Group B Streptococcal Infection Pathophysiology
In 1933, a researcher by the name of Lancefield subdivided the beta-hemolytic streptococci into specific groups. The groups were designated as A, B, C, D and E. Only groups A, B, C, and D are commonly involved in human disease. Group B streptococci (GBS) are also classified into subtypes on the basis of cell wall antigens.
This form of strep bacteria produces toxins that can affect red blood cells and other body tissues. It causes infections ranging from very mild to deadly.
