Abstract
Haemolytic streptococci have been obtained from throat cultures of 92 per cent. of cases of scarlet fever in the first two days of the disease.Strains from 210 cases were found to belong to two main serological types, Type I strains being obtained from 119 cases, and Type II strains from 57 cases.Strains obtained from cases occurring in members of the same family were found to be mainly of the same serological type.Strains obtained from cases in small isolated outbreaks were found to be of the same serological type.Note. These Type I and Type II strains have been examined by Dr Griffith, Ministry of Health, Pathological Laboratory, London, and have been found to conform to his main types.
