Step-by-step explanation:
Infectious Bovine Keratoconjunctivitis Causative Agent
The causative agent of infectious bovine keratoconjunctivitis, also known as pinkeye in cattle, is Moraxella bovis. This bacterial pathogen can lead to inflammation and infection of the cornea and conjunctiva in cattle, resulting in discomfort and potential vision impairment. Good husbandry practices, including minimizing irritants like dust and flies, and vaccinations can help prevent the spread of this disease. It's important to treat affected animals promptly to reduce the potential for serious eye damage or blindness.
