| Abstract |
|
The present study was undertaken to obtain the basic knowledge on the distribution of intestinal microflora and characterization of Bifidobacterium isolated from the intestine of cattle, pigs, chicken and dogs. Bacteroidaceae and Streptococcus were isolated from the feces of cattle as predominant organisms, and Bifidobacterium was in counts of $8.65{pm}0.21$ log 10 organisms. Bacteroidaceae, Eubacterium and Peptococcaceae counts on the feces of pigs were particularly high, but Bifidobacterium did not isolated. In hens and dogs, the counts of Bifidobacterium were $7.60{pm}0.71$ and $8.15{pm}2.04$ log 10 organism, respectively. Isolated 7 Bifidobacterial strains were identified respectively to B. thermophilum from cattle, B. pullorum and B. animalis from pigs, and B. longum, B. adolescentis and B. pseudolongum from dogs by their carbohydrate fermentation ability. |
