Genome sequence and comparative analysis of a Vibrio cholerae O139 strain E306 isolated from a cholera case in China.

ABSTRACT:

Background

Vibrio cholerae is a human intestinal pathogen and V. cholerae of the O139 serogroups are responsible for the current epidemic cholera in China. In this work, we reported the whole genome sequencing of a V. cholerae O139 strain E306 isolated from a cholera patient in the 306th Hospital of PLA, Beijing, China.

Results

We obtained the draft genome of V. cholerae O139 strain E306 with a length of 4,161,908 bps and mean G + C content of 47.7%. Phylogenetic analysis indicated that strain E306 was very close to another O139 strain, V. cholerae MO10, which was isolated during the cholera outbreak in India and Bangladesh. However, unlike MO10, strain E306 harbors the El Tor-specific RS1 element with no pre-CTX prophage (VSK), very similar to those found in some V. cholera
