Impact of Intrapartum Azithromycin on the Carriage and Antibiotic Resistance of <i>Escherichia coli</i> and <i>Klebsiella pneumoniae</i> in Mothers and Their Newborns: A Substudy of a Randomized, Double-Blind Trial Conducted in The Gambia and Burkina Faso

Intrapartum azithromycin decreased E. coli carriage but increased both K. pneumoniae carriage and azithromycin resistance in both bacteria. These data need to be considered together with efficacy results to balance the potential short- and long-term impact of the intervention.
