Antibiotic exposure delays intestinal colonization by Clostridium difficile in the newborn.

Two antibiotic regimens commonly used in neonatal intensive care were compared for the rate at which Clostridium difficile appeared in the faeces. Over a nine month period neonates with suspected sepsis admitted to a Special Care Baby Unit (SCBU) were randomly allocated to receive either cefotaxime or penicillin and netilmicin. A contemporaneous group also admitted to SCBU but without sepsis served as non-treated controls. Four hundred and sixteen stool specimens from 158 neonates without diarrhoea were analysed every five to seven days until discharge. The results showed that these antibiotics did not encourage gut colonization by C. difficile, that they might even be protective in this respect and that monotherapy with cefotaxime was no more likely to generate C. difficile overgrowth than the penicillin-aminoglycoside regimen.
