Ehrlichia ruminantium is an obligately intracellular proteobacterium which causes a disease known as heartwater or cowdriosis in some wild, and all domestic, ruminants. The organism is transmitted by ticks of the genus Amblyomma, and it is of serious economic importance wherever the natural vectors occur, an area which includes all of sub-Saharan Africa, and several islands in the Caribbean. Th...

متن کاملEhrlichia ruminantium: an emerging human pathogen?
To the Editor: Ehrlichia ruminantium, transmitted by ticks of the genus Amblyomma, causes heartwater in ruminants in subSaharan Africa, Madagascar and some Caribbean islands, but there are no authenticated reports that the organism can cause disease in non-ruminants or humans. No reliable vaccine is available and infected animals frequently die before treatment with tetracyclines can be initiat...
متن کاملDevelopment of a polyclonal competitive enzyme-linked immunosorbent assay for detection of antibodies to Ehrlichia ruminantium.
A polyclonal competitive enzyme-linked immunosorbent assay (PC-ELISA) is described for detection of antibodies to Ehrlichia (Cowdria) ruminantium by using a soluble extract of endothelial cell culture-derived E. ruminantium as the antigen and biotin-labeled polyclonal goat immunoglobulins as the competitor. For goats, the diagnostic sensitivity and specificity were both 100% with a cutoff of 80...
