目的分析微创泌尿外科感染病原菌的具体分布情况与耐药性特征,为抗菌药物的应用以及临床感染预防提供指导。方法选取泌尿外科患者的资料进行分析,并在API检定方法与纸片扩散方式应用下,对样本中菌种做出鉴定,且判断病原菌药敏情况。结果取样本855例,分离病原菌320株,革兰阴性菌、革兰阳性菌与真菌分别为180株、125株、15株,大肠埃希菌分布最多;病原菌耐药性中,左氧氟沙星、青霉素G耐药率极高,都保持在50%以上。结论革兰阴性菌是微创泌尿外科感染的主要病原菌,其在耐药率上较高,临床治疗中医师应结合实际耐药性情况,合理选用抗菌药物,提高治愈率。
Objective To analyze the specific distribution and drug resistance characteristics of pathogenic bacteria in minimally invasive urological infection and provide guidance for the application of antibacterial drugs and prevention of clinical infection. Methods The data of urology patients were selected for analysis. The API strains and disk diffusion methods were used to identify the strains in the samples and determine the susceptibility of the pathogens. Results A total of 855 samples were collected and 320 pathogens were isolated. Gram-negative bacteria, Gram-positive bacteria and fungi were 180 strains, 125 strains and 15 strains, respectively. Escherichia coli was the most frequently distributed in the pathogenic bacteria. Levofloxacin, penicillin G Resistance rates are high, are maintained at 50%. Conclusions Gram-negative bacteria is the main pathogen of minimally invasive urological infection, which has a high resistance rate. In clinical practice, physicians should select appropriate antibacterial drugs and improve the cure rate according to the actual drug resistance.
