连云港海域副溶血性弧菌的分布状况及危害性评估

Study of the Pollution by Vibrio parahaemolyticus in Different Sea Area in the City of Lianyungang and its Otential Dangerous

对连云港周边不同海域的海水及海产品中的副溶血性弧菌(Vibrio parahaemolyticus,Vp)进行分离,对检出菌株进行溶血性及耐药性检测。菌株检出率78%,溶血素阳性率68%,文蛤浸养感染率及死亡率20%～30%;耐药性检测结果表明,其对GN、SXT、TE、CAZ、CTX、CRO、CI、DO和NOR较为敏感,耐药率低于10%;对FR和AMP的耐药率在60%以上。连云港海域内及海产品中均存在副溶血性弧菌的污染,其中TRH型毒素分布较多。对海水养殖行业及人体健康具有潜在危险性。

Understand the distribution of the Vibrio parahaemolyticus in the sea around the city of lian yun gang and that distribution in the marine product. Then study the toxicity and the drug tolerance of them. Methods ： study the Vibrato parahaemolyticus, which were collected from salt water in different sea area or form different marine products in the city of Lian yun gang. The extracted samples were measured and analyzed for their haemolysin and drug resistance. The detection rate of the bacterium was 78% ; the positive rate of haemolysin was 68% ; the infection rate and death rate of the cultural meretrix was 20% - 30% ; the result of drug resistance showed that they were more sensitive to GN,SXT,TE,CAZ,CTX,CRO,CI,DO and NOR. The drug resistance rate is below 10%. While the rate of FR and AMP is above 60%. Conclusions ：the salt water and marine products in different sea area in the city of lian yun gang are both polluted with Vibrio parahaemolyticus. The toxin of TRH type exists on wider scale. They were potentially dangerous to both aquicuhure in the sea and the human health.
