Via Eurosurveillance, a big story: Middle East respiratory syndrome coronavirus (MERS-CoV) serology in major livestock species in an affected region in Jordan, June to September 2013. The abstract:
Between June and September 2013, sera from 11 dromedary camels, 150 goats, 126 sheep and 91 cows were collected in Jordan, where the first human Middle-East respiratory syndrome (MERS) cluster appeared in 2012. All sera were tested for MERS-coronavirus (MERS-CoV) specific antibodies by protein microarray with confirmation by virus neutralisation. Neutralising antibodies were found in all camel sera while sera from goats and cattle tested negative. Although six sheep sera reacted with MERS-CoV antigen, neutralising antibodies were not detected.
And all the camels were in Zarqa governorate, where the first unrecognized MERS cases appeared in the local hospital. Since the camels were calves, the authors say in the discussion section, it may be that they had been recently infected—which could mean that MERS is endemic in Jordan and perhaps in other parts of the Middle East.
