Isolation and Identification of normal flora in healthy Nipponia Nippon enteron;

Comparison of the quantity of normal flora in digestive tracks betweeol SPF and ordinary chicken;

Objective To test the amount of normal flora from gastrointestinal contents and fresh dejection of adult Guizhou miniature pig,and to offer reference value for related animal experiment.

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.

It was carried out with the culture solution of Lactobacillus fed to the day-old chickens to observe the effects on the colonization of the main normal microflora in chickens cecums.

The experiment was conducted to study the normal microflora in largeand small intestines of Belgium rabbits during three different stages,namely,the new-born,sucking and weanling periods.

The results are treated in Statistics and the eight kinds of main normal microbial flora logarithmic average value are obtained.

The study was carried out with the method of diluting and dripping to make qualitative and quantitative detection on 10 kinds of normal microbial flora from 30 cattle mammary gland.

The study was carried out with the method of diluting and dripping to make qualitative and quantitative analysis on 10 main kinds of normal microbial flora(Corynebacterium,Lactobacillus, Staphylococcus,Bacillus,Bifidobacterium,Escherichia,Enterococci,Eaceroides,Eubacterium and Clostridium)from four parts of cattle mammary gland.
