and South Africa. A case of canine parvovirus-2b in a domestic dog from South Africa in 2012 that fell within the same clade as the serval sample appears distantly related because of the long branch length. The significance of these findings is explored. More extensive surveys of canine parvovirus in domestic and wild felids and canids are needed to understand the epidemiology of canine parvovirus in non-domestic felids in South Africa.

A retrospective study evaluating the efficacy of identification and management of sepsis at a district-level hospital internal medicine department in the Western Cape Province, South Africa, in comparison with the guidelines stipulated in the 2012 Survivi.

BACKGROUND: Currently there is little information on the identification, management and outcomes of patients with sepsis in developing countries. Simple cost-effective measures such as accurate identification of patients with sepsis and early antibiotic administration are achievable targets, within reach without having to make use of unsustainable protocols constructed in developed countries. OBJECTIVES: To assess the ability of clinicians at a district-level hospital to identify and manage sepsis, and to assess patient outcome in terms of in-hospital mortality and length of hospital stay given the above management. METHODS: A retrospective descriptive study design was used, analysing data from the routine burden of disease audit done on a 3-monthly basis at Karl Bremer Hospital (KBH) in the Western Cape Province, South Africa. RESULTS: The total sample size obtained was 70 patients, of whom 18 (25.7%) had an initial triage blood pressure indicative of sepsis-induced hypotension. However, only 1 (5.5%) of these 18 patients received an initial crystalloid fluid bolus of at least 30 mL/kg. The median time that elapsed before administration of antibiotics in septic shock was 4.25 hours. Furthermore, a positive delay in antibiotic administration (p=0.0039) was demonstrated. The data also showed that 8/12 patients (66.7%) with septic shock received inappropriate amounts of fluids. The in-hospital mortality rate for sepsis was 4/24 (16.7%), for severe sepsis 11/34 (32.3%) and for septic shock a staggering 9/12 (75.0%). CONCLUSIONS: The initial classification process and management of sepsis by clinicians at KBH is flawed. This inevitably leads to an increase in in-hospital mortality.

Feline panleukopaenia virus in captive non-domestic felids in South Africa.

An outbreak of feline panleukopaenia virus (FPLV) infection was diagnosed by pathology, electron microscopy and polymerase chain reaction (PCR) in vaccinated captive-bred subadult cheetahs in South Africa. Subsequent to this disease outbreak, 12 cases of FPLV diagnosed on histology were confirmed by PCR in captive African black-footed cat, caracal, cheetah, lion, ocelot and serval. Phylogenetic analyses of the viral capsid protein gene on PCR-positive samples, vaccine and National Center for Biotechnology Information (NCBI) reference strains identified a previously unknown strain of FPLV, present since at least 2006, that differs from both the inactivated and the modified live vaccine strains. A previously described South African strain from domestic cats and cheetahs was identified in a serval. Surveys of FPLV strains in South African felids are needed to determine the geographical and host species distribution of this virus. Since non-domestic species may be reservoirs of parvoviruses, and since these viruses readily change host specificity, the risks of FPLV transmission between captive-bred and free-ranging carnivores and domestic cats and dogs warrant further research.
