Pinkeye in Cattle
Pinkeye in Cattle
Infectious bovine keratoconjunctivitis (IBK), commonly referred to as “pinkeye,” is a costly and highly contagious ocular disease of cattle. It arises from an initial insult to the cornea and subsequent invasion by bacterial pathogens, most notably Moraxella bovis, although other pathogens can play a role. Clinical signs can quickly progress from watery, red, painful, light-sensitive eyes to significant corneal ulcerations and blindness if left untreated. Pinkeye is multifactorial in nature and derives influence from the environment, pathogens, and host animal.


Economic Impact
It has been estimated that pinkeye affects over 10 million calves annually in the United States.1 Economic losses arise from reduced wean weights, slaughter weights, and treatment costs, which can easily exceed $100 per head.1
