Abstract (AI)
SXT-related integrating conjugative elements (ICEs) became prevalent in Asian Vibrio cholerae populations after V. cholerae O139 emerged. Here, we describe an SXT-related ICE, ICEVchMex1, in a Mexican environmental V. cholerae isolate. Identification of ICEVchMex1 represents the first description of an SXT-related ICE in the Western Hemisphere. The significant differences between the SXT and ICEVchMex1 genomes suggest that these ICEs have evolved independently.
Key Findings
1
ICEVchMex1 is an SXT-related integrating conjugative element identified in a Mexican environmental Vibrio cholerae isolate.
2
SXT-related ICEs are not restricted to Asian V. cholerae populations and occur in New World environmental isolates.
3
Substantial genomic differences between ICEVchMex1 and previously described SXT elements suggest independent evolutionary histories.
4
This finding represents the first reported SXT-related ICE in the Western Hemisphere.
