Anaplasmosis

8022

12/30/01

Causes:
Anaplasmosis is quite rare in goats; but when an infection occurs, it is usually caused by invasion of red blood cells by the blood parasite (rickettsial) Anaplasma ovis. In cattle, the disease is caused by A. marginale or A. centrale. Transmission is through insect vectors, especially ticks and flies. There is also some evidence that it can be transmitted to the fetus in the womb ("in utero").
Symptoms:

The important symptoms are fever, anemia and icterus (jaundice or yellowing of the mucous membranes will be obvious). In cattle, the severity of the disease is directly related to age, with adults showing the greatest difficulty. Additionally, a drop in milk production, weight loss, depression, dehydration, constipation and lack of appetite may be observed. Some animals which recover remain weak and emaciated through life.
Other diseases to consider:

Anthrax.
Difficulty rating:   [bold type applies]

DEFINITELY a matter for your veterinarian
Do these things until you can reach the vet
You may be able to handle it youself; for the moderately experienced
Fairly simple; give it a try!

Treatment options:

LA200® and "TLC" along with a lot of help from your vet and rigid control of insects.
Prevention

The disease can be spread at dehorning and castration; always use sanitary procedures and try to avoid bleeding. Also, always try to keep flies and ticks to a minimum.
