抗生素的过量使用与细菌耐药性关系研究

目的：探讨过量使用抗生素与细菌耐药性的关系,为临床上合理使用抗生素提供依据。方法：2005年1月～2010年12月,对我所G-感染菌药敏试验进行连续观察。病原菌培养按常规方法培养分离,获纯菌后鉴定到种,共培养出337株致病菌（真菌除外）。结果：选取的305例细菌感染患者使用第三代头孢菌素居第一位（41.39%）,其次为喹诺酮类（29.80%）;5种细菌对头孢呋肟的耐药性最高。从305例患者标本中共分离培养出337株病原菌,依次为铜绿假单胞菌183株、肺炎克雷伯菌70株、大肠埃希菌46株、阴沟杆菌22株、金黄色葡萄球菌16株。结论：临床过量应用抗生素不合理可使细菌产生耐药性,G-菌对头孢一、二代及青霉素有较高耐药性,而对三代头孢菌素、喹诺酮类耐药性逐渐增加。

Research on the relationship between antibiotic overuse and bacterial resistance

Objective: To evaluate relationship between overuse of antibiotics and bacterial resistance,to provide a reasonable basis for the clinical use of antibiotics.Methods: From January 2005 to December 2010,continuous observation of bacterial susceptibility testing during the G-infections were given in our institute.Culture for pathogens isolated culture according to conventional methods were identified to species after pure germ,337 pathogenic bacteria were cultured(except fungi).Results: The use of third-gener...
