Detection of rabies antibody by ELISA and RFFIT in unvaccinated dogs and in the endangered Simien jackal (Canis simensis) of Ethiopia

Abstract

Varying levels of rabies antibody have been detected both by Enzyme Linked Immunosorbent Assay (ELISA) and Rapid Fluorescent Focus Inhibition Test (RFFIT) in the sera collected from wild and domestic canids in the Bale Mountains National Park (BMNP) of Southern Ethiopia. Rabies antibody was detected in 80% (8 out of 10) of domestic dog samples, 13.3% (2 out of 15) of Simien jackal samples and in one common jackal. Rabies virus was isolated from one dog in an area where contact with the Simien jackal could possibly occur. All samples examined from wild rodents as possible reservoir hosts for rabies were found negative. The presence of large proportion of susceptible Simien jackals in the population should be a cause of great concern in saving this endangered species from the ravages of rabies.
