Pathology of the female reproductive tract in the koala, Phascolarctos cinereus (Goldfuss), from Victoria, Australia.

Lesions occurred in the female genital tract of 10 of 16 (63%) koalas, Phascolarctos cinereus, examined in Victoria. Inflammation of the uterine horns was seen in all 10 affected koalas; six of these had vaginitis and eight also had salpingitis. Cystic dilation of the ovarian bursa, occasionally with hydrosalpinx, was seen in six koalas with concurrent inflammatory lesions of the lower tract. Cystic lesions were considered to have developed as chronic sequelae to previous inflammation in the ovarian bursa. Lesions were not found in the ovaries. Lesions in the urinary tract lesions were noted in four koalas with genital tract pathology. The significance of these findings in relation to the reproductive success of the koala population on Phillip Island is discussed.

Candidiasis in young hand-reared kangaroos.

Necropsies conducted on four young eastern grey kangaroos (Macropus giganteus) revealed white encrustations adherent to the mucosa of the lips, gums, tongue and oesophagus. The non-glandular stomach was impacted with similar white curd-like material, much of which was ahderent to the mucosa. Histopathology revealed fungal mycelia and blastospores invading the stratified squamous epithelium resulting in focal erosion, ulceration and venous thrombosis. A predominantly neutrophilic leucocytic infiltration was produced in intra-epithelial and submucosal tissues. Candida albicans was isolated from the upper alimentary tract lesions of all cases. Failure to thrive on milk diets, prolonged episodes of diarrhoea and antibiotic therapy during hand-rearing were considered to be significant predisposing factors to infection.

Mortality in little penguins (Eudyptula minor) along the coast of Victoria, Australia.

Forty-eight little penguins (Eudyptula minor) consisting of 21 (43.7%) mature, 18 (37.5%) juvenile and nine (18.7%) of undetermined age, from 10 Victorian coastal localities were examined during 1977-78. Thirty-seven (77%) of all penguins were in poor body condition with moderate to heavy burdens of internal and external parasites. Acute parasitic gastric ulceration with accompanying hemorrhage, was implicated in the death of four birds. Chronic gastric ulcers were thought to have caused appetite depression and starvation in 28 birds. Other significant lesions encountered included renal coccidiosis, parasitic cholangiohepatitis and pulmonary aspergillosis. It is suggested that the increased mortality experienced during 1977-78 was due to starvation or to exacerbation of the effects of existing parasite burdens on starving and exhausted birds.

Foreign body perforation of the esophagus initiating traumatic pericarditis in an Australian fur seal.

Postmortem examination of a juvenile Australian fur seal, Arctocephalus pusillus doriferus, washed ashore on Philip Island, Victoria, revealed traumatic fibrinous pericarditis and hemothorax. A foreign body lodged in the right ventricle was identified as the barbed spine of the ray Urolophus paucimaculatus. A small puncture wound through the esophagus indicated the initial perforation site.
