Journal Article 1999

Autor: Peter, T.F. Anderson, E.C. Burridge, M.J. Perry, Brian D. Mahan, S.M.

Three species of wild African ruminants. impala (Aepyceros melampus), sable (Hippotragus equinus, and tsessebe (Damaliscus lunatus), were experimentally inoculated with in vitro culture-derived Cowdria ruminantium organisms, the tick-borne causative agent of heartwater in domestic ruminants, to d...

Adult Amblyomma hebraeum ticks, the principle vector of heartwater (cowdriosis) of domestic ruminants in southern Africa, were collected in pheromone traps placed in Kruger National Park, an exclusively wildlife sanctuary in South Africa. These ticks transmitted Cowdria ruminantium, the rickettsi...

Journal Article 1999

Analysis of the transmission dynamics of Cowdria ruminantium, the tick-borne rickettsial agent of heartwater in ruminants, requires accurate measures of infection in vector populations. To obtain these, Amblyomma hebraeum ticks were collected at two heartwater-endemic locations in the lowveld and...

Conference Paper 2000

Autor: Peter, T.F. O'Callaghan, C.J. Medley, G.F. Mahan, S.M. Perry, Brian D.

Heartwater is a disease of high mortality in domestic ruminants (cattle, sheep and goats) in sub-Saharan Africa and in the Caribbean. An intracellular rickettsia, Cowdria ruminantium, is the cause of the disease and is transmitted by ticks of the genus Amblyomma. Losses due to heartwater are high...
