[Neonatal pulmonary infection due to Chlamydia trachomatis (author's transl)]

A neonate with pneumonia due to Chlamydia trachomatis is reported. The infection was probably generalized because there was hepato-splenomegaly and a granuloma was found on liver biopsy. The frequency of this infection in neonates is probably underestimated in view of the importance of Chlamydia in adult genital disorders. Recent advances in the methods of detection of this organism in cell culture and by serological means should make it easier to diagnose routinely.
