Penicillin tolerance among 67 strains of beta-hemolytic streptococci was examined by determining the ratio of the minimal bactericidal concentration to the minimal inhibitory concentration as 32 or greater. Tolerance was demonstrated in 15 group A st

A sensitive dye-binding assay was employed to study the extracellular hyaluronidase produced by three penicillin-sensitive strains of group A streptococci belonging to M types 4, 24 and 28. Enzyme was produced by all strains at appreciable levels. Su

Production of hyaluronidase by 147 strains of beta hemolytic streptococci was studied employing a sensitive dye-binding assay and levels of enzyme activity were evaluated statistically. The analysis of variance showed that group A strains isolated in
