MERS Coronavirus in Dromedary Camel Herd, Saudi Arabia
نویسندگان
چکیده
A prospective study of a dromedary camel herd during the 2013-14 calving season showed Middle East respiratory syndrome coronavirus infection of calves and adults. Virus was isolated from the nose and feces but more frequently from the nose. Preexisting neutralizing antibody did not appear to protect against infection.

To assess the temporal dynamics of Middle East respiratory syndrome coronavirus (MERS-CoV) infection in dromedary camels, specimens were collected at 1-2 month intervals from 2 independent groups of animals during April 2013-May 2014 in Al-Ahsa Province, Saudi Arabia, and tested for MERS-CoV RNA by reverse transcription PCR. Of 96 live camels, 28 (29.2%) nasal swab samples were positive; of 91 ...

1 Middle East Respiratory Syndrome Coronavirus (MERS-CoV) has been persistent in 2 the Middle East region since 2012. Abundant scientific evidence showed that dromedary 3 camels are the primary host of the virus. Majority of human cases (i.e. 75% or 88%) are 4 due to human-to-human transmission, while the others are due to camel-to-human transmis5 sion. Mathematical modelling of MERS-CoV camel-...

متن کاملCo-circulation of three camel coronavirus species and recombination of MERS-CoVs in Saudi Arabia.
Outbreaks of Middle East respiratory syndrome (MERS) raise questions about the prevalence and evolution of the MERS coronavirus (CoV) in its animal reservoir. Our surveillance in Saudi Arabia in 2014 and 2015 showed that viruses of the MERS-CoV species and a human CoV 229E-related lineage co-circulated at high prevalence, with frequent co-infections in the upper respiratory tract of dromedary c...

In fact, we mentioned in our paper [2] in detail that the cycle threshold (Ct) values in nasal and conjunctival swabs of the five MERS-CoV reverse transcriptionquantitative polymerase chain reaction (RT-qPCR) positive Omani camels ranged from as low as 15.74 to 36.29, indicating a high viral load in the former. Our results were confirmed in a recent report by Raj et al. [3], who demonstrated an...
