Seroepidemiological studies for the detection of antibodies against 8 infectious diseases in dairy dromedaries of the United Arab Emirates using modern laboratory techniques - Part II.

摘要

A total of 1119 dromedary sera (578 dams, and 541 calves) were tested for eight different infectious diseases (viral diseases (Rift Valley fever, Bluetongue, Equine Rhinitis A virus, Camel pox, Bovine Viral Diarrhea and Mucosal Disease, and Enzootic Bovine Leucosis), bacterial disease (leptospirosis), and parasitic disease (neosporosis)) using commercially available competitive ELISAs (cELISA) or other tests (serum neutralization test and microscopic agglutination test). Results revealed that no antibodies were detected for Enzootic Bovine Leukosis. Antibodies were detected for Rift Valley Fever (0.35%), Bluetongue (21%), Equine Rhinitis A virus (5.7%), Camelpox (66%), Bovine Viral Diarrhea (1.6%), leptospirosis (12%) and neosporosis (13.7%). It is concluded that cELISAs are reliable tests and can be used in dromedaries. However, more research is needed when using indirect ELISA to minimize false positives and negatives.
