Livestock Pinkeye (Keratoconjunctivitis)

Pinkeye is an inflammation of the surface of the eye and of the inner surfaces of the surrounding conjunctival tissue. This often produces redness in the tissue, hence the name.

Pinkeye may affect one or both eyes. Redness and swelling of the tissue surrounding the eye and excessive tears are noticeable side effects. Pinkeye is often caused by a Chlamydial agent, but may be caused by bacteria or mycoplasma organisms as well.  If left untreated, it may damage the cornea by ulceration; this can lead to permanent blindness. Pinkeye can spread by direct contact or via flies. Reported outbreaks have affected over 90% of the flock.  

Treatment: Tetracycline antibiotic ointment is placed in the eye everyday for several days. The Chlamydial agent in pinkeye is especially sensitive to this drug. Sever outbreaks may require the subconjunctival injection of antibiotics by a veterinarian to provide more prolonged treatment. If the lower lid rolls in directly onto the eye, it must be corrected by a veterinarian before causing permanent damage to the cornea.

Separate infected animals, reduce dust and control flies to reduce new cases.

Liver Fluke in East Friesian Dairy Sheep

The adult stage of this parasite lives in the bile ducts in the liver of sheep.

A very small number can pose a detrimental effect on the host. Larvae hatch eggs passed in the feces, but they must be ingested by a snail to move to the next stage of development. Flukes are usually found in damp meadows or wetlands where snails are present.

Prevention can be directed at drying up wetlands or fencing sheep away from them. Two available medications, Clorsulon and Albendazole are effective if given after the first of January when the larvae have developed into adults in the liver. After 2-4 years of use the number of eggs and larvae on the pasture should be greatly reduced and pose little threat. Continued use of these medications is necessary to prevent resurgence.

Have a wonderful weekend~
