Abstract

The comparative susceptibility of 622 recent clinical isolates of anaerobic bacteria to minocycline, doxycycline, and tetracycline was determined by an agar-dilution technique. In addition to Bacteroides fragilis, a variety of other anaerobic bacteria was resistant to achievable blood concentrations of tetracycline (55% inhibited by 6.25 mug/ml) and doxycycline (58% inhibited by 2.5 mug/ml). In contrast, minocycline was significantly more active (P < 0.05) than both doxycycline and tetracycline, and 70% of strains were inhibited by achievable blood concentrations of this antibiotic (2.5 mug/ml). The enhanced activity of minocycline was particularly striking for Peptococcus asaccharolyticus, P. magnus, P. prevotii, Peptostreptococcus anaerobius, and Bacteroides melaninogenicus. Further evaluation of the clinical efficacy of minocycline against anaerobic infections is indicated.

摘要

采用琼脂稀释技术测定了622株近期临床分离的厌氧菌对米诺环素、多西环素和四环素的敏感性。除脆弱拟杆菌外,多种其他厌氧菌对四环素(6.25μg/ml抑制55%)和多西环素(2.5μg/ml抑制58%)可达到的血药浓度耐药。相比之下,米诺环素的活性显著高于多西环素和四环素(P<0.05),70%的菌株可被该抗生素可达到的血药浓度(2.5μg/ml)抑制。米诺环素对不解糖消化球菌、大消化球菌、普氏消化球菌、厌氧消化链球菌和产黑色素拟杆菌的增强活性尤为显著。有必要进一步评估米诺环素抗厌氧菌感染的临床疗效。
