Abstract: This dissertation presents studies on the use of medetomidine, ketamine, and atipamezole for sedating and immobilizing mammals in captivity. The species studies were markhor (Capra falconeri megaceros), snow leopard (Panthera uncia), and blue fox (Alopex lagopus). The objectives of the study were to investigate the effects of the drugs, to compare the efficacy of the drugs, and to establish useful dose levels. Tables, charts, and graphs complement the text. Six papers on which the thesis is based are appended.

The prevalence of rodent-borne zoonotic pathogens in the South Gobi desert region of Mongolia. Infection Ecology & Epidemiology, 13(2270258), 1–10.
Abstract: The alpine ecosystems and communities of central Asia are currently undergoing large-scale ecological and socio-ecological changes likely to affect wildlife-livestock-human disease interactions and zoonosis transmission risk. However, relatively little is known about the prevalence of pathogens in this region. Between 2012 and 2015 we screened 142 rodents in Mongolia’s Gobi desert for exposure to important zoonotic and livestock pathogens. Rodent seroprevalence to Leptospira spp. was>1/3 of tested animals, Toxoplasma gondii and Coxiella burnetii approximately 1/8 animals, and the hantaviruses being between 1/20 (Puumala-like hantavirus) and<1/100 (Seoul-like hantavirus). Gerbils trapped inside local dwellings were one of the species seropositive to Puumala-like hantavirus, suggesting a potential zoonotic transmission pathway. Seventeen genera of zoonotic bacteria were also detected in the faeces and ticks collected from these rodents, with one tick testing positive to Yersinia. Our study helps provide baseline patterns of disease prevalence needed to infer potential transmission between source and target populations in this region, and to help shift the focus of epidemiological research towards understanding disease transmission among species and proactive disease mitigation strategies within a broader One Health framework.

Health and zoonotic Infections of snow leopards Panthera unica in the South Gobi desert of Mongolia. Infection Ecology & Epidemiology, 9(1604063), 1–11.
Abstract: Background: Snow leopards, Panthera uncia, are a threatened apex predator, scattered across the mountains of Central and South Asia. Disease threats to wild snow leopards have not been investigated.
Methods and Results: Between 2008 and 2015, twenty snow leopards in the South Gobi desert of Mongolia were captured and immobilised for health screening and radio-collaring. Blood samples and external parasites were collected for pathogen analyses using enzyme- linked immunosorbent assay (ELISA), microscopic agglutination test (MAT), and next- generation sequencing (NGS) techniques. The animals showed no clinical signs of disease, however, serum antibodies to significant zoonotic pathogens were detected. These patho- gens included, Coxiella burnetii, (25% prevalence), Leptospira spp., (20%), and Toxoplasma gondii (20%). Ticks collected from snow leopards contained potentially zoonotic bacteria from the genera Bacillus, Bacteroides, Campylobacter, Coxiella, Rickettsia, Staphylococcus and Streptococcus.
Conclusions: The zoonotic pathogens identified in this study, in the short-term did not appear to cause illness in the snow leopards, but have caused illness in other wild felids. Therefore, surveillance for pathogens should be implemented to monitor for potential longer- term disease impacts on this snow leopard population.

Abstract: Two adult snow leopards (Panthera uncia), male and female, both with vaccinations current, became infected with feline panleukopenia virus (FPV) at the Blank Park Zoo, Des Moines, Iowa, in late 1988. Clinical signs included weakness, hemorrhagic feces, fever, seizures, and nasal discharge. Blood analysis revealed severe lymphopenia and mild anemia. A positive enzyme-linked immunosorbent assay (ELISA) test for FPV on fecal contents from the male leopard confirmed the diagnosis. In spite of intensive therapy, both animals died. Necropsy of the female, which survived for 1 wk after onset of signs, revealed intestinal crypt necrosis, pulmonary consolidation, necrotizing laryngitis, and diffuse lymphoid depletion. The male leopard, which lived 3 wk after onset of illness, had similar enteric and lymphoid lesions. In addition, there was a severe interstitial pneumonia, with syncytial cells containing eosinophilic intracytoplasmic inclusion bodies. Ultrastructural characteristics of these inclusions featured tubular structures consistent with a paramyxovirus. Although repeated virus isolation attempts from the affected lung were negative, polyclonal and monoclonal fluorescent antibody tests were strongly positive for canine distemper virus (CDV). Frozen paired sera from each leopard demonstrated very high acute and convalescing titers to FPV; both animals also seroconverted to CDV, with titers in the male leopard higher than those in the female. Additional tests for toxoplasmosis, feline infectious peritonitis, feline rhinotracheitis, feline calicivirus, feline leukemia, canine parainfluenza, and bovine respiratory syncytial virus were all negative. The neurologic signs present in these leopards remained unexplained, but may have been attributable to CDV infection. A feral cat trapped on zoo property had feces positive for FPV by ELISA. Although the specific contributions of FPV and CDV toward the development of this case are unknown, it is likely that initial FPV-induced immunosuppression allowed the subsequent development of CDV in these snow leopards. The likelihood that initial FPV infection came from feral cats underscores the importance of feral animal control on zoo premises.
