[Urban cycles of zoonotic mycoses]

Based on their own results assembled during mycological examinations of 9958 subjects, 5496 animals and 648 specimens of non-animal substrates, and using data from the literature, the authors tried to formulate general laws concerning the prevalence of causal agents of mycoses with a zoonotic character which circulate steadily in urban areas: Microsporum canis, M. persicolor, Trichophyton mentagrophytes, M. equinum and T. equinum, T. verrucosum, some geophilic dermatophytes, Cryptococcus neoformans and Emmonsia crescens. In the characteristics of different urban cycles they used as a basis the evaluation of the prevalence of reservoir animals and reservoir substrates on the territory of towns and the evaluation of the most frequent routes of transmission of the agents from extrahuman sources to man. Preventive provisions leading to a reduction of the risk of the disease in humans must be specific with regard to different urban cycles.
