OverviewTop of page
Contagious ophthalmia is a disease of sheep and goats characterized by conjunctivitis and keratitis. A variety of organisms have been isolated from the eyes of animals affected with this disease, some of which appear to be primary pathogens and others secondary invaders.
The disease in sheep is widespread in most countries including Africa, Australia, the USA, the UK and Europe. All breeds of sheep are equally affected but the disease in lambs is less severe than in adults, and recently weaned animals are most severely affected. The disease is spread indirectly by flies, long grass and dust contaminated by the tears of infected sheep, or directly by means of exhaled droplets or immediate contact. The prevalence is highest during the warm summer months and when conditions are dry and dusty, and the fly population is heavy.
