Distribution and drug resistance analysis of food bovne Gram-negative bacteria in Beijing
Objective To understand the distribution and resistance of foodborne Gram-negative bacteria in Beijing.Methods Foodborne Gram-negative bacteria isolated from food monitoring networks,emergency expanded sampling,and food poisoning in Beijing from 2020 to 2021 were collected,and micro broth dilution method was used to detect the sensitivity of foodborne Gram-negative bacteria to 15 commonly used antibiotics.Results 101 strains of foodborne Gram-negative bacteria were derived from 12 genera of Enterobacteriaceae,Vibrionaceae,Pseudomonadaceae and Moraceae,with the top 3 detected being Aeromonas hydrophila/Guinea pig,Serratia liquefaciens and Enterobacter cloacae.101 strains of foodborne Gram-negative bacteria showed resistance to 15 antibiotics,ranging from 0.99%to 76.24%.41 strains of multidrug-resistant organisms were detected,with a detection rate of 40.59%.Among them,triple-resistant bacteria were the most common,and there were a total of 37 resistance profiles.2 strains of imipenem resistant foodborne Gram-negative bacteria were detected.Conclusion Foodborne Gram-negative bacteria are widely distributed and have the characteristics of universal resistance,with severe multidrug resistance,including carbapenem insensitive foodborne gram-negative bacteria.
