Differential recovery of Streptococcus mutans from various mitis-salivarius agar preparations

Abstract
Recoveries of S. mutans from human dental plaque were lower when plated on mitis-salivarius agar obtained from Baltimore Biological Laboratories than on mitis-salivarius agar obtained from Difco Laboratories. No difference in recoveries of established laboratory strains of S. mutans was observed between these 2 agar preparations.
