The phylogenetic diversity of the fecal bacterial community in Holstein cattle was determined by 16S ribosomal RNA gene sequence analysis. The sequences were affiliated with the following phyla: Firmicutes (81.3%), Bacteroidetes (14.4%), Actinobacteria (2.5%), and Proteobacteria (1.4%). The Clostridium leptum subgroup was the most phylogenetically diverse group in cattle feces. In addition, a number of previously uncharacterized and unidentified bacteria were recognized in clone libraries.
