Osmosis video - Streptococcus agalactiae (Group B Strep)

Streptococcus agalactiae, also known as group B streptococcus, is a gram-positive, beta-hemolytic, catalase-negative, and bacitracin-resistant bacterium, which can cause several infections in humans. Most frequently, Streptococcus agalactiae causes neonatal infections like pneumonia, sepsis, meningitis, and septic arthritis. It can also cause chorioamnionitis or cystitis in pregnant females. Treatment involves antibiotics like penicillin G or ampicillin, or Cefazolin and Vancomycin. To prevent Streptococcus agalactiae infections in neonates, intrapartum antibiotic prophylaxis can be administered to vaginally colonized pregnant females.
