Escherichia coli hyperepidemic clone ST410-A harboring blaCTX-M-15 isolated from fresh vegetables in a municipal market in Quito-Ecuador

Abstract:

Dissemination of Extended spectrum β-lactamases (ESBL) Enterobacteriaceae is a major medical threat. Vegetables and fruits, which are usually consumed raw, are a very suitable pathway for the spread of these bacteria from farm-to-fork. However, limited information exists regarding resistant bacteria and epidemic clones that are disseminated in vegetables and tap water in South America. We processed a total of 90 samples in triplicate of nine typically consumed raw vegetables from a central municipal market, and tap water samples were processed from twenty-one locations in Quito, Ecuador. The samples were analyzed for total coliforms and ESBL Enterobacteriaceae contamination using the dilution filtration method. ESBL Escherichia coli isolates were phenotypically and genotypically characterized. The water was free of Enterobacteriaceae, but all the vegetables and fruits (except for blackberries …
