Vibrio cholerae O1 Isolate with Novel Genetic Background, Thailand–Myanmar
Figure. . . Relationships among MS6, Vibrio cholerae O1 strain, isolated in Thailand in 2008, and other V. cholerae O1 strains based on 15 housekeeping genes referenced in Salim et al. (10). Boldface indicates the MS6 strain. The mutational (m) and recombinational (r) changes with gene names are marked on the branches (r ≠ r2). Numbers in parentheses represent the year of isolation. DNA gyrase subunit B gene (gyrB) of MS6 is 22 nt differences from that of the seventh pandemic clone. Two genes of MS6, malP and pepN, exhibit novel sequence types based on results of a BLAST search (http://blast.ncbi.nlm.nih.gov/Blast.cgi).
