Central Veterinary Institute, Lelystad, The Netherlands.

Five sheep, free from Mycoplasma conjunctivae and ocular Chlamydia infection, were experimentally inoculated with M. conjunctivae and five more sheep were exposed to the infection by contact. Keratoconjunctivitis developed in all ten sheep. As in natural outbreaks of infectious keratoconjunctivitis (IKC), clinical signs were generally moderate and transient, and recurred in some sheep. M. conjunctivae was detected throughout the 53-day observation period. Clinical diagnosis was confirmed by histopathologic examination of three sheep. Moraxella ovis, found in six of the ten sheep before the start of the experiment, appeared to play no etiologic role in the development of IKC.
