摘　　要：目的了解北海市腹泻人群及海(水)产品致泻性弧菌污染情况,为北海市制订防控策略提供依据。方法按照《〈全国霍乱监测方案2012〉广西实施细则》和《北海市霍乱监测方案(2012年版)》(北卫防[2012]76号)等文件要求,对2013-2015年腹泻人群和海(水)产品致泻性弧菌进行监测,监测时间为每年5-10月,分析致泻性弧菌在北海市的流行状况。结果 2012-2015年共采集腹泻人群标本1 126份,共检测出副溶血弧菌6份,河弧菌1份,气单胞菌9份,弧菌总阳性率为1.42%,监测样本均未检出霍乱弧菌。2013-2015年3年间腹泻人群弧菌阳性率分别为1.79%、2.14%、0.28%,差异无统计学意义(χ~2=5.108,P=0.078)。2013-2015年3年间海(水)产品弧菌阳性率分别为27.85%、44.44%、75.42%,差异有统计学意义(χ~2=46.879,P=0.001),2015年海(水)产品副溶血弧菌阳性率分别高于2014年和2013年(P<0.05),有逐年升高趋势(χ_(趋势)~2=45.305,P=0.001)。结论 2013-2015年北海市腹泻人群及海(水)产品虽未检出霍乱弧菌,但海(水)产品副溶血弧菌的检出率有逐年上升趋势,应继续加强监测,及时发现样品中的指示菌株,对预防和控制霍乱的发生及流行有重要意义。Objective To investigate the contamination status of diarrheagenic Vibrio in the diarrhea population and marine （ a- quatic I products in Beihai City so as to provide evidence for formulating prevention and control strategies in Beihai City. Meth- ods According to the requirements of the National Plan for Cholera Surveillance, 2012 （ Guangxi Implementation Plan） and the Beihai Plan for Cholera Surveillance （ Beihai Health and Prevention 2012, No.76） , diarrheagenic Vibrio in the diarrhea population and marine { aquatic） products was monitored from May to October in 2013-2015. And the prevalence status of diarrheagenic Vib- rio in Beihai City was analyzed. Results A total of 1,126 diarrhea stool specimens were collected during 2012-2015. Vibrio parahemolyticus was detected in 6 specimens, Vibrio fluvialis in 1 specimen, and Aeromonas in 9 ones. The total positive rate of Vibrio was 1.42%, but no Vibrio cholera was detected in the monitored specimens. The positive rates of Vibrio in the diarrhea popu- lation in 2013, 2014 and 2015 were 1.79%, 2.14% and 0.28% respectively, without statistically significant differences （X2= 5. 108, P= 0.078）. The positive rates of Vibrio in the marine （aquatic） products in 2013, 2014 and 2015 were 27.85%, 44.44% and 75.42% respectively, showing no statistically significant differences （X2= 46.879, P= 0.001）. The positive rate of Vibrio para- , X2 hemolyticus in 2015 was higher than those in 2014 and 2013 （ both P〈0.05） showing an increasing tendency year by year （ tendncy = 45. 305, P= 0.001）. Conclusions Although no Vibrio cholera is detected in the diarrhea population and marine （aquatic） products in Beihai City during 2013-2015, the detection rate of Vibrio parahemolyticus in the marine （aquatic） products shows an increasing tendency year by year. Continuously intensifying the monitoring and timely detecting the indicative strains in specimens are significantly important to prevent and control the occurrence and prevalence of cholera.
