Draft genomes of four enterotoxigenic Escherichia coli (ETEC) clinical isolates from China and Bangladesh
BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is an important pathogen that causes childhood and travelers’ diarrhea. Here, we present the draft genomes of four ETEC isolates recovered from stool specimens of patients with diarrhea in Beijing, China and Dhaka, Bangladesh, respectively. RESULTS...

description | BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is an important pathogen that causes childhood and travelers’ diarrhea. Here, we present the draft genomes of four ETEC isolates recovered from stool specimens of patients with diarrhea in Beijing, China and Dhaka, Bangladesh, respectively. RESULTS: We obtained the draft genomes of ETEC strains CE516 and CE549 isolated in China, and E1777 and E2265 isolated in Bangladesh with a length of 5.1 Mbp, 4.9 Mbp, 5.1 Mbp, and 5.0 Mbp, respectively. Phylogenetic analysis indicated that the four strains grouped with the classical Escherichia coli phylogenetic groups A and B1 and three of them including a multi drug-resistant Chinese isolate (CE549) belonged to two major ETEC lineages distributed globally. The heat stable toxin (ST) structural gene (estA) was present in all strains except in strain CE516, and the heat labile toxin (LT) operon (eltAB) was present in all four genomes. Moreover, different resistance gene profiles were found between the ETEC strains. CONCLUSIONS: The draft genomes of the two isolates CE516 and CE549 represent the first genomes of ETEC reported from China. Though we revealed that ETEC is uncommon in Beijing, China, however, when it does occur, multi-drug resistance and ESBL positive isolates might pose a specific public health risk. Furthermore, this study advances our understanding of prevalence and antibiotic resistance of ETEC in China and adds to the number of sequenced strains from Bangladesh. |
