摘要
目的了解近年来广州市海珠区副溶血性弧菌食物中毒分离株、散发腹泻病人监测分离株、外环境分离株的血清分型及耐药现状。方法 2011—2013年61株副溶血性弧菌,包括17株食物中毒菌株、27株散发腹泻病人菌株、17株外环境监测菌株,对其进行生化鉴定、血清分型及药敏试验。结果 17株食物中毒分离菌株,共分6个血清型,O3∶K6共12株(70.6%);27株散发腹泻病人分离菌株,共分10个血清型,O3∶K6共17株(63.0%);17株外环境分离菌株,共分11个血清型,其血清型分布分散。61株菌株出现两重耐药3株,三重耐药1株。结论广州市海珠区食物中毒、腹泻病人中主要流行的血清型是O3∶K6,不同来源的分离株存在不同程度的抗生素耐药。
Objective To study the current status of serotype and drug resistance in Vibrio parahaemolyticus in food poisoning, diarrhea patients and the environment in Haizhu district of Guangzhou. Methods 17strains from food poisoning, 27 strains from sporadic diarrhea patients and 17 strains from the environment were identified with biochemical and serotyping tests. Antibiotic resistance test of the isolates was further performed. Results Seventeen strains from food poisoning could be divided into 6 serotypes, and the prevalent serotype was O3： K6 （ 12/17, 70. 6% ）. Twenty-seven trains from diarrhea patients could be divided into 10 serotypes, and the prevalent serotype was 03： K6 （17/27, 63.0% ）. Seventeen strains from the environment could be divided into 11 serotypes, but the serotypes were scattered. In addition, there were three dual-resistantstrains, and one triple-resistantstrain in those 61 strains. Conclusion The strains were on different levels of antibiotic resistance, and the prevalent serotype was O3： K6 in Haizhu district of Guangzhou.
