Betacoronavirus 1

provided by wikipedia EN

Betacoronavirus 1 is a species of coronavirus which infects humans and cattle.[4][5] The infecting virus is an enveloped, positive-sense, single-stranded RNA virus and is a member of the genus Betacoronavirus and subgenus Embecovirus.[6] Like other embecoviruses, it has an additional shorter spike-like surface protein called hemagglutinin esterase (HE) as well as the larger coronavirus spike protein.[7][8]

Coronavirus

Le betacoronavirus 1 est une espèce de coronavirus qui infecte les humains et le bétail[2]. Le virus infectant est un virus à ARN monocaténaire enveloppé à polarité positive, et appartient au genre Betacoronavirus et au sous-genre Embecovirus[3]. Il possède, comme d'autres embécovirus, une protéine de surface en forme de pic plus courte supplémentaire, appelée hémagglutinine estérase (HE)[4],[5].

Il comprend notamment les membres suivants[6] :
