title: Mycoplasmas associated with bovine conjunctivitis and keratoconjunctivitis.
abstract: In two separate herds of fattening calves a sudden-onset outbreak of ocular disease with profuse lacrimation occurred. The disease resembled the early stage of infectious bovine keratoconjunctivitis but after a few days the clinical signs of bronchopneumonia appeared. From conjunctival swabs Mycoplasma (M.) bovigenitalium, M. bovirhinis and infectious bovine rhinotracheitis (IBR) virus were isolated. Moraxella bovis infection was not established. In one of the herds M. bovigenitalium was also found in the pneumonic lungs of dead calves. In one herd M. bovoculi was isolated from a cow with chronic keratoconjunctivitis, housed together with affected calves. Mycoplasmas were not isolated from ocular swabs of six bulls originating from a Reproductive Centre with temporary occurrence of unilateral serous conjunctivitis resistant to antibiotic therapy.
