目前芽生菌病波及的范围很广,原发感染的常见部位为肺部,但播散性肺外感染亦可发生。虽然致敏作用的准确率因缺乏令人满意的皮肤试验尚难确定,但接触皮炎芽生菌者多数可被致敏而无临床症状。多数病例为散发性,但亦有成批发病者。皮炎芽生菌的理想环境似是 pH 酸性、污染动物排泄物的潮湿土壤,其最适宜的生态环境是接近河流及溪流的地区,特别是易受到河水泛滥的地方,例如河堤等处。除北美外,很少注意到皮炎芽生菌的来源,在某些病例中,认为愿染是接触了某些污染物质(如从美国进口的棉花)的传染性颗粒所致,这一机制只能解释极少数病例,而大多数是由于直接接触了 At present, blastomycosis affects a wide range of areas, the common part of the primary infection of the lungs, but disseminated extrapulmonary infection can occur. Although the accuracy of sensitization is difficult to determine due to the lack of a satisfactory skin test, the majority of dermatophytes exposed to dermatitis can be sensitized without clinical symptoms. Most cases are sporadic, but there are also groups of patients. The ideal environment for dermatitis budding bacteria is acidic and polluted wet soil of animal waste. The most suitable ecological environment is close to rivers and streams, especially those prone to river flooding, such as riverbanks. With the exception of North America, where Dermatitis dermatitidis is rarely noted, and in some cases grittasis is thought to be caused by infectious particles exposed to certain pollutants (such as cotton imported from the United States), this mechanism can only Very few cases are explained, most of them due to direct contact
