Abstract:
:The ongoing seventh cholera pandemic is attributed to Vibrio cholerae O1 El Tor biotype strains. Although antibiotic therapy ameliorates symptoms in patients and reduces pathogen transfer to the environment, multidrug resistance remains a major clinical threat. An O1 El Tor strain isolated from a patient in 1998 was intermediate or resistant to 13 antibiotics and could potentially produce extended-spectrum β-lactamase (ESBL), which is very rare in O1 strains. Using genome sequencing, three relevant genetic elements were identified in this strain: a hybrid SXT element (ICEVchCHN1307); a new IncA/C plasmid (pVC1307); and a chromosomal integron. Twenty antibiotic resistance genes were located on them, including blaTEM-1, blaCTX-M-14 and phenotypically silenced tetRA genes. These data elucidate the role of individual genetic components in antibiotic resistance and the accumulation of drug resistance genes in V. cholerae.
