摘要

An epizootic of sudden death in tammar wallabies (Macropus eugenii) was noted within 6 research facilities and zoological gardens within New South Wales between October and December 1998 and in one research facility in Queensland in March 1999. One hundred and twenty tammar wallaby deaths were confirmed during this period. Population censuses conducted in these facilities after the outbreak, however, indicate that approximately 230 tammar wallabies may have died. The majority of animals died without premonitory signs. A small proportion of wallabies exhibited increased respiratory rate, sat with a lowered head shortly before death, or were discovered in lateral recumbency, moribund, with muscle fasciculations. Gross post mortem findings consistently included massive pulmonary congestion, mottled hepatic parenchyma, and subcutaneous edema throughout the hind limbs and inguinal region. Approximately 30% of the animals examined also had extensive hemorrhage within the fascial plains and skeletal muscle of the hind limb adductors, inguinal region, ventral thorax, dorsal cervical region, and peri-renal retroperitoneal area. The tissues of affected animals became autolytic within a short period after death. Microbiologic examination of tissues from 14 animals did not provide any significant findings. Toxicologic examination of the gastric and colonic content of four animals did not reveal evidence of brodifacoume or other rodenticides.
