了解牛屠宰厂来源的单增李斯特菌的耐药性情况.采用牛屠宰厂来源的的55株单增李斯特菌为研究对象，采用Kirby-Bauer法检测对16种抗生素的耐药情况.所检55株单增李斯特菌株对青霉素G、诺氟沙星、复方新诺明等不耐药，对头孢噻吩、多粘菌素B、头孢噻肟、依诺沙星的耐药率分别为1.82％、25.45％、36.36％、38.18％，耐3种以上抗生素的有44株，其中耐3种抗生素的27株（49.09％），耐4种抗生素的17株（30.90％）.单增李斯特菌对4种抗生素存在耐药情况，并且存在不同程度的多重耐药情况的菌株，今后应加强对单增李斯特菌的污染情况和耐药性检测，以保证食品安全和人类健康.

[ Objective]Listeria monocytogenes isolates from beef cattle processing plants were examined for antibiotic resist-ance.[Methods]Antimicrobial susceptibility to 16 kinds of antibiotics of 55 Listeria monocytogenes were determined by Kirby-Bauer method,respectively. [ Results]The 55 strains of Listeria monocytogenes were sensitive to penicillin G,norfloxacin, cotrimoxazole etc. Among the 55 Listeria monocytogenes isolates,1. 82% were resistant to cephalothin,followed by resistant to polymyxin B(25. 45%),cefotaxime(36. 36%),enoxacin(38. 18%). 44 strains were resistant to more than 3 kinds of anti-biotic,among them 27 strains were resistant to 3 kinds of antibiotic(49. 09%),17 strains were resistant to 4 kinds of antibiotic (30. 90%).[ Conclusion]Listeria monocytogenes isolates were resistant to 4 antibiotics. Listeria monocytogenes appeared multidrug resistance in different degree. So the contamination and drug resistance of Listeria monocytogenes should be moni-tored to ensure food safety and human health in the future.
