molecular diversity of bacteria in yunnan yellow cattle (bos taurs) from nujiang region, china.the rumen content of four yunnan yellow cattle (bos taurs) were collected to determine the bacteria diversity by using 16s rrna gene sequence analysis. a total of 129 sequences were examined and the sequences were referred as 107 otu (operational taxonomy unit) according to the similarity level of 97% in gene sequence. similarity analysis revealed that yunnan yellow cattle had 12 sequences (10 otu) shared 97% or greater similarity with cultured rumen bacteria butyrivibrio fibrisolvens, succinicl ...201121598111
dominant bacterial communities in the rumen of gayals (bos frontalis), yaks (bos grunniens) and yunnan yellow cattle (bos taurs) revealed by denaturing gradient gel electrophoresis.the dominant rumen bacteria in gayals, yaks and yunnan yellow cattle were investigated using pcr-dgge approach. the analysis of dgge profiles, identification of dominant bands and phylogenetic analysis 16s rdna sequences in dgge profiles were combined to reveal the dominant bacterial communities and compared the differences between those cattle species. dgge profiles revealed that gayals had the most abundant dominant bacteria and the lowest similarity of intraspecies between individuals than ot ...201021140219
