Identification of bacterial populations in dairy wastewaters by use of 16S rRNA gene sequences and other genetic markers.

abstract：:The erythromycin resistance gene ermB has been found in a variety of gram-positive bacteria. This gene has also been found in Bacteroides species but only in six recently isolated strains; thus, the gene seems to have entered this genus only recently. One of the six Bacteroides ermB-containing isolates, WH207, could t...
