Abstract
A new medium designated as D streptococcus-enterococcus broth was formulated and evaluated for the enrichment and isolation of strains of serological group D streptococci. This medium was made by modifying Todd-Hewitt broth. Most-probable-number multiple-tube and membrane filter techniques were employed to estimate the numbers of enterococci in known cultures, wastewater, and other samples. Preliminary most-probable-number counts with this medium were as much as 3 logs higher than those counts obtained from four other media with which it was compared. The methodology for using this medium to estimate the numbers of group D streptococci in water is discussed.
