The mother has had no prenatal care. The newborns temperature is 39.7C 103.5F. Physical examination shows scleral icterus. Her leukocyte count is 36,000mm3 85 segmented neutrophils. An organism is isolated from the blood. When grown together on sheep agar, the isolated organism enlarges the area of clear hemolysis formed by Staphylococcus aureus. Which of the following is the most likely causal organism?? A: Pseudomonas aeruginosa, B: Listeria monocytogenes, C: Streptococcus pyogenes, D: Streptocccus pneumoniae, E: Streptococcus agalactiae,  <response>: This is a medical question asking about the most likely causal organism in a newborn with symptoms of lethargy, high fever, scleral icterus, high leukocyte count with neutrophilia, and positive blood culture that enhances hemolysis of Staphylococcus aureus. The key findings pointing towards the diagnosis are: - Newborn infant - Lethargy and high fever - Scleral icterus indicating hyperbilirubinemia- High leukocyte count with neutrophilia indicating bacterial infection- Positive blood culture with organism that enhances hemolysis of Staph aureus, indicating beta-hemolytic streptococcusBased on these key findings, the most likely organism is Streptococcus agalactiae, also known as Group B Streptococcus GBS. GBS is a common cause of neonatal sepsis and meningitis. It is beta-hemolytic, enhancing hemolysis of Staph aureus on blood agar. Other options like Pseudomonas, Listeria, Strep pneumoniae are less likely in a newborn. Strep pyogenes is beta-hemolytic but less common than GBS in newborns.E: Streptococcus agalactiae
