Analysis of mixed infection in superficial mycoses

Objective To investigate the prevalence and pathogenic fungi species of mixed infection in superficial mycoses in Puyang district. Methods Total 494 specimens of clinically suspected patients with dermatomycoses were examined for causative fungi. The clinical materials of each patient with microscopy positive and/or fungal culrure positive were recorded and analyzed. Results Thirty-six cases were diagnosed mixed infection by dermatophyte and candidia （7.89%）. Tinea cruris （58.33%） and tinea pedis （27.78%） are mostly seen. Seventy-two strains of pathogenic fungi were isolated, in which the most frequently isola- ted dermatophyte was Trichophyton rubrum （75.00%） , the most frequently isolated candida was non- Candida albicans （72. 22% ）. Conclusion In Puyang district, mixed infection in superficial mycoses is increasing, mixed infection by dermatophyte and Candida in tinea cruris and tinea pedis are mostly seen. Trichophyton rubrum is the most frequent pathogen, followed by non- Candida albicans.
