Clinical examination of 2.540 cattle in six herds in Kenya revealed a high incidence of infectious bovine keratoconjunctivitis. The disease with varying degrees of ocular involvement was observed in 328 (12.9%) of the animal’s examined. 184 (56. 1%) of the affected animals showed bilateral eye Involvement while only one eye was affected in the remaining 144 cattle. Bacteriological and virological examination or ocular secretions collected from 25 eyes of cattle with the disease resulted in the isolation of Neisseria catarrhal is from all the affected eyes. The effectiveness of penicillin and chloramphenicol ophthalmic ointments in the treatment of the disease was examined. No Significant differences were observed in the recovery rates between the animal treated either with penicillin or chloramphenicol ointments. Recovery rates were higher in the animals treated daily for 7 days than in those animals subjected to three treatments given at 2-day intervals.
