摘要
应用２０日龄白来航小母鸡的肠道内容物，研究消化道部分区段微生物区系，分离鉴定出需氧菌和厌氧菌，并进行了毒力试验。结果表明，每克肠内容物含细菌的对数值（ｌｏｇｎ／ｇ）为：空肠中消化球菌９．６±０．２、双歧杆菌９．４±０．５、拟杆菌１０．６±０．６、葡萄球菌６．６±０．６、乳杆菌９．３、肠杆菌６．８±０．４；盲肠中葡萄球菌６．７±０．６、消化球菌９．８±０．３、双歧杆菌９．２±０．８、拟杆菌１０．２±０．２、棒状杆菌８．７±０．４、肠杆菌６．８±０．３、链球菌７．２±０．２、乳杆菌９．６±０．４、酵母菌４．２±１．４．
The microfloras in some sections of digestive tract were studied with the intestine contents of the 20dayold white leghorn hens.The aerobesstaphylococci,E.coli.,Corynebecterium,Yeast and the anaerobesmycobacterium,Lactic acidbacterium Didestire coocus,Bacteroides,Fusiformis fragilis,S.Lactis were isolated and identified.The toxicities of the above bacteria were tested and the logarithmic values of the bacteria per gram content (Long n/g) of the intestines of the hens were determined.The results were didestire coccus 9.6±0.2,mycobacterium 9.4±0.5,bacteroides 10.6±0.6,staphylococci 6.6±0.6,Lactic acid bacterium 9.3,E.coli 6.8±0.4 in the jejunum and staphylococci 6.7±0.6,Digestive coccus 9.8±0.3,mycobacterium 9.2±0.8,bacteroides 10.2±0.2,corynebacterium 8.7±0.4,E.coli.6.8±0.3,S.Lactis 7.2±0.2,Lactic acid bacterium 9.6±0.4,yeast 4.2±1.4 in the caecum,respectively.
