Isolation of keratinophilic fungi from floors in Roman primary schools.
Keratinophilic fungi are present in the environment with variable distribution patterns that depend on different factors, one of which, of fundamental importance, is human and or animal presence. The present study was conducted in the environment and classrooms of schools in order to evaluate the relationship between the human presence and the presence of keratinophilic fungi. In order to achieve this goal, a new isolation technique was used. From 20 samples, 253 colonies of keratinophilic fungi were isolated. The results showed that species of the genus Chrysosporium were present in 100% of the samples, while Microsporum and Trichophyton species were present in 40% and 65% of the samples respectively. The percentage of three pathogenic species, M. canis (25), T. mentagrophytes (10) and M. gypseum (10) was significant. The other species isolated were: T. terrestre (55%), Trichophyton sp. (35%), M. cookei (25%) and T. ajelloi (10%). A correlation between the amount of gathered dust and the number of colonies of keratinophilic fungi isolated was not found.
