This study was performed to evaluate the diversity and prevalence of yeasts associated with esophageal mycosis in domestic ducks and geese. Fungi were isolated from esophageal lesions of dead animals sent for microbiologic laboratory diagnosis. Species identification using a culture-dependent method was carried out by sequencing of the internal transcribed spacer (ITS)1-5.8S rRNA-ITS2 region. The most frequently isolated yeast was Candida albicans (43.1%) followed by Saccharomyces cerevisiae (17.6%), Candida kefyr (11.7%), Kazachstania bovina (11.7%), Candida lambica (3.9%), and single isolates (1.9%) representing Candida inconspicua, Candida rugosa, Candida pelliculosa, Candida krusei, Magnusiomyces capitatus, and Trichosporon asahii. Our results indicate that a number of potentially pathogenic yeast species can be isolated from esophageal mycosis of waterfowls, but additional studies are needed to make conclusions regarding their possible etiologic role in disease.
本研究旨在评估与水禽食管真菌病相关的酵母菌的多样性和流行情况。从送检微生物实验室诊断的病死动物的食管病变中分离出真菌。通过测序内部转录间隔区（ITS）1-5.8S rRNA-ITS2 区，采用基于培养的方法进行种属鉴定。最常分离到的酵母菌是白色念珠菌（43.1%），其次是酿酒酵母（17.6%）、卡氏酵母（11.7%）、博伊丁假丝酵母（11.7%）、羔羊假丝酵母（3.9%）和单个分离株（1.9%），分别代表近平滑念珠菌、皱褶假丝酵母、皱褶假丝酵母、光滑假丝酵母、马氏被毛孢子菌和阿萨希毛孢子菌。我们的结果表明，从水禽的食管真菌病中可以分离出许多潜在的致病性酵母菌，但需要进一步的研究才能确定它们在疾病中的可能病因作用。
