目的探讨老年慢性细菌性前列腺炎的病原菌分布与耐药性,为临床提供疾病诊断及治疗依据。方法采集老年慢性前列腺炎患者的前列腺液进行细菌培养和体外药敏试验,并进行统计分析。结果 316例老年慢性前列腺炎患者的前列腺液中共检出病原菌205株,其中革兰阳性菌123株,占60.0%;以金黄色葡萄球菌为主。革兰阴性菌82株,占40.0%;以大肠埃希菌为主。前列腺炎病原菌对常用抗菌药物已产生了耐药性,检出耐甲氧西林葡萄球菌(MRS)35株,占葡萄球菌属总数的34.7%;产ESBLs病原菌占肠杆菌科细菌总数的35.6%。结论老年慢性细菌性前列腺炎具有难治性和迁延性,应加强病原菌耐药性检测,提高治愈率。
Objective To investigate the distribution and drug resistance of pathogens in elderly chronic bacterial prostatitis and to provide the basis for the diagnosis and treatment of the disease. Methods Prostate fluid from elderly patients with chronic prostatitis was collected for bacterial culture and drug susceptibility testing in vitro. Statistical analysis was performed. Results A total of 205 pathogenic bacteria were detected in prostatic fluid of 316 elderly patients with chronic prostatitis, of which 123 strains were Gram-positive bacteria, accounting for 60.0%. Staphylococcus aureus was the main factor. Gram-negative bacteria 82 strains, accounting for 40.0%; Escherichia coli-based. Prostatitis pathogens commonly used antibiotics have been drug-resistant, methicillin-resistant Staphylococcus aureus (MRS) 35 strains, accounting for 34.7% of the total number of Staphylococcus; ESBLs-producing pathogens accounted for 35.6% of Enterobacteriaceae bacteria. Conclusion Senile chronic bacterial prostatitis is refractory and persistent, and the detection of drug resistance of pathogens should be strengthened to improve the cure rate.
