A condition evidenced by retarded growth of wool with alteration of the yolk into a yellow, sticky, wax-like substance was investigated. The condition was associated with hyperaemia and cellular infiltration into the dermis in the affected areas. Three bacterial species, viz. Enterobacter aerogenes, E. agglomerans and Hafnia alvei, which could grow on the water-extractable component of wool-yolk, were incriminated as the cause of the condition.
对一种以羊毛生长迟缓且羊毛脂变为黄色、粘性、蜡状物质为特征的病症进行了研究。该病症与受影响区域真皮的充血和细胞浸润有关。三种细菌，即产气肠杆菌、聚团肠杆菌和蜂房哈夫尼亚菌，被认为是导致该病症的原因，它们能够在羊毛脂的水可提取物成分上生长。
