Blastomyces dermatitidis is a common etiologic agent of fungal pneumonia in dogs. Definitive diagnosis is based on cytologic demonstration of the organism in affected tissues. Fluid obtained through transtracheal aspiration has previously been reported to have a low diagnostic yield for B. dermatitidis organisms. This retrospective study identified B. dermatitidis organisms in 76% of samples when transtracheal aspiration was performed in 17 nonsedated dogs with pulmonary blastomycosis. Transtracheal aspiration is a noninvasive and simple procedure that should be considered as an early diagnostic test whenever blastomycosis is a differential diagnosis in dogs with pulmonary disease.
皮炎芽生菌是犬真菌性肺炎的常见病原体。确诊基于在受影响组织中对该病原体进行细胞学鉴定。此前有报道称，经气管抽吸获得的液体对皮炎芽生菌病原体的诊断阳性率较低。这项回顾性研究发现，在17只未镇静的患有肺芽生菌病的犬中进行经气管抽吸时，76%的样本中检测到了皮炎芽生菌病原体。经气管抽吸是一种无创且简单的操作，当肺芽生菌病是患有肺部疾病犬的鉴别诊断之一时，应将其视为一种早期诊断测试。
