2021年至2023年8月济南海关口岸入境截获病媒生物监测分析

Monitoring and Analysis of Vector Interceptions at Jinan Customs Port from 2021 to August 2023

目的 掌握济南海关辖区各口岸截获的入境病媒生物情况,为防范入境病媒生物提供科学依据。方法 2021-2023年8月济南海关辖区各口岸实施入境病媒生物监测,包括鼠类、成蚊、蚊虫幼虫(蛹)、成蝇、蝇幼虫(蛹)、蜚蠊,并进行病原体实验室检测。结果 在口岸入境船舶和航空器、集装箱、货物、快件及邮包中均发现鼠类阳性指征;在口岸入境截获成年蚊虫336只,分别为淡色库蚊266只、三角喙库蚊36只、中华按蚊34只,黄热病、登革热、疟疾、基孔肯亚热等病原体实验室检测均为阴性;截获866只蜚蠊均为德国小蠊,经实验室检测检出大肠埃希菌、肠球菌属、不动杆菌属、魏斯氏菌属、光滑念珠菌等。结论 通过加强对口岸入境交通运载工具的病媒生物监控,可以及时发现并处理携带病原体的病媒生物,防止疾病通过口岸传入和流行,对保障国民健康和经济生产意义重大。

Objective To provide scientific basis for preventing entry vector organisms by mastering the situation of entry vector organisms intercepted at various ports under the jurisdiction of Jinan Customs.Methods We made monitoring of inbound vector organisms,including rodents,adult mosquitoes,mosquito larvae,adult flies,fly larvae,cockroaches,and conducting pathogen laboratory tests on them,at various ports under the jurisdiction of Jinan Cus-toms from 2021 to August 2023.Results We found positive signs of rodents in incoming ships and aircraft,con-tainers,goods,express parcels,and postal parcels at the port.We intercepted 336 adult mosquitoes at the port of en-try,including 266 culex pipiens pallens,36 culex triangularis,and 34 Anopheles sinensis,the pathogen laboratory tests of which such as yellow fever,dengue fever,malaria,and chikungunya fever were all negative.We intercepted 866 cockroaches,all of which were German cockroaches,the pathogen laboratory tests of which such as Escherichia coli,Enterococcus,Acinetobacter,Weissella and Candida glabrata were detected.Conclusion It is possible to promptly detect and handle vector organisms carrying pathogens,and prevent the spread of diseases through ports,by strengthening the monitoring of vector organisms on inbound transportation vehicles at ports.This is of great sig-nificance for safeguarding national health and economic production.
