Abortions in dromedaries (Camelus dromedarius) caused by equine rhinitis A virus

Knowles nick.knowles{at}bbsrc.ac.uk A virus was isolated from aborted dromedary ( Camelus dromedarius ) fetuses during an abortion storm in Dubai, United Arab Emirates. Laboratory investigations showed the causative agent to be indistinguishable from equine rhinitis A virus (ERAV), a picornavirus. Two pregnant dromedaries experimentally infected with the camel virus isolate both aborted and an identical virus was reisolated from both fetuses, thus confirming the diagnosis. The extremely high prevalence of antibody (>90 %) and the high titres recorded against ERAV in the dromedary herd clearly showed that ERAV does infect dromedaries. Unlike horses, where ERAV targets the upper respiratory tract, in dromedaries the target organ appears to be the genital tract. The GenBank/EMBL/DDBJ accession numbers for the sequences determined in this paper are EF204767–EF204772.
