Evaluation of 8 physiological characteristics of clinically isolated Staphylococci and Micrococci

307 cultures of staphylococci and micrococci were isolated from clinical sources and were subjected to 8 different physiological tests for the recognition of pathogentic strains. These tests were as follows; catalase, oxidase, fermentation and oxidation of glucose and mannitol, v.p. and coagulase activity, heat resistance endonuclease, and lipase production. From the results obtained it can be concluded that for the recognition of pathogenicity of staphylococci, coagulase, heat resistance endonuclease and fermentation of mannitol should be carried out.
