Description
The dissemination of Extraintestinal pathogenic Escherichia coli (ExPEC) in food is a critical concern for human health and food safety. The present study is the first to systematically examine the diverse plant-origin foods such as cucumber, carrot, tomato, radish, chilli, fenugreek, coriander, peppermint, spring onion, cabbage, and spinach for the presence of ExPEC or specific putative ExPEC pathotypes with an in-depth assessment of their phylogenetics, virulence, and drug resistance. A total of 77 (15.9 %) ExPEC isolates were recovered from 1780 samples of the diverse plant-origin foods of distinct environments. Specific putative ExPEC pathotypes such as Uropathogenic E. coli (UPEC, 23.3 %) and Septicemia-associated E. coli (SEPEC, 24.6 %) were identified among ExPEC isolates. The Clermont revisited new phylotyping method revealed the varied distribution (1–27 %) of specific putative ExPEC pathotypes …
