Lancefield grouping is a serological classification of beta-hemolytic streptococci developed by American microbiologist Rebecca Lancefield in the 1930s. The system groups species by the carbohydrate composition of their cell walls, using designations such as Group A, Group B, Group C, Group D, Group F, and Group G. Group A includes Streptococcus pyogenes, while Group B includes Streptococcus agalactiae. The scheme aided diagnostics and epidemiology for many decades, but modern typing increasingly relies on molecular methods in addition to traditional serology.
