title: Heartwater. The artificial transmission of Cowdria ruminantium in domestic ruminants and mice.
abstract: The artificial transmission of Cowdria ruminantium with infected blood, organ homogenates, peritoneal macrophages, tick stabilate and tissue culture cells is discussed. Organ homogenates prepared from the myocardium, spleen, kidneys and liver of diseased animals are commonly used to infect mice. The efficacy of organ homogenates as a source of C. ruminantium depends on factors such as the route of inoculation and the heartwater isolate used. Heartwater is artificially transmitted with infected tick stabilate, haemocytes, rectal ampules and hypodermal homogenates. The infectivity of saliva collected from Amblyomma hebraeum female ticks was very low compared to the ground-up suspensions prepared from the same group of ticks.
