Investigations in New Zealand have shown that animals are an important reservoir of human ringworm. Of 4,328 dermatophytes recovered from human lesions over the six-year period 1963-68, 1,579 (36-5%) were considered to be of animal origin-1,254 (29-0% total) Microsporum canis; 189 (4-4% total) Trichophyton erinacei; 86 (2-0'/r total) Trichophyton mentagrophytes; 46 (1'1%) Trichophyton verrucosum; 2 Microsporum distortum and 2 Trichophyton equinum var. autotrophicum. Human infection with zoophilic dermatophytes was more pronounced in the younger age groups, showed no marked sex distribution, and usually occurred at only a single exposed site on the body. Apart from the M. canis ringworms which occurred mainly between the months February to August (autumn, winter), no marked seasonal variations were observed.Of the 12 dermatophyte species recovered from 1,290 wild, domestic and laboratory animals examined between 1960-68, only nine were regarded as possessing parasitic properties. These were the zoophilic Microsporum canis, M. distortum, M. nanum, Trichophyton erinacei, T. equinum var. autotrophicum, T. gallinae, T. mentagrophytes, T. verrucosum, and the geophilic M. gypseum. Those regarded as essentially non-pathogenic were the geophilic M. cookei, T. ajelloi and T. terrestre. Apart from T. mentagrophytes which was recovered from a wide variety of animals, the remaining pathogenic dermatophytes displayed marked host specificities. T. mentagrophytes var. quinckeanum was not isolated from any of the human or animal specimens.It is confirmed that, in New Zealand, animals form an important reservoir of human ringworm. Direct contact with small domestic pets rather than larger farm animals is the main source of ir>fection. Of the small wild animals, hedgehogs (Erinaceus europaeus) appear most important.Senior Lecturer in Microbiology, University o£ Otago,

Ahstract. Five million spores of a pathogenic isolate of Mortierellu wolfii, when inoculated intravenously into pregnant and nonpregnant cows, caused an acute mycotic pneumonia that resulted in death in less than 4 days. Doses of between 2.5 x lo3 and 1 x lo5 spores injected intravenously caused niycotic abortion in 16-34 days at 6-8 months of pregnancy. Doses of this order also caused focal, nonfatal pneumonia. Acute mycotic pneumonia was also induced in 6-month-old calves by intravenous injections of spores.Intratracheal Acute bovine inycotic pneumonia [S], placentitis leading to abortion [4], and systemic mycosis of adult and neonatal cattle [6, 71 have been reported from this laboratory. Species of Aspergillus, Absidia, Penicillium and iMucor were isolated from some of the material examined i n those studies and were assumed to have caused the lesions. Since 1967, however, M . wolJi has been isolated i n many spontaneous cases of mycotic abortion and pneumonia [9] and evidence for its importance in these diseases in cattle has been presented [2]. This paper presents evidence of the importance of M. wolJi in bovine mycotic pneumonia and placentitis as observed i n this laboratory.Mortievella spp. have been isolated from acutely inflamed placentae and lungs of cattle [2,12,15,16, 18, 201 as well as from hepatic lesions in the bovine fetus [2,[17][18][19]. Mortierella spp. have also been isolated in phycomycoses of man and animals [lo], from tracheal lesions in chickens, from the lungs of a buzzard [14], and from horses with granular dermatitis [l]. Reports of Morfievella infections are very few, however, in comparison with those of other fungi.

“…tonsurans, and 7-. violaceum (Dvorak & Ot~enfigek, 1964) have been listed as recovered from horses but details of these isolations are not available. Of the supposediy non-pathogenic geophilic dermatophytes, 2 have been isolated from horse hair; M. cookei, from an apparently normal animal (Smith, 1968), and Trichophyton (as Keratinomyces) ajeUoi (Rieth & El-FiN, 1959;Pier & Hughes, 1961). In the case of 7-. ajelloi there was some indication that the fungus was responsible for ringworm-like lesions.…”
