“Background Integrative and conjugative elements (ICEs) are self-transmissible mobile genetic elements that mediate horizontal gene Quisinostat supplier transfer between bacteria [1]. ICEs share certain features of phages, transposons and plasmids. But unlike these elements, ICEs integrate into and replicate as part of their host chromosomes, and can be transferred

via conjugation [1, 2]. ICEs and related elements can constitute a large proportion of bacterial chromosomes [3], and bestow a wide range of phenotypes upon their host with carried gene cassettes [4]. The first described ICEs-related elements were Tn916 from Enterococcus faecalis in 1980 [5] and CTnDOT from Bacteroides thetaiotaomicron in 1988 [6]. To date, a variety of ICEs have been classified into several families, and have been reported in diverse EPZ-6438 purchase Gram-positive and Gram-negative bacteria [1, 7], among which the SXT/R391 family were identified in Vibrionaceae isolates of clinical and environmental origins [8–10]. Vibrionaceae are Gram-negative, mesophilic and chemoorganotrophic

bacteria, which belong to γ-proteobacteria. They are virtually ubiquitous in aquatic environments, including estuaries, marine coastal waters and sediments, and aquaculture settings worldwide [11]. Globally water-borne infectious diseases are one of the major contributors to disease burden and mortality [12]. Pathogenic Vibrio cholerae and Vibrio parahaemolyticus are serious human food-borne pathogens, causing cholera epidemics and diarrheal disease, respectively, and continue to be prevalent particularly in developing countries with disputable sanitary conditions [13]. The Lepirudin SXT element was originally discovered in V. cholerae O139, the first non-O1serogroup of V. cholerae, which gave rise to epidemic cholera in India and Bangladesh in early 1990s [14]. Unlike E1 Tor O1 strains of V. cholerae, the O139 stain was identified to harbor characteristic pattern of resistance to sulfamethoxazole, trimethoprim, streptomycin and furazolidone, which was carried on a ~100 kb self-transmissible SXT element [14]. Comparative sequence analysis revealed closer genetic relationship between the SXT and R391 element (89 kb) that was identified in Providencia rettgeri isolate in South Africa in 1972 [15, 16].
