==Overview==
==[[Group B streptococcal infection historical perspective|Historical Perspective]]==
Infection with '''Group B Streptococcus''' (GBS), also known as '''[[Streptococcus agalactiae]]''', can cause serious illness and sometimes [[death]], especially in newborn infants and the elderly. Group B streptococci are also important [[pathogen]]s in veterinary [[medicine]], because they can cause bovine [[mastitis]] ([[inflammation]] of the [[udder]]) in dairy cows. The species name "agalactiae" meaning "no milk", alludes to this.
[[Streptococcus]] is a [[genus]] of spherical, [[Gram-positive]] bacteria of the phylum [[Firmicutes]]. [[Streptococcus agalactiae]] is a [[gram-positive]] streptococcus characterized by the presence of Group B [[Lancefield antigen]], and so takes the name Group B Streptococcus.

[[Image:Group B Strep.jpg|left|500px|U.S. Prevention of Perinatal Group B Streptococcal Disease, CDC]]  
GBS is a member of the normal [[gut flora|flora of the gut]] and female [[urogenital]] tract, so many women are [[asymptomatic carrier|carrier]]s of this bacterium without knowing it. GBS colonization can be [[chronic (medicine)|chronic]] or intermittent.


GBS bacteria can be passed from a [[pregnant]] women to her baby during [[childbirth|labor]], if she is a [[asymptomatic carrier|carrier]] of the bacteria.

One out of every four women are colonized with GBS in the vagina or rectum.<ref name="cdcwebsite">

Toward the end of a pregnancy, the [[vagina]] and [[rectum]] are cultured with a swab at a [[prenatal]] appointment. Women with GBS are given an [[antibiotic]] during labor. Evidence based research studies show that using this test can reduce infant [[infection]]s.


===Perinatal GBS disease prevention===
==[[Group B streptococcal infection differential diagnosis|Differentiating Group B Streptococcal Infection from other Diseases]]==
Through collaborative efforts clinicians, researchers, professional organizations, parent advocacy groups, and the [[public health]] community developed recommendations for intrapartum [[prophylaxis]] to prevent Perinatal GBS disease. Many organizations have developed [[Perinatal Group B Streptococcal Disease|Perinatal GBS disease]] [[prevention]] and education programs to reduce the [[incidence]] of the disease. Information about the recommendations and the prevention programs can be found in [[medical journal]]s and on the internet.
