Abstract
Environmental factors that contribute to the pathogenesis of infectious bovine keratoconjunctivitis (IBK) include face flies, ultraviolet (UV) radiation, and mechanical irritation from plant awns or dust. Limited research has shown face fly control to be associated with lower incidence of IBK. UV radiation is known to cause corneal irritation and damage in mammalian species. The increased formation of corneal dark cells has been observed following UV radiation in exposed calves. Moraxella bovis preferentially binds to corneal dark cells where it can be found in pits, which may be formed due to bacterial contact. Little is known about the efficacy of management of pasture plants on the prevention of IBK.
