Microsporum equinum. [Descriptions of Fungi and Bacteria].
Abstract A description is provided for Microsporum equinum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of the horse, sometimes transmitted to man. Cats, dogs, guineapigs and rabbits have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). Infected hairs usually fluoresce bright green under Wood's light and show a small-spored ectothrix type of invasion. In horses the lesions cannot be distinguished clinically from those caused by other species. Usually they are dry, raised and scaling and lead to circumscribed, bare patches. They may occur on any part of the animal, but particularly on the saddle and girth regions. In man, infections of the glabrous skin (tinea corporis), particularly of the arms, and of the beard area (tinea barbae) have been reported, the lesions usually being small and erythematous. GEOGRAPHICAL DISTRIBUTION: Africa (Algeria, Congo (from cases of 'Kenya Mange' of horses), Madagascar, Morocco, Sudan), Asia (Iran, Java, U.S.S.R.); Australasia and Oceania (Fiji); Europe (Belgium, Bulgaria, Denmark, France, Germany, Great Britain, (?) Greece, Italy, Netherlands, Norway, Romania, U.S.S.R.); North America (N.J., N.Y.); South America (Uruguay).
