目的了解海产品中副溶血性弧菌污染情况及其耐药性,为海产品保鲜提供科学依据。方法用现场随机抽样和细菌检验方法,对某海岛海产品进行了抽样调查和检测。结果随机抽样247份,检出44份溶血性弧菌阳性,阳性率为17.8%。贝类检出副溶血性弧菌阳性率显著高于鱼类。从检出的副溶血性弧菌中选出9株进行了药敏试验,对奈啶酮酸、庆大霉素、头孢唑啉等11种抗生素全部敏感,对青霉素和氨苄青霉素全部耐药。检出2株副溶血性弧菌神奈川现象阳性,占4.55%。结论本次调查的海产品中副溶血性弧菌检出率和神奈川现象阳性率均比较低,所检出的株菌对多数抗生素比较敏感,只要加强管理措施此类食物中毒具有很好的可控性。
Objective To understand the pollution and drug resistance of Vibrio parahaemolyticus in seafood and provide a scientific basis for the preservation of seafood. Methods Random sampling and bacterial test methods were used to sample and test the seafood of a certain island. Results A total of 247 samples were randomly selected and 44 were positive for Vibrio parahaemolyticus. The positive rate was 17.8%. The positive rate of Vibrio parahaemolyticus detected by shellfish was significantly higher than that of fish. Nine strains of Vibrio parahaemolyticus were selected for susceptibility testing. All of them were sensitive to eleven antibiotics such as naltrexone, gentamicin and cefazolin, and all were resistant to penicillin and ampicillin. Two strains of Vibrio parahaemolyticus were found positive in Kanagawa, accounting for 4.55%. Conclusion The positive rates of Vibrio parahaemolyticus and Kanagawa in seafood surveyed in this survey are relatively low. Most of the strains tested are sensitive to most antibiotics, so long as the management measures are taken to strengthen such food poisoning, Controllable.
