Experts say the new human coronavirus, if it causes SARS, probably arose when it managed to incorporate similar but foreign RNA, which, like DNA, can make up the genome or genetic code of microorganisms.
Human coronavirus NL63 was identified in 2004 in the Netherlands.
It could also, however, be a mutation of another human coronavirus.
A highly pathogenic human coronavirus causing respiratory disease emerged in the Middle East region in 2012.
It has been known that SARS coronavirus (SARS_CoV) is a novel human coronavirus and is responsible for SARS infection.
Significantly, compound 2 displayed selective antiviral activity (CC50 >3× EC50) towards human coronavirus (HCoV -NL63 and Middle East respiratory syndrome-coronavirus, but not severe acute respiratory syndrome-coronavirus.
Severe acute respiratory syndrome is a highly infectious upper respiratory tract disease caused by SARS-CoV, a previously unidentified human coronavirus.
Severe acute respiratory syndrome (SARS) is a highly contagious infectious disease which first emerged in late 2002, caused by a then novel human coronavirus, SARS coronavirus (SARS-CoV).
In this study, soluble recombinant human coronavirus OC43 (HCoV-OC43) NP was produced to examine the antigenicity of the HCoV-OC43 NP of betacoronavirus.
The nucleocapsid (N) gene of human coronavirus strain OC43 (HCoV-OC43) was amplified by reverse transcriptase-polymerase chain reaction, and cloned in pENTR™/D-TOPO® plasmid.
Human coronavirus HKU1 (HCoV-HKU1) is a recently identified coronavirus with a global distribution and known to cause mainly respiratory infections.
