title: Fetal and placental lesions in bovine abortion due to Tritrichomonas foetus.
abstract: Laboratory records and histologic material from 13 cases of naturally occurring, early- to late-term bovine abortion due to Tritrichomonas foetus were examined. Placentitis was present in all placentas. Pyogranulomatous bronchopneumonia was in six of the 11 lungs which were examined. Trichomonad organisms were demonstrated within the placental stroma in all cases and free or phagocytized in pulmonary airways in seven cases.
