Marma B.B.and Yunchis V.V. (1968). A contribution to biology of the Snow-leopard (Panthera uncia uncia) (by observations in captivity) (Vol. XLVII, issue 11.).
Abstract: The methods to obtain the progeny of the snow leopard (Panthera uncia uncia) in captivity were being elaborated in the zoological garden of Kaunas, Lithuanian SSR. The blood characteristics for snow leopards is given and compared to that for African lions and Sumatrian tigers. A series of internal, external and clinical indices is established. The rat lasts for 5-7 day, the duration of pregnancy equals 98 days. The duration of lactation varies from 3 to 4 months. Sexual maturity is attained on the 3rd-4th year. From 1960 to 1967 in zoological garden of the world about 29 snow leopards were born, 14 of them in the Kaunas zoological garden.

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.

Graham, L. H., Goodrowe, K. L., Raeside, J. I., & Liptrap, R. M. (1995). Non-invasive monitoring of ovarian function in several felid species by measurement of fecal estradiol-17-beta and progestins. Zoo Biology, 14(3), 223–237.
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.

Wharton, D. (1997). Endangered Species Update. Endangered Species Update, 14(11), 13.
Abstract: The snow leopard is listed as endangered, although most of its high mountain habitat remains untouched. However the ability of humans to exploit wildlife has led to it being endangered. Serious attempts to keep snow leopards in captivity began in 1891, but it was not until the 1950s that cubs survived long enough to become breeders. The American Zoo and Aquarium Association (ASA) Snow Leopard Species Survival Plan (SSP) was set up in 1984, achieving success with breeding goals.

Machado, C., Brown, P., & Turner, R. (1984). Dental crown restorations on a snow leopard. Journal Of Zoo Animal Medicine, 15(4), 146–150.
Abstract: In the spring of 1983 the San Francisco Zoo received a female snow leopard (Panthera uncia) as part of an exotic animal exchange program with the People's Republic of China. Upon examination, it was found that this nine-yea old, seventy-five pound, wild-trapped animal had sustained considerable dental injuries, including fractures of all maxillary and mandibular anterior teeth. The purpose of this paper is to describe the dental procedures undertaken to restore the physiological function of all four canines.

Abstract: The Pallas’s cat (Otocolobus manul) is one of the most understudied taxa in the Felidae family. The species is currently assessed as being of “Least Concern” in the IUCN Red List, but this assessment is based on incomplete data. Additional ecological and genetic information is necessary for the long-term in situ and ex situ conservation of this species. We identified 29 microsatellite loci with sufficient diversity to enable studies into the individual identification, population structure, and phylogeography of Pallas’s cats. These microsatellites were genotyped on six wild Pallas’s cats from the Tibet Autonomous Region and Mongolia and ten cats from a United States zoo-managed population that originated in Russia and Mongolia. Additionally, we examined diversity in a 91 bp segment of the mitochondrial 12S ribosomal RNA (MT-RNR1) locus and a hypoxia-related gene, endothelial PAS domain protein 1 (EPAS1). Based on the microsatellite and MT-RNR1 loci, we established that the Pallas’s cat displays moderate genetic diversity. Intriguingly, we found that the Pallas’s cats had one unique nonsynonymous substitution in EPAS1 not present in snow leopards (Panthera uncia) or domestic cats (Felis catus). The analysis of the zoo-managed population indicated reduced genetic diversity compared to wild individuals. The genetic information from this study is a valuable resource for future research into and the conservation of the Pallas’s cat.
