Dermatophytes and skin mycoflora in horse

말의 피부사상균증 및 피부 mycoflora에 관한 연구

This study was carried out to determine the causative agent of dermatophytosis in 7 horses, and to examine the skin mycofloras on 84 healthy and 7 diseased horses which were derived from Jae-ju and Kyonggi, Korea in 1994~1995. Specimens of hair and scale were collected from skin lesions(or normal skins) and inoculated directly on potato dextrose agar and mycobiotic agar. These agar plates were incubated at $25^{\circ}C$ for 2 weeks. Growing fungi were isolated and identified by the morphological and nutritional characteristics. Lesions were found on the hind legs of an infected horses and each lesion was round or oval(1~4 cm) in shape accompanied by severe itching. The causative agent of the 7 equine dermatophytosis was identified as Trichophyton equinum. The skin mycofloras were Penicillium(69.0%), Aspergillus(63.2%), Cladosporium(51.7%), Fusarium(31.0%), Mucor(28.7%), Absidia(18.4%), Alternaria(17.2%), Acremonium(11.5%), Paecilomyces and Phycomyces(6.9%), Rhizopus(5.6%), Trichoderma(4.6%), Scopulariopsis and Trichophyton(3.5%), Beauveria(2.3%), Tritiracheum, Sporothrix, Curvularla, Aureobasidium and Chaetomium(1.2%), and Yeast(27.6%).
