目的 :为临床诊断和治疗前列腺炎提供细菌学依据。方法 :取前列腺液进行细菌培养和药物敏感性试验。结果 :前列腺炎的致病菌中以革兰氏阳性菌为主。革兰氏阳性菌以金黄色葡萄球菌居多 ,万古霉素和头孢唑啉对其有很好疗效 ;革兰氏阴性菌以大肠埃希氏菌居多 ,头孢呋辛和阿米卡星对其有很好疗效。结论 :对前列腺炎应在药敏试验指导下选用敏感性抗生素治疗。 Objective: To provide bacteriological basis for clinical diagnosis and treatment of prostatitis. Methods: Prostatic fluid was used for bacterial culture and drug sensitivity test. Results: Gram-positive bacteria were the main pathogens in prostatitis. Gram-positive bacteria to Staphylococcus aureus, vancomycin and cefazolin have a good effect on it; Gram-negative bacteria are mostly Escherichia coli, cefuroxime and amikacin to its Very good effect. Conclusion: Prostatitis should be treated with sensitive antibiotics under the guidance of drug sensitivity test.
