人工感染柔嫩艾美耳球虫对雏鸡盲肠正常菌群的影响

在对雏鸡人工感染柔嫩艾美耳球虫后6、8、13、20天,分别对感染雏与未感染雏盲肠内容物中梭杆菌、真杆菌、消化球菌、乳酸杆菌、类杆菌、肠球菌、葡萄球菌和肠杆菌等8种主要正常菌群进行定性、定量分析。结果发现在球虫感染第20天,感染组有益菌如乳酸杆菌的数量低于对照组,差异极显著(P<0.01),有害菌如梭杆菌、葡萄球菌数量感染组高于对照组,其中梭杆菌差异显著(P<0.05),葡萄球菌差异极显著(P<0.01)。

Effects of Eimeria tenella Infection on the Normal Flora in the Caecum of Chickling

To find distribution difference of normal flora between Eimeria tenella infected chicklings and control chicklings and offer a theory basis for the treatment of coccidium infection and the development of probiotics,we studied and analysed normal microflora in caecum of coccidium infected chicklings and control chicklings. The normal microflora in caecum of chicklings were analysed by conventional microcological methods. The result showed that at 20 day post infection,the numbers of deleterious mocroflora such as Clostridium(P<0.05)and Staphylococcus(P<0.01) were higher than those of the control,and the number of helpful mocroflora such as Lactobacillus(P<0.01) remained lower than that of the control.
