The left eyes of 10 conventional dairy cross calves were inoculated with a pathogenic strain of Moraxella bovis and lesions of infectious bovine keratoconjunctivitis developed in nine of these eyes. M bovis was isolated from all inoculated eyes and lesions developed in five out of 10 eyes which had become naturally infected. The clinical and microbiological findings were similar to those described in field cases.
