Fig. 5. .Representation of the conservation of the initial part of the spike protein. Each line corresponds to a different conservation cut-off value, where “spike-trans” corresponds to the original spike protein reference sequence (YP_009724390.1), and the lines below “spike.C60” to “spikeC100” correspond to the conservation cut-off in 60 to 100% of the isolates. Each column corresponds to a position in the protein. Regions that did not pass a specific cut-off are represented by a “-”. Asterisks at the bottom highlight 100% conserved positions in all evaluated isolates.
