<unk> , also known as<unk> <unk><unk>  disease or just<unk> <unk>  strep, is the infection caused<unk> y the<unk> acterium Streptococcus agalactiae (S. agalactiae) (also known as<unk> <unk>  streptococcus or GBS). GBS infection can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems. As other virulent<unk> acteria, GBS harbours an important number of virulence factors, The most important are the capsular polysaccharide (rich in sialic acid), and a pore-forming toxin, β-haemolysin. The GBS capsule is probably the key virulence factor<unk> ecause it helps GBS escape from the host defence mechanisms interfering with phagocytic killing of GBS<unk> y human phagocytes. The GBS β-haemolysin is considered almost identical to the GBS pigment (granadaene). GBS was recognized as a pathogen in cattle<unk> y Edmond Nocard and Mollereau in the late 1880s. It can cause<unk> ovine mastitis (inflammation of the udder) in dairy cows. The species name "agalactiae" meaning "no milk", alludes to this. Its significance as a human pathogen was first described in 1938, when Fry reported three fatal cases of puerperal infections caused<unk> y GBS. In the early 1960s, GBS was recognized as a main cause of infections in newborns. In general, GBS is a harmless commensal<unk> acterium<unk> eing part of the human microbiota colonizing the gastrointestinal and genitourinary tracts of up to 30% of healthy human adults (asymptomatic carriers).
