Tinea capitis (TC) is a common dermatophyte infection primarily affecting children. The causative pathogens belong to two genera: Trichophyton and Microsporum. Although there is great local variation in the epidemiology of TC worldwide, Trichophyton tonsurans is currently the most common cause of TC with Microsporum canis second. M. canis is a zoophilic ectothrix species, and remains the predominant causative organism in many countries in the Mediterranean area. The most important sources of infection of M. canis are cats and dogs, and it is not considered to spread from humans. In our study we evaluated fingertips contamination which may lead to human trasmission of M. canis infection from patients suffering from TC.
