First Report of Moraxella Bovis Infection in Indian Cattle

摘要

Infectious bovine keratoconjunctivitis (IBK) is a highly contagious, painful ocular disease that affects cattle of all ages and that occurs worldwide. This article focuses on the first report of a dairy herd IBK outbreak at Bareilly, Uttar Pradesh–State, India, during rainy season. The organism was isolated from seven crossbred male (HFx) calf of 6–7 month old from ocular discharge. Organism was identified on the basis of colonial morphology and biochemical characteristics. Examination revealed mild to severe swelling surrounding affected eyes, and profuse lacrimation. Lesions typically affected both the eyes, and involved the eyelid skin, conjunctiva and corneal opacity. Effective treatment of IBK is very important, as in untreated cases the corneal opacity may lead to corneal ulceration and blindness inturn it finally leads to production loss of animals. Drugs may be delivered to the eye in several ways: subconjunctival injection, topical application and systemic administration. Topical instillation of silver nitrate (1%) and zinc sulphate (0.4%) eye drops along with OTC parenterally, twice daily for 7–15 days to all the infected animals, which also exhibited corneal opacity were found to be more effective and led to cure within fortnight.
