| Abstract |
A 5-mo-old male snow leopard (Panthera uncia) was presented for mild rear leg lameness. Osteomyelitis was suspected on the basis of radiographic changes and confirmed by histopathology of a biopsy sample from the affected bone. Aerobic cultures of the biopsies repeatedly grew Klebsiella oxytoca. Repeated anaerobic and fungal cultures did not result in growth. The leopard was treated unsuccessfully with cefadroxil, chloramphenicol, and trimethoprim/sulfadiazine despite apparent in vitro sensitivity to these antibiotics. Successful resolution was eventually achieved with enrofloxacin, 7.5 mg/kg p.o. b.i.d. for 60 days. The number of bones involved (right humerus, right and left ulna, right and left radius, right and left femur, right and left tibia, mandible, right metatarsus) made this an unusual presentation of osteomyelitis. |

The structure of the foramen ovale from 16 species representing 4 carnivore families, the Felidae, Canidae, Ursidae and Hyaenidae, was studied using the scanning electron microscope. The Felidae were represented by 9 domestic cat fetuses (Felis catus), 2 snow leopard neonates (Uncia uncia), an ocelot neonate (Leopardus pardalis), 2 lion neonates (Panthera leo), a panther neonate (Panthera pardus) and 3 tigers (Neofelis tigris), comprising 2 fetuses and a neonate. The Canidae were represented by a golden jackal neonate (Canis aureus), a newborn wolf (Canis lupus), 8 domestic dog fetuses (Canis familiaris), 3 red fox neonates (Vulpes vulpes) and a dhole neonate (Cuon alpinus). The Ursidae were represented by a brown bear neonate (Ursus arctos), a day-old grizzly bear cub (Ursus arctos horribilis), a polar bear neonate (Ursus maritimus), and 2 additional bear fetuses (species unknown). The Hyaenidae were represented by a striped hyaena neonate (Hyaena hyaena). In each species, the foramen ovale, when viewed from the terminal part of the caudal vena cava, had the appearance of a short tunnel. A thin fold of tissue, the developed remains of the embryonic septum primum, extended from the distal end of the caudal vena cava for a variable distance into the lumen of the left atrium and contributed towards the 'tunnel' appearance in all specimens. It constituted a large proportion of the tube, and its distal end was straight-edged. There was fibrous material underlying the endothelium of the flap, the apparent morphology of which suggested that it comprised cardiac muscle.(ABSTRACT TRUNCATED AT 250 WORDS) |
