Abstract: Objective: To determine the species and distribution characteristics of pathogenic bacteria of skin superficial mycosis in our hospital. Methods: The data of patients who were positive for fungal under microscopy, and performed pathogen isolation, culture and strain identification in our hospital from May 2014 to May 2024 were retrospectively analyzed. Results: A total of 10 492 patients were analyzed, of whom 4757 strains were positive, and the top three were Trichophyton rubrum 1864 (39.18%), Candida albicans 264 (5.55%) and Yeastlike bacteria 159 (3.34%). The infection rates of Candida albicans, Yeastlike bacteria, Candida tropicalis and Trichophyton mentophyta were higher in females than in males (Ps<0.05), and the infection rate of Epidermophyton flocculus was higher in males than in females (P<0.05). The top three diseases were onychomycosis (2482 cases, 52.18%), tinea pedis (911 cases, 19.15%) and tinea manuum (540 cases, 11.35%). The prevalence of onychomycosis was higher in females than in males (χ2=192.68, P<0.01). The prevalence of tinea of the body, tinea of the hand, tinea of the thigh was higher in males than in females (Ps<0.01). Conclusion: In our hospital, the main fungal infection diseases were onychomycosis, tinea pedis and tinea manuum. The main pathogenic fungi were Trichophyton rubrum, Candida albicans and Yeastlike bacteria. There is a certain relationship between the species of disease, bacteria and sex.
