Full genome sequence of Vibrio cholerae O1 strain, MS6. Vibrio cholerae MS6

Vibrio cholerae are found in the aquatic environment in different parts of the world. They are facultatively anaerobic, asporogenous, motile, curved or straight gram-negative rods. More than 200 serogroups of V. cholerae have been recognized to date, but only serogroups O1 and O139 are known to cause cholera in humans of epidemic and pandemic proportions. We obtained a V. cholerae O1 El Tor isolate from a diarrheal patient, and was named MS6. Multilocus sequence typing analysis revealed that strain MS6 was most closely related to the US Gulf Coast clone; however, two housekeeping genes of MS6 exhibit novel sequence types. This analysis represents an important step toward the understanding of the evolutional history and of the genetic basis underlying pathogenicity in cholera organism.
