[Data on the identification of staphylococci of hospital origin. Report 2. Method of biological typing of S. epidermis].
In accordance with the principles of numerical taxonomy the authors elaborated a new method of biological typing of S. epidermidis strains of hospital origin based on the use of 5 tests (gelatinase, hemolysis, lecithinase, phosphatase, lysozyme). The suggested scheme includes 5 biotypes. In typing 690 S. epidermidis strains it was revealed that 47.5% belonged to biotype 1,14.4% - to type 2,11.2% - to type 3,7.7% - to type 4,14.5% - to type 5, and 4.7% were nontyping strains. The suggested scheme permitted better differentiation of the cultures under study than methods of biological typing suggested earlier by foreign authors. The new scheme requires wide approbation.
