目的:通过调查初步明确巴贝虫在温州市鼠形动物中分布状况及其传播媒介的存在状况,为进一步评估温州市居民感染巴贝虫病风险及巴贝虫病防治研究提供基础资料。方法:随机抽取4个县(市、区),在每个县(市、区)设1~3个调查点,采用鼠笼法调查鼠形动物种群构成,现场采集血液制作血涂片进行姬氏染色镜检查找巴贝虫,并对采集到的抗凝血标本进行巴贝虫检测。同时对捕获到的鼠形动物体表蜱进行梳检鉴定。结果:4个县(市、区)共捕获鼠形动物710只,发现巴贝虫阳性标本71份,阳性率为10.00%,其中鹿城区阳性率最高为53.77%,不同鼠形动物阳性率有所不同,其中社鼠阳性率最高28.57%。蜱标本中未发现巴贝虫阳性标本。结论:温州市鼠形动物携带巴贝虫阳性率较高,虽然媒介中未检测到阳性标本,但居民仍存在较高的感染风险,特别是野外作业人群。
OBJECTIVE: To investigate the distribution of Babesia pestis in Wenzhou rat and the existence of its vector by preliminary investigation, providing the basic information for further study on the risk of Babesiosis and the prevention and treatment of Babesiosis in Wenzhou. Methods: Four counties (cities and districts) were randomly selected, and 1 to 3 investigation points were set up in each county (city and district). Squirrels were used to investigate the population structure of the rodent animals. Papanicolaou examination to find Babesia, and collection of anti-clotting specimens for Babesia insect detection. At the same time, the captured mouse-shaped ticks were examined by combing. Results: A total of 710 mouse-shaped animals were captured in 4 counties (cities and districts). 71 positive samples of Babesia were found, the positive rate was 10.00%. The highest positive rate was 53.77% in Lucheng District. The positive rate of different mouse-shaped animals was The difference is that the highest positive rate of rats is 28.57%. No positive samples of Babesia were found in ticks. CONCLUSION: The positive rate of rodents carrying babacons in Wenzhou is relatively high. Although no positive samples are detected in the vectors, residents still have a high risk of infection, especially in field work.
