Ticks are particularly important as vectors of pathogens affecting domestic animals, causing diseases such as babesiosis, anaplasmosis, theileriosis, cowdriosis, ehrlichiosis, hepatozoonosis, cytauzoonosis, borreliosis, tularaemia and rocky mountain spotted fever.
Besides causing blood loss and decreased milk or meat production, ticks transmit a number of diseases, including babesiosis, anaplasmosis, and cowdriosis. The Nguni cattle of Southern Africa have been reported to be resistant to tickborne diseases [60].

More commonly known as cowdriosis, the infection leads to a wasting condition which kills animals.
The eradication of anaplasmosis, babesiosis and cowdriosis in the French Overseas Departments is also supported (Euro 500,000).EU funds will also be used to eradicate the most serious viral diseases in pigs such as classical and African swine fever and swine vesicular disease.
vaccination against cowdriosis and dosing once every fortnight in the rainy season and once a month in the dry season.
