May Trichomonas vaginalis provoke conjunctivitis?

In the world literature we have found descriptions of five cases of Trichomonas vaginalis in the conjunctiva. Conjunctival swabs taken from 122 patients with conjunctivitis or keratitis revealed no flagellate micro-organisms on phase-contrast microscopy and culture. Neither did conjunctival swabs from 272 newborn infants, in spite of the fact that 3.7 per cent of their mothers had Trichomonas in the vagina. Trichomonas vaginalis is hardly likely to be responsible for conjunctivitis.
