Growth Requirements of Streptococcus mitis and Sulfonamide Resistance.

Experimental Biology and Medicine, 1950
Summary1. Differences in the vitamin requirements of susceptible strains of S. mitis, their artificially-induced resistant variants and a naturally-resistant S. fecalis, have been determined. 2. The greatest difference was in the PGA requirements, the mitis strains grew in its absence; the resistant mutants required PGA. 3.
