Group B Streptococcal (GBS) infections pose a great threat to mortality in neonates. Neonates are often exposed to GBS both before, during, and after delivery, which can cause a range of health problems including meningitis, sepsis, or stillbirth. One of the major virulence factors that contributes to the infectivity of the pathogen is the bacterial capsule. The capsule is a polysaccharide matrix surrounding the cell which helps in the evasion of host defenses, and penetration into normally sterile sites like the bloodstream. The highly conserved GBS protein CpsA has been shown to regulate expression of the capsule. The objective of …

Streptococcus agalactiae, otherwise known as Group B Streptococcus (GBS), is a zoonotic, Gram-positive, commensal and invasive bacteria which is the leading cause of neonatal bacterial infections. These bacterial infections include sepsis, meningitis, pneumonia, and bacteremia. In neonates, GBS is most commonly transferred to the child in utero or during birth when the child aspirates amniotic or vaginal fluids. GBS can also infect the child through the bloodstream while in utero, causing premature births or still births. Children who survive the initial infection develop severe morbidities which include mental retardation, cerebral palsy, and seizures. GBS can also affect immunocompromised adults, …
