Quantitative Analysis of Colistin-Resistant Escherichia coli in Retail Meat from Local Vietnamese Markets

The spread of drug-resistant bacteria via food has contributed to the dissemination resistant among humans. However, status contamination with bacteria, particularly quantitative level in food, not yet been well elucidated. In this study, abundance colistin-resistant Escherichia coli meat samples was quantified understand origin available local Vietnamese markets. Fifteen each chicken and pork purchased from markets were assessed for presence E. mobile colistin resistance gene, mcr. results showed that 40% (6/15) 66% (10/15) samples, respectively, contaminated coli. median levels 1.8 × 10 4 id="M2"> 4.2 3 CFU/g, respectively. phylogenetic analysis isolates a sample mix multiple phylogenetical clones may have multiplied during sale. This is first study quantify samples.
