Minute coccobacilliform bodies have regularly been found in the nasal exudate of fowl infected both by injection and by contact with the coryza of slow onset. These bodies are commonly less than 0.5micro in diameter and are predominantly extracellular. They have consistently failed to grow in artificial media. They are held back by Berkefeld V filters which are impermeable to Hemophilus gallinarum but may pass through filters which are permeable to the test organism. The coccoid bodies are morphologically similar to a cultivable non-infective bacterium which may occasionally be isolated from exudate of the infected fowls.
在通过注射和接触潜伏期慢鼻卡他感染的禽类的鼻腔分泌物中,都曾经常规发现微小的短杆菌样小体。这些小体通常直径小于 0.5μm,主要存在于细胞外。它们在人工培养基中始终无法生长。它们被 Berkefeld V 过滤器截留,该过滤器对禽嗜血杆菌不可渗透,但可以通过对测试生物体可渗透的过滤器。球形小体在形态上类似于一种可培养的非感染性细菌,这种细菌偶尔可从受感染禽类的渗出物中分离出来。
