老年女性泌尿系统感染菌种分布及耐药性分析

Bacterial species distribution and drug resistance in senile women with urinary tract infections

目的分析广东省茂名市区老年女性泌尿系统感染致病菌种类分布及耐药情况，为当地临床合理使用抗生素提供依据。方法对225例患有泌尿系统感染的老年女性中段尿样本进行细菌培养鉴定和耐药性测定。结果茂名市区老年女性泌尿系统感染致病菌有地区性表现，革兰氏阴性杆菌占57．6％，革兰氏阳性球菌占30．5％，真菌占8．6％。有9例同时感染两种致病菌（占4．0％）。各种致病菌对不同抗生素表现多重耐药性。结论对归属地区老年女性泌尿系统感染患者治疗前进行致病菌培养和药敏试验，可为临床有效用药提供准确依据。

Objective To investigate distribution and drug resistance of pathogenic bacterial species among senile women with urinary tract infections in Maoming urban areas of Guangdong province, so as to provide a basis for rational use of antibiotics in clinic in this areas. Methods The midstream urine samples of 225 senile women who were suffering from urinary tract infections were examined for bacterial culture and identification and determination of drug resistance. Results In pathogenic bacterial species, there was an unique regional performance in Maoming： gram-negative bacilli accounted for 57. 6%, while gram-positive cocci accounted for 30. 5% and fungus accounted for 8.6%. 9 women were infected with two pathogens, accounting for 4. 0%. A variety of pathogens presented multiple antibiotic resistance. Conclusion The pathogenic bacterial culture and sensitivity test before treatment can provide a reliable basis for clinical medication for senile women with urinary tract infections in the urban areas of Maoming city.
