Abstract: In work over a period of 8 years, dermatophytes were recovered from 12 animal species in the North Island of New Zealand. A total of 552 dermatophytes were isolated and belonged to the Microsporum (6 species) and Trichophyton (6 species) genera. Some unusual isolations are reported: Microsporum canis and Trichophyton mentagrophytes var. mentagrophytes were recovered from calves; Microsporum distortum from a dog, which was the first known isolation from an animal in the North Island; four horses, from the same stable, yielded Microsporum equinum which has not previously been recorded in this country; Trichophyton erinacei was recovered from lesions on a cat which is the first report of the dermatophyte from an animal other than the dog, hedgehog or man; Trichophyton equinum var. autotrophicum was a rare isolation from a dog. Species affinity was demonstrated with the dermatophytes M. canis; M. nanum; M. equinum; T. equinum; and T. verrucosum. These zoophilic species appear to be passed between individuals of the same species, with occasional infection in man and other animal species. T. mentagrophytes var. mentagrophytes had a wider distribution, being isolated from dogs, cats, guinea-pigs and rats. The infection in rats was subclinical. The geophilic species M. cookei, T. ajelloi and T. terrestre were recorded but not regarded as being pathogenic. M. gypseum was significant in cases involving dogs, horses and a cat, as arthrospores were seen invading the affected hairs.
