Abstract

Classification of type by means of precipitation after Lancefteld and antibiotic sensitivity test were carried out with 62 strains of streptococcus hemolyticus isolated from scarlet fever patients of the department of infectious diseases and with 42 strains of streptococcus hemolyticus isolated from outpatients of the department of internal medicine.
