Moraxella bovis, a gram-negative coccobacillus, is the most common cause of infectious bovine keratoconjunctivitis (IBK) in cattle. This organism is not a cause of keratoconjunctivitis in sheep and goats. The disease includes conjunctivitis and ulcerative keratitis.


Can humans get Moraxella bovis?

Moraxella bovis is normally transmitted to humans via infected milk as well as via aerosols but in develop countries used pasteurization which kills most of the bacteria in milk and infected cattle immediately culled.

How does Moraxella bovis spread?

M. bovis can be transmitted by direct contact or by aerosol of nasal or ocular discharges, though the most common mechanism of transmission is via fly vectors. The flies act both as a carrier and as an ocular irritant that allows establishment of the infection.

Where is Moraxella bovis found?

Moraxella bovis is usually found in discharge from the affected eye; other bacteria, such as Staphylococcus and Corynebacterium, are also often present. Ultraviolet rays from the sun may play a role in the inflammation; face flies may transmit the disease.

How do you treat IBK?

Another common treatment for IBK is bulbar conjunctival injection with penicillin, but lack of a label indication for IBK/Moraxella may make other approved treatments more attractive. For infectious keratitis in sheep and goats, topical oxytetracycline and antiseptic sprays are currently approved treatments.

Treatment. There is no specific treatment for IBR, secondary bacterial infections can be managed with antibiotics and animals with a high fever treated with non steroidal anti-inflammatories. Preventative vaccination of the remaining herd members may aid in minimising disease spread.

Can goats get pink eye?

Pinkeye is a highly contagious infection that spreads through contact. Outbreaks frequently occur when new goats are introduced to the herd, when they are transported or relocated, and when goats experience severe stress due to very dry or cold weather.

How Mycobacterium bovis affects animals?

Bovine Tuberculosis (TB) is an infectious disease of cattle. It is caused by the bacterium Mycobacterium bovis (M. bovis) which can also infect and cause disease in many other mammals including humans, deer, goats, pigs, cats, dogs and badgers. In cattle, it is mainly a respiratory disease but clinical signs are rare.

What is silage eye?

Pink Eye is also called Infectious Bovine Keratorconjunctivits (IBK), Silage eye, or conjunctivitis and is one of the most common diseases of cattle. The disease has a world-wide distribution and is usually seen in epidemics when a chronically or subclinically infected animal enters a herd.

What beef breed cattle is also considered a milking breed?

Holsteins are best known as dairy cows, but those animals not used for breeding stock or milk production are raised for their value as beef cattle. Holsteins originated in Holland more than 2,000 years ago, and were brought to America in the 1850s as demand for milk grew in this country.

What happens when cows get pink eye?

Pinkeye results in mild to severe disease, blindness if left untreated and can cause significant reductions in performance and cattle value. The primary infectious agent for pinkeye is the bacterium Moraxella bovis. This bacterium is found in the eyes of many recovered and apparently normal cattle.

What is the shape of Moraxella bovis?

Moraxella bovis is a gram-negative coccobacillus, non-motile, free-living bacteria measuring between 0.6 – 1.0 µm in diameter (2,4,8), lacking flagella with varying amounts of pili.

Is Mycobacterium bovis Gram positive or negative?

Mycobacterium bovis (M. bovis) is part of the of mycobacterium tuberculosis complex. It is an acid fast, gram positive bacilli, that is non-spore forming, non-motile, slightly curved, aerobic and slow-growing.

What is Kerato conjunctivitis?

Keratoconjunctivitis refers to an inflammatory process that involves both the conjunctiva and the superficial cornea. It can occur in association with viral, bacterial, autoimmune, toxic, and allergic etiologies. This activity outlines the presentation, evaluation, and treatment of keratoconjunctivitis.

How long does pink eye last in cattle?

Recovery is usually complete 3–5 weeks after the initial infection. Most affected eyes heal completely; in some, scarring results in a small bluish-white spot remaining in the centre of the cornea. In about 2% of cases, the affected eye remains blue and the animal remains blind in that eye.

Why is my goats eye white?

The bacteria implicated (Chlamydophila, Mycoplasma or Moroxella) cause the condition to be highly infectious and easily transmitted between infected goats. The cornea (surface of the eyeball) may at first appear grey and turn blue/white. The eyelids may stick together and excess tear production occurs.

What causes eye problems in goats?

Goats can become affected with eye problems that come from infectious or environmental irritants. Two infectious irritants include chlamydia and mycoplasma. With chlamydia, infection can spread very rapidly throughout the herd, eventually affecting up to 90% of the animals in the herd.

Why are my goats eyes watering?

Common causes of eye discharges in export livestock are ocular irritants, foreign bodies or trauma, pinkeye, and in cattle, infectious bovine rhinotracheitis (IBR) and malignant catarrhal fever.

How do you prevent pink eye in goats?

Keeping the goat indoors or under a dense shade will help to reduce pain to the eyes. A patch over the eye can also be used to reduce sun glare. Keeping infected goats away for uninfected goats is the best prevention.

How do you get rid of pink eye in goats?

The treatment of choice for pinkeye is a parenterally administered course of antibiotics (oxytetracycline or trimethoprim sulpha) which should be repeated as necessary if signs persist.
