Abstract

An immunofluorescence method for the identification of groups A, B, C, E, F, and G beta-haemolytic streptococci has been developed, using FITC-labelled F(ab')2 fragments of IgG with optimal staining characteristics. The method is useful for the rapid confirmation of beta-haemolytic streptococci in cultures; in a blind comparison with Lancefield grouping, there was a 97 per cent agreement.
