A test of 25 genetically diverse isolates of Bacillus anthracis was conducted to determine their susceptibility to seven clinically relevant antimicrobial agents. Etest strips (AB BIODISK, Solna, Sweden) were used to measure the MICs for the isolates. Using the National Committee for Clinical Laboratory Standards MIC breakpoints for staphylococci, three isolates were found to be resistant to penicillin and five were found to be resistant to cefuroxime. The penicillin-resistant isolates were negative for beta-lactamase production. Continued surveillance of B. anthracis field isolates is recommended to monitor antimicrobial susceptibility.
对25株基因多样的炭疽芽孢杆菌分离株进行了测试,以确定它们对七种临床相关抗菌剂的敏感性。使用Etest试纸条(AB BIODISK,瑞典索尔纳)测量分离株的最低抑菌浓度(MIC)。根据美国国家临床实验室标准委员会针对葡萄球菌的MIC断点,发现三株分离株对青霉素耐药,五株对头孢呋辛耐药。耐青霉素的分离株β-内酰胺酶产生呈阴性。建议持续监测炭疽芽孢杆菌野外分离株,以监测抗菌药物敏感性。
