Severity of ringworm infections appears to be related to the production of proteolytic enzymes which in turn is related to mating type in two species tested T. mentagrophytes (A. benhamii (a) and (A)) and Mierosporun?,fulvum (Nannizzia fulva (+) and (-)). No difference in experimental guinea pig infections could be detected between the mating types of two other species which did not elaborate proteolytic enzymes Nannizzia incurvata and Nannizzia gypsea (Microsporum qypseum complex).
