A comparison of whole cell protein profiles for sporadic human isolates of Streptococcus equisimilis and beta-haemolytic group G streptococci.
Whole cell protein profiles were resolved for Streptococcus equisimilis (group C) and large colony human biotype beta-haemolytic group G streptococci by the use of one dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Strains of S. equisimilis (27 in toto) were distributed among eight patterns designated A to H. Pattern A represented 48.2% of the latter isolates. Strains of group G streptococci (59 in toto) were distributed among sixteen patterns designated 1-16, and there were no predominant patterns which represented more than 20% of all strains. Profiles were reproducible, not susceptible to strain passage, but susceptible to variation in growth media. Considerable homology was observed among bacteria in either Lancefield group.
