Concurrent conjunctivitis and placentitis in aborted bovine fetuses.
Consistent histopathological lesions were found in 10 out of 136 aborted fetuses examined during a three year period, using a multi-disciplinary diagnostic investigation technique. Fetuses exhibited a generalized mononuclear inflammatory cell infiltration, accompanied by distinctive lesions of conjunctival hyperplasia and goblet cell formation, alveolitis, and necrotic placentitis. In two cases where amnion was also examined, a chronic amnionitis was present. No consistent laboratory findings could be related to these cases. The fetal and placental lesions described were similar to those associated with experimental inoculation of Ureaplasma diversum in pregnant cows, and with field isolations of the same organism in aborting cattle.
