A Brief Analysis of Antimicrobial Resistance Monitoring of Pet-derived Bacteria in Beijing in 2022
To understand the Antimicrobial resistance of pet-derived bacteria in beijing,the anal swabs of 50 samples of dogs and cats from four pet hospitals in Beijing were investigated in 2022.The Escherichia coli and Enterococcus were first isolated and identified by mass spectrometer,and then,the antimicrobial resistance characteristics of the isolated bacteria was analyzed by microbroth dilution method.Results showed that 25 strains of Escherichia coli and 25 strains of Enterococcus(14 strains of Enterococcus faecium and 11 strains of Enterococcus faecalis)were isolated.The two antibiotics with the highest antimicrobial resistance rate of Escherichia coli were tetracycline and ampicillin,and multi-antibiotic resistant bacteria accounted for 44%.The highest antimicrobial resistance rate of Enterococcus faecalis was sulfisoxazole,and the highest antimicrobial resistance rate of Enterococcus faecium was sulfisoxazole,cefoxitin and erythromycin.Multi-antibiotic resistant strains accounted for 100%of the total number of isolates.In summary,the problem of antimicrobial resistance of pet-derived Escherichia coli and enterococci in Beijing is relatively serious,indicating that the supervision and management of the use of pet antimicrobials need to be further strengthened.
