A newborn of 7 days old presented with meningitis. Most common cause is ____________

Most common cause meningitis in newborn is due to EColi. The incidence of early-onset meningitis has been greatly reduced by the initiation of intrapaum antibiotics to combat Group B streptococcus (GBS) infection. However, GBS remains the most common cause of both meningitis and neonatal sepsis, causing greater than 40% of all early-onset infections.The next common pathogen in this group is E. coli and has emerged as the most common cause of early-onset sepsis and meningitis among very low bih weight (VLBW, less than 1500 g) infants.
