Urinary tract infection with Trichomonas vaginalis in a premature newborn infant and the development of chronic lung disease.

We report a case of a low-birth-weight infant with an infection of the urinary tract with Trichomonas vaginalis, who later developed cystic chronic lung disease suggestive of Wilson-Mikity syndrome. Although she had mild respiratory distress syndrome at birth, the extent of the chronic lung disease was out of proportion to the initial illness. We speculate that maternal infection with this organism may have resulted in an inflammatory response that led to its development.
