چکیده
The isolation of two coagulase-negative strains of Staphylococcus pyogenes is reported, and their biochemical characteristics are given. The reliability of coagulase tests alone in the identification of Staph. pyogenes is discussed, and the deoxyribonuclease test is recommended as a useful confirmatory test.
