<prompt> A child presents with sepsis. Bacteria isolated showed beta hemolysis on blood agar, resistance to bacitracin, and a positive CAMP test. The most probable organism causing infection is:S. PyogenesS. AgalacitaeEnterococcusS. Pneumoniae  <response>: Streptococcus agalactiae is a group B hemolytic streptococci. They are normal flora of the female genital tract and an impoant cause of neonatal sepsis and meningitis. They hydolyze sodium hippucrate, typically beta hemolytic, gives a positive response to cAMP Christie, Atkins and Munch-Peterson and resistant to bacitracin. Ref: Medical Microbiology By William L.
