小儿夏季急性感染性腹泻致病菌及药敏试验分析

Analysis on the pathogen and drug sensitivity of infantile acute infective diarrhea in summer

目的:了解本市夏季小儿急性感染性腹泻主要致病菌及对常用抗生素敏感性的变化.方法:对1994～1997年5～8月14岁以下急性感染性腹泻住院患儿大便进行培养,94～96年用S.S培养基,97年加用麦康凯及山梨醇培养基,分离出致病菌249株,进一步作病原菌分离和菌群鉴定,并作11种抗生素药敏试验.结果:福氏痢疾杆菌是主要致病菌,痢特灵的敏感率最高(70%以上),氟哌酸和先锋V的敏感性有所下降,丁胺卡那霉素和庆大霉素敏感率明显回升至50%以上,沙门氏菌和绿脓杆菌是少见的致病菌,最敏感的抗生素是丁胺卡那霉素.

ve To study the main pathogen of infantile acute infective diarrhea and their drug sensitivity change to some commonly used antibiotics in summer Taiyuan. Methods The bloody purulent stool of the inpatients Who are under 14 years and with acute infective diarrea in May to August of 1994 to 1997 was cultured. The S. S culture medium was used from 1994 to 1996, Maikangkai and sorbitol were added in 1997. A total of 249 strains of pathogen were seperated. The pathogen seperation and flora identification were done. The drug sensitivity test of the pathogen to 11 kinds of antibiotics was done. Results Shigella flexmeri was the main pathogen. The sensitive rate of the pathogen to furazolidone was the highest( >70% ), but that to norfloxacin and cefazolin decreased to some extent, and that to amikacin and gentamycin rose again to more than 50%. Salmonella and pseudomonas aeruginosa were rare pathogen.The most sensitive antibiotic was amikacin.
