Causative agents of tinea capitis isolated from the patients in Hubei province and surrounding area in China during 1960-2015

Abstract

Abstract:

Objective To understand the pathogens of tinea capitis during the period 1960-2015.Methods Fungal strains isolated from the patients with tinea capitis in the Medical Mycology Clinical Laboratory were subjected to a classification and statistical analysis.Morphological, physiological and biochemical methods were applied for fungal identification.Results Tinea capitis prevalence was high in the 1960s, with Trichophyton violaceum (41.9%) and Trichophyton schoenleinii (31.0%) being the most common pathogenic species, while the cases decreased sharply in the 1970s.Later in the 1990s, the proportion of Microsporum canis dropped to 1% after its peak (36.9%).T.violaceum had replaced T.schoenleinii and become the most common species (63%).T.schoenleinii and Trichophyton rubrum tended to infect adults, while T.violaceum, M.canis, Trichophyton interdigitale and Microsporum ferrugineum were more likely to infected children.The proportion of female patients among adults (64.6%) was higher than that of children (50.6%) (T.schoenleinii excluded) (P<0.05).Conclusion The pathogens of tinea capitis changed over time and now T.violaceum had become the most common species in the district.

Key words: tinea capitis, Trichophyton schoenleinii, Trichophyton violaceum, Microsporum canis, Trichophyton interdigitale
