What is Which among the following is the most common cause of early-onset sepsis in neonates? and explain in detail?
Early-onset infection (< 3 days) is most often caused by group B beta-hemolytic streptococci (GBS) and gram-negative enteric pathogens (most commonly E coli). Other organisms to consider are non-typeable Haemophilus influenzae, Enterococcus, Staphylococcus aureus, other streptococci and Listeria monocytogenes. Late-onset sepsis (> 3 days of age) is caused by coagulase-negative staphylococci (most common in infants with indwelling central venous lines), S aureus, GBS, Enterococcus, and gram-negative organisms, in addition to Candida species.
