  Title Feline panleukopena virus and subsequent canine-distemper virus infection in two snow leopards (Panthera uncia) Type Journal Article
  Year 1989 Publication Journal of Zoo and Wildlife Medicine Abbreviated Journal  
  Volume 20 Issue 3 Pages 273-281  
  Keywords diagnosis; fecal; Fpv; leukemia; panleukopenia; panthera uncia; snow leopard; therapy; vaccination; veterinary; Virus; zoo  
  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.

  Title Behavior in adult pairs of captive snow leopards (Panthera uncia) Type Journal Article
  Year 1983 Publication Zoo Biology Abbreviated Journal  
  Volume 2 Issue 1 Pages 1-22  
  Keywords behavior; zoo; zoos; captive; captivity; estrus; breeding; mating; veterinary; browse; 1600  
  Abstract Eight adult pairs of snow leopards (Panthera uncia) were observed for one to three years in the months December through March to determine the species' social and reproductive characteristics in captivity. To statistically examine the occurrence of behaviors as a function of estrus, the observation weeks were divided into three time blocks: before estrus, estrus, and after estrus. Using percentage of scan samples as an estimate of time spent in various behaviors, 16 behaviors and combined behavior categories were examined for (1) behaviors that differentiated successfully from unsuccessfully breeding pairs, (2) sex differences in behavior, (3) significant correlations between pair members, and (4) behaviors that showed time block effects. The rationale for identifying a behavioral profile of successful breeders in snow leopards was to aid zoos in their captive management programs by increasing their knowledge of the social behavior of this species. By finding correlates to breeding success, informed decisions on whether to change partners after a certain period of time, how to group the cats, and the optimum strategy for a survival plan can be made.

  Title Non-invasive monitoring of ovarian function in several felid species by measurement of fecal estradiol-17-beta and progestins Type Journal Article
  Year 1995 Publication Zoo Biology Abbreviated Journal  
  Volume 14 Issue 3 Pages 223-237  
  Keywords Artificial-Breeding-Program; captive-management; Estradiol-17beta; Pregnancy; Progesterone; Progestin; sexual-behavior; genetics; zoo; medicine; veterinary; snow-leopard; feces; fecal-analysis; snow leopard; artificial; breeding; program; captive; management; Estradiol; 17beta; sexual; behavior; browse; snow; leopard; fecal; analysis; 1390  
  Abstract An extraction and assay procedure to measure fecal estradiol-17-beta and progestin concentrations in several cat species was developed and validated for use for noninvasive monitoring of ovarian function. Fecal samples were collected over a range of 3-20 months from female tigers (three), lions (three), snow leopards (three), cheetahs (two), caracals (two), and domestic cats (five). Samples were extracted with 90% methanol, lipids removed with petroleum ether, and the estradiol and progestins in the methanol measured by radioimmunoassay (RIA). High Performance Liquid Chromatography (HPLC) fractionation and subsequent RIA of the fractions indicated that the estradiol-17-beta antiserum cross-reacted primarily with estradiol-17-beta in the feces of lions and tigers and was assumed to be specific for estradiol-17-beta in the feces of other species as well. However, there were several immunoreactive compounds, presumably progesterone metabolites, excreted in the feces which varied both quantitatively and qualitatively among species. The behavior of tigers, lions, cheetahs, and caracals was visually monitored during the collection period and frequency of sexual behaviors was positively correlated with increases in fecal estradiol in all species observed. The mean fecal estradiol-17-beta peaks were as follows: tigers, 128.0 +- 13.1; lions, 186.0 +- 14.8; snow leopards, 136.7 +- 15.9; cheetahs, 140.9 +- 9.0; caracals, 24.5 +- 4.0; and domestic cats 158.9 +- 19.3 ng/gm. Fecal progestin concentrations rose significantly (P lt 0,001) only after breeding or during pregnancy and were as follows: tigers, 5.6 +- 0.6; lions, 1.9 +- 0.1; cheetahs, 8.4 +- 1.1; and caracals, 2.4 +- 0.4 mu-g/gm. Fecal progestins were elevated for one-half to two-thirds of the gestation length during presumed pseudopregnancy but remained elevated throughout successful pregnancies. These results suggest that ovarian function can be monitored noninvasively in the family Felidae by the measurement of fecal estradiol-17-beta and progestin concentrations.

  Title Animal behavior concerns & solutions: snow leopard (Uncia uncia) evaluation, zoo Type Journal Article
  Year 1998 Publication Anim.Keepers' Forum Abbreviated Journal  
  Volume 25 Issue 2 Pages 56-58  
  Keywords aggressive-behavior; behavior; captive-animal-care; diets; endangered; threatened-species; genetics; handling-methods; intraspecies-relationships; social-behavior; husbandry; zoos; snow leopard; aggressive; captive; Animal; care; threatened; species; handling; methods; intraspecies; relationships; social; browse; 1310  
  Abstract The author offers advice on how a captive-raised snow leopard cub could be acclimated to humans so it could be used as a zoo “ambassador”. The cub had negative experiences with humans and lacked socialization with other animals and conspecifics. Methods of avoiding and redirecting the cub's aggressive behavior are suggested. lgh.
