Clonal origins of Vibrio cholerae O1 El Tor strains, Papua New Guinea, 2009-2011

Emerg Infect Dis. 2011 Nov;17(11):2063-5. doi: 10.3201/eid1711.110782.


We used multilocus sequence typing and variable number tandem repeat analysis to determine the clonal origins of Vibrio cholerae O1 El Tor strains from an outbreak of cholera that began in 2009 in Papua New Guinea. The epidemic is ongoing, and transmission risk is elevated within the Pacific region.
