Heartwater, caused by Ehrlichia ruminantium, is one of the most important tick-borne diseases of livestock in Africa. It is a major obstacle for the introduction of high-producing animals into Africa, 1 causing mortality rates up to 90%. For instance, in cattle, a mortality rate of 60% due to heartwater is common, and in merino sheep, it may rise up to 80%. 2 For the Southern African Development Community (Angola, Botswana, Malawi, Mozambique, South Africa, Swaziland, Tanzania, and Zimbabwe), the losses are estimated around 47.6 millions of dollars per year. These economical losses are mainly due to mortality, diminution of productivity in farming systems, and cost of treatment (use of antibiotics and acaricides).
