Chlamydia trachomatis‐associated respiratory disease in the very early neonatal period

Of 103 preterm neonates admitted consecutively to the neonatal intensive care unit soon after birth for respiratory distress, 8 were found to be Chlamydia trachomatis-positive as early as within the first 24 h of life. All these patients required mechanical ventilation and supplemental oxygen. Six infants had evidence on chest radiographs of hyaline membrane disease, one of pneumonia, and one of slight bilateral parenchymal changes. Our results suggest that the presence of C. trachomatis in preterm infants with neonatal respiratory distress is probably not an infrequent event.
