The patients mother says symptoms acutely onset 12 hours ago and have not improved. No significant past medical history. His mother did not receive any prenatal care, and she had rupture of membranes 20 hours prior to delivery. His vital signs include: heart rate 150min, respiratory rate 65min, temperature 39.0C 102.2F, and blood pressure 6040 mm Hg. On physical examination, the patient has delayed capillary refill. Laboratory studies show a pleocytosis and a low glucose level in the patients cerebrospinal fluid. Which of the following is the most likely causative organism for this patients condition?? A: Cryptococcus neoformans, B: Enterovirus, C: Group A Streptococcus, D: Group B Streptococcus, E: Streptococcus pneumoniae,  <response>: This is a question about identifying the most likely causative organism in a newborn with signs and symptoms of sepsis including fever, irritability, lethargy, poor feeding, tachycardia, tachypnea, and hypotension. The key clues are that the newborn is less than 24 hours old, born at home after rupture of membranes for 20 hours prior to delivery, and has an abnormal CSF profile showing pleocytosis and hypoglycorrhachia. The organism choices provided include bacteria like Group A and Group B streptococcus and S. pneumoniae as well as fungi like Cryptococcus and viruses like enterovirus. Given the clinical scenario of early onset sepsis in a newborn, the most likely organism is Group B streptococcus. Prolonged rupture of membranes increases the risk of ascending infection and early onset GBS sepsis. The other organisms are less likely in this specific clinical scenario.D: Group B Streptococcus
