目的探讨复发性尿路感染患者细菌检验及药物敏感(药敏)检验的结果。方法 218例复发性尿路感染患者,均实施细菌培养及药敏检验,分析病原菌分布情况,并探讨其耐药性。结果本组患者共检出菌株数为206株,检出146株革兰阴性菌,检出率为70.9%(146/206),检出60株革兰阳性菌,检出率为29.1%(60/206)。革兰阴性菌对喹诺酮类、氨基糖苷类、第三代头孢菌素类等抗菌药物有着较高的耐药性,对亚胺培南耐药性较低;革兰阳性菌对左旋氧氟沙星、克林霉素耐药性较高。结论革兰阴性菌是复发性尿路感染患者常见致病菌,且不同病原菌对不同抗菌药物敏感性也存在差异,需引起高度关注。
Objective To investigate the results of bacterial test and drug susceptibility test in patients with recurrent urinary tract infection. Methods A total of 218 patients with recurrent urinary tract infection were subjected to bacterial culture and drug susceptibility tests. The distribution of pathogens and the drug resistance were analyzed. Results A total of 206 strains of bacteria were detected in this group of patients, of which 146 were Gram-negative bacteria. The detection rate was 70.9% (146/206), 60 Gram-positive bacteria were detected, the detection rate was 29.1% 60/206). Gram-negative bacteria have higher resistance to quinolones, aminoglycosides, third-generation cephalosporins and other antibacterials, and have lower resistance to imipenem. Gram-positive bacteria are more sensitive to levofloxacin Star, clindamycin higher resistance. Conclusion Gram-negative bacteria are common pathogenic bacteria in patients with recurrent urinary tract infection, and different pathogens have different sensitivity to different antibiotics, which should be paid more attention.
