Objective: To assess the potential routes of transmission of clinical enterotoxigenic Escherichia\udcoli (ETEC) from a patient in Southern Thailand.\udMethods: The fate of ETEC PSU192 was monitored in four potential ETEC vehicles (ice, acidic\udfood, pasteurization temperature and natural water) in different time intervals. Bacterial survival\udwas determined by surface plate count on MacConkey agar.\udResults: We clearly showed that ice, acidic food and natural water were able to behave as the\udpotential vehicles transmitting the clinical ETEC PSU192 to humans. While ETEC PSU192 was\uddeactivated under pasteurization temperature, suggesting that pasteurized milk could not act as\uda vehicle for ETEC transmission.\udConclusions: This is one of rare studies assessing the route of transmission of clinical ETEC\udthrough food and natural water in Thailand. Data clearly emphasized the potential routes\udof transmission of ETEC in this area. These findings will be of benefit for more appropriate\udprevention of massive losses by ETEC infection in Southern Thailand
