Signs of theileriosis are those associated with anaemia and include: pale membranes, depression, lethargy, lack of appetite, exercise intolerance, (lagging behind the mob) downer cows that do not respond to treatment and in some instances cattle may collapse and die if stressed or forced to move or run. In districts where theileria is commonly found (endemic areas) and most adult cattle are immune, calves should be closely inspected when they are 6-12 weeks old introduced cattle should be examined closely when they have been in the district for three to eight weeks. Bovine anaemia caused by theileria orientalis group p 3 vector control reducing tick numbers should reduce the likelihood of cattle becoming infected.
Two experiments were carried out in which parvaquone was used to treat experimentally-induced acute clinical east coast fever infections in the first experiment, infections with theileria parva parva (kiambu 5) were induced by applying infected rhipicephalus appendiculatus ticks or by inoculation of triturated infected-tick stabilate. Theileriosis caused by the hemoprotozoan pathogen theileria parva still ranks first among the tick-borne diseases of cattle in sub-saharan africa (minjauw and mcleod, 2003) organisms in the genus theileria are found in many wild and domesticated animals (reviewed in norval et al, 1992 .
