title: The complete genomic analysis of an imported Vibrio cholerae from Myanmar in southwest China.
abstract: We sequenced and analyzed an imported Vibrio cholerae from Mynamar in 2011 by using whole genome sequencing method in Yunnan Province, southwest China. Other 3 isolates of V. cholerae in Yunnan were also sequenced for comparing purpose. Illumina Hiseq2500 was used and the sequencing results were assembled and annotated. The comparative genomic analysis was also performed with 101 reference strains from China and abroad. The results showed the imported V. cholerae (YN2011004) had two chromosomes and one plasmid; chr1 contained 2727 predicted genes, and 958 genes for chr2. Phylogenomic tree results showed YN2011004 belonged to the seventh pandemic strain, clustered into wave 3 and clade 3B. The strain had the highly homology with SN083 and 4remapscaff isolated in 2010 from other parts of China, and clustered with SN117, VC50 remapscaff, VC57 remapscaff and SN034. These references V. cholerae mostly isolated from coastal areas of China in 2008. For the other 3 strains' comparison, it suggested that V. cholerae in 1990s in Yunnan had the close relationship with the prevalence of cholera in Southeast Asia. Therefore, we thought that the cholera in Yunnan was consistent with the epidemic trend of China, being the "sink" for external source and also acted as a "source" for spread. Moreover, we considered that the imported V. cholerae from Myanmar in 2011 actually was the exported strain from China, and it provided us a new sight for the bacterial change and evolution.
