| 摘 要： | 利用扫描电镜观察健康鸡与患球虫病鸡消化道（嗉囊、回肠和盲肠部位）中正常菌群黏附状况发生的变化。结果表明，健康鸡消化道黏膜表面均匀覆盖着大量的正常菌群，黏膜完整，其中嗉囊表面黏附的乳酸杆菌最为致密；而患球虫病鸡消化道黏膜脱落，正常菌群明显减少，这是病鸡发生腹泻的主要原因。

| Abstract: | A scanning electron-microscopic observation on the normal microflora in the digestive tract(craw,ileum and caecum) of healthy and diseased chickens showed that in the digestive tract of healthy chicken,mucosa was integral,its surface was evenly covered with a lot of normal microflora,and the lactobacillus adhered on the surface of craw had the greatest density.In the digestive tract of chicken suffered from coccidiosis,the mucosa was shed,and the individuals of normal microflora decreased markedly,which could be the main reason of diarrhoea. |

| Keywords: | normal microflora mucosa of digestive tract chicken ultra ultramicroscopic observation |
