Primary production environment is considered as reservoir of Escherichia coli contamination of produce. E. coli is classified into eight phylogroups which differ in ecological niches, evolutionary history, and phenotypic properties. To understand the population genetic structure and composition of E. coli in primary production environments in Metro Manila, Philippines, a total of 80 E. coli recovered from irrigation water, soil, vegetables, and feces of cat, carabao, chicken, dog, and goat were allocated into distinct phylogroups based on the presence and absence of genetic markers. Results showed that the most prevalent phylogroup was B1 (71.3%), followed by A (18.6%), D (6.3%), B2 (1.3%), E (1.3%), and an unknown phylogroup (1.3%). The most prevalent genetic marker was arpA, followed by TspE4.C2, yjaA, and chuA. The carbapenem resistance of 24 E. coli isolates representing different phylogroups was also evaluated. Intriguingly, all isolates exhibited uniform susceptibility. This is the first report to provide insights into the phylogroup structure and composition, as well as carbapenem resistance of E. coli from primary production in the Philippines, which highlights possible source of and solution for gastrointestinal and enteric diseases.
