Los autores evaluaron el impacto de la exposición intraparto a anfibióticos respecto a graves infecciones bacterianas de comienzo tardío (de 7 a 90 días después de nacer) entre 90 niños infectados, en comparación de otros 92 sin tal infección.
Un 41% de los niños infectados habían sido expuestos a antibióticos durante el parto, por sólo el 27% del grupo control. Los niños infectados tuvieron cinco veces más de probabilidades de estar expuesto a antibióticos de amplio espectro que los del grupo control.
El 41% de las bacterias aisladas en los niños infectados eran resistentes a la ampicilina y el 65% de las aisladas en niños infectados, expuestos a antibióticos durante el parto eran también resistentes a la ampicilina.
La relación entre organismos resistentes a la ampicilina y exposición intraparto a antibióticos fue significativa para infecciones del tracto urinario y otras más graves, como meningitis u onfalitis.
