Antibodies to Cowdria ruminantium
in Mozambican goats and cattle detected by immunofluorescence using endothelial cell culture antigen.
phagocytophilia Amblyoma Cowdriosis Cowdria ruminantium
variegatum Anaplasmosis Anaplasma marginale R.
The tick vectors of Cowdria ruminantium
(Ixodoidea, Ixodidae, genus Amblyomma) and their distribution.
The tick is a pest of economic and pathogenic concern since it readily infests cattle (Semtner & Hair 1973), and is the vector of Cowdria ruminantium Cowdry (the causative agent of Heartwater disease) (Uilenburg 1982) and Rickettsia parkeri (the causative agent of newly described spotted fever) (Paddock et al.
Because Amblyomma maculatum is the primary vector of Rickettsia parkeri and the secondary vector of Cowdria ruminantium, additional studies on the distribution of this tick should be investigated as well as its relation to human diseases.
