Occurrence in Mexico, 1998–2008, of Vibrio cholerae CTX + El Tor carrying an additional truncated CTX prophage

Abstract: The seventh cholera pandemic caused by Vibrio cholerae O1 El Tor (ET) has been superseded in Asia and Africa by altered ET possessing the cholera toxin (CTX) gene of classical (CL)

“…Los dos primeros fueron por V. cholerae serotipo Inaba y los otros dos por V. cholerae serotipo Ogawa. A través de la epidemiologia molecular se identificó rápidamente que dichas cepas eran las mismas del brote de 1991 a 2001 5,15 . La cepa InDRE3140 se identificó como la causante del brote de cólera de la región de La Huasteca en 2013; las pruebas bioquími-cas, serológicas y microbiológicas identificaron esta cepa como V. cholerae O1 serotipo Ogawa biotipo El Tor.…”

“…Microbiological, molecular, and phylogenetic analyses of V. cholera isolated from both clinical and environmental samples during 1998-2008 confirm important genetic events, namely predominance of ET over CL and altered ET in Mexico (Nair et al, 2006). Although altered ET is predominantly associated with cholera globally, progression of CTX positive V. cholerae ET with truncated CTX prophage to the predominant pathogen causing endemic cholera in Mexico may prove to be yet another key historical point in the global epidemiology of cholera (Alama et al, 2014).…”

“…Data here reported suggest that the Inaba serotype and the seafood were the factors where the toxin producing bacteria were predominant. Actually in Mexico, the analysis of environmental samples suggests a permanent circulation of toxin producing bacteria [15][16][17]; thus, the DOT-ELISA here described could be a very useful rapid diagnostic tests designed to enhance a rapid response in epidemiological conditions.…”
