Abstract

This work was planned to investigate the causative fungal agents of dermatophytosis and the rate of distribution of disease among animals in El-Bieda-Libya. 185 samples of skin infection were collected from different animals (75 camels, 62 cattle, 35 sheep and goats, 10 dogs and 3 cats). These animals were clinically diagnosed as dermatophytosis. Results of the microscopical examination of 185 hair and scabs samples revealed the presence of characteristics arthrospores in 165 samples with incidence of (89.2%). On the other hand, results of cultivated samples on specific media showed that 85 were positive culture with incidence of (45.9%). Wide varieties of dermatophytes were isolated from animals, but few zoophilic species were responsible for the majority of the cases. Our finding revealed the identification of two genus: Genus Microsporum, where 7 (8.2%) strains of M. canis were isolated and Genus Trichophyton 78 (91.8%) strains, which include 57 (67.1%) strains of T. verrucosum and 21 (24.7%) strains of T. mentagrophytes. In addition to many fungal contaminant were isolated, the most prevalent were Aspergillus, Penicillum and Alternaria species. Pathogenicity of isolated dermatophytes were tested in rabbits, with application of treatment using methanol extracts of Thymus capitatus. Thymus capitatus was effective in treatment of the infected rabbits.
