Abstract
By the use of PYC enrichment medium, the recovery of fecal streptococci from river water has been increased more than twofold over that of M-Enterococcus Agar. Of the isolates tested, 94.6% could be classified as enterococci or enterococcus biotypes. This method seems to yield a larger number of strains which would not normally be revealed. Serological typing of atypical streptococcus strains isolated indicates that the majority of these “biotypes” can be placed in the enterococcus group.
