This review covers the available literature on the mycoses of animals in Australia since the last review published in 1967. Of the cutaneous infections, dermatophytoses have been recorded in a wide range of animals: cattle, horses, goats, pigs, sheep, cats, dogs, mice, guinea-pigs, rabbits, a lion, kangaroos, a camel, koalas and wallabies. These infections were caused by several species and varieties of the genera, Microsporum and Trichophyton. Eight agents of ringworms have been recorded in the horse. Two subcutaneous mycoses, phaeohyphomycosis and sporotrichosis have been reported. Phaeohyphomycosis is becoming more common but sporotrichosis is rare having been recorded only once in a cat. The following systemic mycoses have been recorded: adiaspiromycosis, aspergillosis, candidiasis, cryptococcosis, dactylariosis, fusariomycosis, histoplasmosis, miscellaneous mycoses, mycotic abortion and related conditions, zygomycosis, pythiosis, protothecosis and green algal infections. Cryptococcosis has affected 11 different animal species. Mycotic abortion is a serious disease in Victoria. Pythiosis of horses has been extensively studied in northern Australia.

Nucleotide sequences of bovine papillomavirus (BPV) DNA amplified by the polymerase chain reaction (PCR) from samples of equine sarcoid skin tumours were determined. All naturally occurring sarcoids (n = 58 tumours from 32 horses and 2 donkeys) contained BPV-DNA. All but 3 of the genome fragments belonged to the BPV type 1 strain (BPV-1); the remaining were BPV type 2. Similar results were obtained with cutaneous bovine papillomas used as controls (n = 20). One of the horses, carrying 2 sarcoids, was particularly interesting; one tumour contained BPV-1 DNA whilst the other sarcoid yielded BPV-2 DNA, suggesting that horses are not immune to super-infection. BPV-DNA was even amplified from the sarcoid samples which had yielded negative results in previous investigations when DNA isolated from the lesions was used in Southern blot hybridization with BPV probes. In addition, there was no detectable BPV-DNA in any equine or bovine tissue examined other than sarcoids or cutaneous bovine papillomas. Biopsies of normal skin surrounding lesions yielded exclusively negative results. The described nucleotide differences represent a natural genomic variation of this BPV type between geographically distant locations. The identical variations recovered from cattle and horses in Switzerland, a finding of great epidemiological interest, strongly suggest that a uniform variant of BPV-1 is one of the etiologic agents of equine sarcoid and bovine papilloma in a given region.

or angiosarcomas. This is a report of a case of vertebral angiosarcoma in a horse.An 18-year-old Quarter Horse gelding had difficulty lifting his head. Over a 2-week period, the condition progressed to ataxia and recumbency. A myelogram revealed a space-occupying lesion impinging on the spinal cord at the level of the fourth cervical vertebra (C 4 ). The horse was euthanized, and a necropsy was performed.A 3.4-x 0.5-x 0.5-cm dark red and yellow mottled soft mass was free in the extradural space, ventral to the spinal cord, and within the vertebral canal of C 4 (Fig. 1). In a longitudinal section of C 4 , the periosteum of the ventral vertebral
