    Abstract:

    Objective To evaluate the antimicrobial resistances of Li.steria mon,ocytogen,en,s isolated from food in China. Methods The susceptibility of 1 069 strains of Listeria mon,ocytogen,es isolated from foocl t0 15 antibiotics currently used in veterinary and human therapy were tested. Susceptibility tests were performed by using broth mic:rodilution susceptihility test in Clinical and Laboratory Standards Institute. Results Among the 1 069 tested strains, the resistance to one kind of antibiotics was 33 (3. 1% ) , to two kinds of antibiotics was 38 (3. 6% ) and to three kinds of antibiotics was 3 (0. 28% ). The foods with the highest antibiotic resistance rate were frozen ric:e and flour products. Among the 22 provinces, Cansu, Jilin and Fujian were the three top provinces with the highest antibiotic resistance rates of 27. 3% , 20. 4% and 17. 4% , respectively. Conclusion Foodborn Listeria m,onotogenen,.s strains in China are susceptible to the antibiotics commonly used in veterinary and clinical medicine. Considering the emergence of antimicrobial resistance of Lisiteria monocytogen,es is slow, continued surveillance and management of the clinical and veterinary use of antibiotics to reduc:e the resistant strains is important.
