Abstract: Nine small cats, including one bobcat (Felis rufus), one Pallas cat (F. manul), one Canada lynx (F. lynx canadensis), two fishing cats (F. viverrina), two margays (F. wiedii), and two sand cats (F. margarita), necropsied between June 1995 and March 1997 had large numbers of gastric spiral bacteria, whereas five large cats, including one African lion (Panthera leo), two snow leopards (P. uncia), one Siberian tiger (P. tigris altaica), and one jaguar (P. onca), necropsied during the same period had none. All of the spiral organisms from the nine small cats were histologically and ultrastructurally similar. Histologically, the spiral bacteria were 5-14 mum long with five to nine coils per organism and were located both extracellularly within gastric glands and surface mucus, and intracellularly in parietal cells. Spiral bacteria in gastric mucosal scrapings from the Canada lynx, one fishing cat, and the two sand cats were gram negative and had corkscrew-like to tumbling motility when viewed with phase contrast microscopy. The bacteria were 0.5-0.7 mum wide, with a periodicity of 0.65-1.1 mum in all cats. Bipolar sheathed flagella were occasionally observed, and no periplasmic fibrils were seen. The bacteria were extracellular in parietal cell canaliculi and intracellular within parietal cells. Culture of mucosal scrapings from the Canada lynx and sand cats was unsuccessful. Based on morphology, motility, and cellular tropism, the bacteria were probably Helicobacter-like organisms. Although the two margays had moderate lymphoplasmacytic gastritis, the other cats lacked or had only mild gastric lymphoid infiltrates, suggesting that these organisms are either commensals or opportunistic pathogens.

Abstract: Reports that a preliminary project on nursing behavior in 3 young snow leopards revealed 2 phases in suckling pattern: nonnutritive and nutritive. The latter was distinguished by stereotypic rhythmical movements of the ears associated with swallowing. The cubs also demonstrated a teat preference, but the adaptive significance of such preferences and the accompanying agonistic behavior were unclear.

Abstract: Blue sheep (Pseudois nayaur) are the main prey of the endangered snow leopard (Panthera uncia) as well as an important game species in Nepal. A knowledge of how blue sheep utilize their habitat is essential for the scientific management of the sheep and for the conservation of the snow leopard, but we only have a limited understanding of this aspect of blue sheep ecology. I studied the habitat use pattern of blue sheep by direct observation in the Anna-purna Conservation Area, Nepal where they occur sympatrically with the snow leopard. The sheep used grassland habitats more frequently during pre-parturition (spring) and post-parturition (autumn) than other habitat types, but scrub and grassland habitats were used equally frequently during the rut (winter). The sheep used smooth undulating slopes of medium steepness (<40 degrees) on southerly aspects within the elevation range of 4,200-4,600 m most frequently in all seasons, and there was no evidence of seasonal migration along the elevation gradient. When not in broken landforms (e.g., cliff, landslides), the sheep maintained proximity (less than or equal to 150 m) to such features suggesting their importance as escape cover (i.e., from predators). The use of habitat components by blue sheep appeared to be related to the distribution of foraging areas and escape cover.

Abstract: Modified live feline panleukopenia virus (FPLV) vaccine protected dogs against canine parvovirus (CPV) infection. However, unlike the long- lived (greater than or equal to 20-month) immunity engendered by CPV infection, the response of dogs to living FPLV was variable. Doses of FPLV (snow leopard strain) in excess of 10(5.7) TCID50 were necessary for uniform immunization; smaller inocula resulted in decreased success rates. The duration of immunity, as measured by the persistence of hemagglutination-inhibiting antibody, was related to the magnitude of the initial response to vaccination; dogs with vigorous initial responses resisted oronasal CPV challenge exposure 6 months after vaccination, and hemagglutination-inhibiting antibodies persisted in such dogs for greater than 1 year. Limited replication of FPLV in dogs was demonstrated, but unlike CPV, the feline virus did not spread to contact dogs or cats. Adverse reactions were not associated with living FPLV vaccination, and FPLV did not interfere with simultaneous response to attenuated canine distemper virus.

Abstract: This study reports on two series of cases of Mycobacterium bovis infection in zoo animals. The first was in a captive population of baboons (Papio hamadryas) and the second in a mixed group of wild mammals, including four leopards (Panthera uncia and Panthera pardus) and a sea-lion (Otaria byrona). The isolation and identification of strains of M. bovis confirmed the presence of M. bovis infections in both zoos. The epidemiological study using genetic markers such as the IS6110-based DNA fingerprinting system made it possible to differentiate between M. bovis strains. The M. bovis strains isolated from baboons were shown to contain a single IS6110 copy, as usually do cattle isolates, whereas the M. bovis strains isolated from the other exotic animals presented multiple copies. This finding suggests that the origin of the contamination for the baboons in zoo A could be related to cattle. The origin of the contamination for the leopards and sea-lion in zoo B is more difficult to determine. In conclusion, the authors suggest some recommendations for avoiding outbreaks of tuberculosis infections in zoos.
