title: Enzymatic activity of Microsporum canis and Trichophyton mentagrophytes from breeding rabbits with and without skin lesions.
abstract: Microsporum canis and Trichophyton mentagrophytes are zoophilic dermatophytes which can cause skin infections in animals and humans. The clinical expression of this infection strongly varies depending on host, fungal species as well as enzyme production. No comparative studies are available on the enzymatic activities of M. canis and T. mentagrophytes isolated from breeding rabbits. Thus, the aim of this work was to assess the capability of M. canis and T. mentagrophytes isolated from rabbits both with and without lesions in producing different enzymes. The relationship of dermatophyte enzymatic activities and presence/absence of skin lesions has also been investigated. A total of 260 isolates of T. mentagrophytes and 25 isolates of M. canis sampled both from healthy and lesioned skin of rabbits, as well as from air samples of positive farms were examined. The results showed that T. mentagrophytes and M. canis from rabbits produce different enzymes. However, only elastase and gelatinase were linked to the appearance of lesions in T. mentagrophytes infections, whereas lipase in those by M. canis.
