【摘要】 用着色芽生菌病患者皮损内的脓液污染活树皮、腐木、锯末、麦秆、沙土和黄土，可见皮损内的着色芽生菌厚壁孢子能在上述物质中很快转成菌丝相，并可与多种杂菌共生。从中分离出卡氏枝抱霉纯培养，污染后第２８天分离阳性率达５２．２％。结果提示着色芽生菌病患者排出体外的病原菌能污染环境，这种污染作用是造成此病地区性流行的原因之一。更多还原

【Abstract】 We used pus with sclerotic cells of fungi from lesion of the patients with chromoblastomycosis due to Cladosporium carrionii to pollute bark, rotten wood, saw dust, straw, sandy--soil and loess. We found that the sclerotic cells may rapidly transform into saprophytic form on the samples.It is a mold and grows well, The symbiosis of the organism and another saprophytic fungi was seen also. Cladosporium carrionii was isolated from 26 (54. 2 % )samples after 28 days. The results suggest that natural environment may be contaminated by the pathogens which were eliminated from lesions of patients with chromoblastomycosis. The contamination is related to endemicity of the disease.更多还原
