Group B Streptococcus (GBS), also known as Streptococcus agalactiae, is a type of bacteriathat can cause serious illness and sometimes death, especially in newborn infants and the elderly. It is also an important pathogenin veterinary medicine, as it causes bovine mastitis(inflammationof the udder) in dairy cows. The name alludes to this ("agalactiae"=no milk).

Streptococcusis a genusof spherical, Gram-positivebacteria of the phylumFirmicutes. Streptococcus agalactiaeis a gram-positivestreptococcus characterized by the presence of Group B Lancefield antigen, and so takes the name Group B Streptococcus. GBS is a member of the normal flora of the gutand female urogenitaltract, so many women are carriersof this bateria without knowing it. GBS colonizationcan be chronicor intermittent.

Perinatal disease

GBS bacteria can be passed from a pregnantwomen to her baby during labor, if she is a carrierof the bacteria.

Perinatal Group B Streptococcal Disease

Approximately 10% to 30% of pregnant women are colonized with GBS in the vagina or rectum. Since the bacteria can come and go, testing for GBS is needed every pregnancy. Toward the end of a pregnancy, the vaginaand rectumare cultured with a swab at a prenatalappointment. Women with GBS are given an antibioticduring labor. Evidencebased researchstudies show that using this test can reduce infant infections.

Perinatal GBS disease prevention

Collaborative efforts of clinicians, researchers, professional organizations, parent advocacy groups, and the public healthcommunity developed recommendations for intrapartum prophylaxisto prevent Perinatal GBS disease. Many organizations have developed Perinatal GBS diseasepreventionand education programs to reduce the incidenceof the disease. Information about the recommendations and the prevention programs can be found in medical journalsand on the internet.
