Whole-Genome Sequencing of O1 El Tor Strains Isolated in Ukraine (2011) and Russia (2014).

Here, we present the draft whole-genome sequence of O1 El Tor strains 76 and M3265/80, isolated in Mariupol, Ukraine, and Moscow, Russia. The presence of various mutations detected in virulence-associated mobile elements indicates high genetic similarity of the strains reported here with new highly virulent variants of the cholera agent .
