The thoracic air sacs of poults at one day of age were examined to compare those of normal, saleable poults with those of sibs culled(1) at hatching at three stages in the laying season. Lesions of airsacculitis were recorded and the air sacs were cultured for mycoplasma. Impression smears of the thoracic air sacs were stained with rabbit anti-Mycoplasma meleagridis serum conjugated with fluorescein isothiocyanate and examined to determine the location and infection rate of the organism. M. meleagridis were observed closely associated with or within epithelial cells of the air sac; within mononuclear cells and as extracellular "microcolonies". The lesion and infection rate of cull poults in most hatches exceeded that of normal poults and infection with M. meleagridis was more often expressed (as a lesion) in cull than in normal poults.
对一日龄雏鸡的胸气囊进行检查，以比较正常、可销售雏鸡与在产蛋季节三个阶段孵化时被淘汰的同胞雏鸡的胸气囊。记录气囊炎病变情况，并对气囊进行支原体培养。用异硫氰酸荧光素偶联的兔抗鸡败血支原体血清对胸气囊印片进行染色，检查以确定该病原体的位置和感染率。观察到鸡败血支原体与气囊上皮细胞紧密相关或在其内部；在单核细胞内以及作为细胞外“微菌落”存在。大多数批次中被淘汰雏鸡的病变和感染率超过正常雏鸡，并且鸡败血支原体感染（以病变形式）在被淘汰雏鸡中比在正常雏鸡中更常出现。
