A mycological survey of the crops of approximately 100 healthy birds from each of 6 grow-out operations revealed that the incidence of Candida in the crops ranged from 17.4 to 51.5% with a mean value of 32.3%. The population of Candida in the crops of birds found positive was of low magnitude in the majority of the chickens examined. Of the 573 birds examined in this study less than 1% exhibited visible lesions attributable to Candida. C. albicans comprised 95% of the isolates while C. ravautii, C. salmonicola, C. gulliermondi, C. papapsilosis, C. catenulata and C. brumptii comprised the remainder. The incidence and number of Candida in the crop was related apparently to management practices on the farm. The crops from four field outbreaks of crop mycosis were also studied. Three of the four cases of crop mycosis were characterized by multiple strains of C. albicans in the crop. In one case, C. parapsilosis also was isolated from the crop.
对来自6个育成场、每个场约100只健康家禽嗉囊进行的真菌学调查显示，嗉囊中念珠菌的感染率在17.4%至51.5%之间，平均值为32.3%。在大多数接受检查的鸡中，嗉囊中念珠菌的数量较少。在本研究检查的573只家禽中，不到1%出现了可归因于念珠菌的可见病变。白色念珠菌占分离菌株的95%，而拉氏念珠菌、鲑鱼念珠菌、季也蒙念珠菌、近平滑念珠菌、链状念珠菌和布鲁普念珠菌占其余部分。嗉囊中念珠菌的感染率和数量显然与农场的管理方式有关。还对4起嗉囊真菌病田间疫情的嗉囊进行了研究。4例嗉囊真菌病中有3例的特征是嗉囊中存在多种白色念珠菌菌株。在1例中，也从嗉囊中分离出近平滑念珠菌。
