Abstract

We describe the isolation and sequencing of Middle East respiratory syndrome coronavirus (MERS-CoV) obtained from a dromedary camel and from a patient who died of laboratory-confirmed MERS-CoV infection after close contact with camels that had rhinorrhea. Nasal swabs collected from the patient and from one of his nine camels were positive for MERS-CoV RNA. In addition, MERS-CoV was isolated from the patient and the camel. The full genome sequences of the two isolates were identical. Serologic data indicated that MERS-CoV was circulating in the camels but not in the patient before the human infection occurred. These data suggest that this fatal case of human MERS-CoV infection was transmitted through close contact with an infected camel.

摘要

我们描述了从中东呼吸综合征冠状病毒（MERS-CoV）中分离和测序的骆驼和一名患者的情况，该患者在与有鼻漏的骆驼密切接触后死于实验室确诊的 MERS-CoV 感染。从患者和他的九只骆驼中的一只采集的鼻拭子均为 MERS-CoV RNA 阳性。此外，从患者和骆驼中分离出了 MERS-CoV。两种分离株的全基因组序列完全相同。血清学数据表明，在人类感染发生之前，MERS-CoV 在骆驼中传播，但不在患者中传播。这些数据表明，这例致命的人类 MERS-CoV 感染是通过与受感染的骆驼密切接触传播的。
