Rebecca Lancefield

Rebecca Lancefield (* 1895, † 1981) shared β - hemolytic streptococci in a so-called Lancefield groups. This Lancefield classification was based on the C- substance, a cell wall polysaccharide constant against which antibodies can be addressed. The group D is the antigen, in contrast to the other Lancefield groups are not a polysaccharide but a cell wall-bound teichoic acid. The classification made ​​Lancefield using the latex agglutination. Medically significant are the groups A (Streptococcus pyogenes ), B (Streptococcus agalactiae ) and group D Enterococcus faecalis and Enterococcus faecium. The term Streptococcus faecalis used in older books no longer corresponds to the current nomenclature is therefore no longer correct. Also streptococci group F may be medically relevant, eg in wound infections. Streptococcus anginosus, in low numbers belong to the normal throat flora, but it can also be the cause of Tonsillarabszesse.
