“…`Although Fry and Eng (2) were the first to describe three fatal group B postpartum infections and to point out the clinical importance of GBS in human infections, it was not until 1973 that GBS were firmly established as a major cause in perinatal infections (3)(4)(5)(6)(7)(8). Meanwhile a wealth of information has been accumulated and has been summarized in a number of review articles (9-11) .GBS have been isolated with increasing frequency from infants with early-and late-onset septicemia and meningitis (5, 12), but they also contributed to more infrequent infections in adults such as abortion, abscesses, bacteremia, impetigo, arthritis, septicemia, and urinary tract infections (2,5,8,(13)(14)(15)(16)(17)(18)(19)(20) .Besides the common group antigen, most strains of GBS share an extracellular protein first described in 1944 by Christie, Atkins, and Munch-Petersen, which accordingly was named CAMP factor (21). The CAMP factor causes lysis of red blood cells that contain at least 45 mol -% of sphingomyelin (22) and which have been exposed to Staphylococcus aureus #-toxin (sphingomyelinase) .…”
