PRJDB5076 Genome sequence of Environmental Vibrio cholerae O1 To understand the genetic diversity of environmental Vibrio cholerae, four O1strains isolated in the Northern Vietnam had been sequenced. They are isolated between 2013 and 2015, and all of them did not encode the major virulence factors ctxA and ctxB.
