浙江省台州市农村地区鼠形动物自然感染4种病原体的调查

Investigation of natural infection of four pathogens in rodents in rural area of Taizhou, Zhejiang

    摘要
  • 摘要:
      目的   了解浙江省台州市农村地区鼠形动物自然感染4种常见病原体的情况，为鼠传疾病防制提供依据。
      方法   2020年9 — 12月在台州市三门县和天台县农村地区用夹（笼）夜法捕获鼠形动物，所获标本分别经分类鉴定和登记后，无菌操作采集鼠肝、脾、肺、肾等样本，应用实时荧光定量PCR法检测汉坦病毒、新型布尼亚病毒、钩端螺旋体、恙虫病东方体4种病原体。
      结果   在2个县监测点共捕获鼠形动物7种167只，总捕获率为6.13%，其中黑线姬鼠（84只，50.30%）、黄毛鼠（31只，18.56%）、褐家鼠（25只，14.97%）为优势鼠种，2个县鼠种构成相似。 167份组织样本中钩端螺旋体阳性18份（10.78%），汉坦病毒阳性1份（0.60%），恙虫病东方体阳性2份（1.20%），新型布尼亚病毒未检出。 从褐家鼠、黑线姬鼠、黄胸鼠、黄毛鼠中均有检出钩端螺旋体，其阳性率分别为8.00%、14.29%、14.29%、9.68%，差异无统计学意义。 仅从黑线姬鼠中检出汉坦病毒，仅从黄毛鼠中检出恙虫病东方体。 白腹巨鼠、小家鼠、臭鼩鼱中未检出4种病原体。 黑线姬鼠中存在钩端螺旋体和汉坦病毒混合感染，混合感染率为0.60%（1/167）。
      结论   台州市农村地区鼠形动物中存在多种病原体感染，不同鼠种病原体检出率不同，需进一步加强鼠传疾病防制，降低人群感染风险。

     

    Abstract:
      Objective  To understand the infection status of four pathogens in rodents in rural area of Taizhou, Zhejiang, and provide evidence for the prevention and control of rodent-borne infectious disease.
      Methods  From September to December in 2020, rodents were captured by night trapping method in rural areas of Sanmen and Tiantai counties, Taizhou. The liver, spleen, lung and kidney of the rodents were collected aseptically after classification and identification. Hantavirus, new Bunia virus, Leptospira and Orientia tsutsugamushi were detected by real-time PCR.
      Results  A total of 167 rodents of 7 species were captured in the two counties, and the overall capture rate was 6.13%. Among the rodents captured, Apodemus agrarius (84, 50.30%), Rattus losea (31, 18.56%) and Rattus norvegicus (25, 14.97%) were predominant. The composition of rodent species was similar among the two counties. In 167 tissue samples, 18 were positive for Leptospira (10.78%), 1 was positive for Hantavirus (0.60%), 2 were positive for Orientia tsutsugamushi (1.20%), but no new Bunia virus was detected. Leptospira was detected in Rattus norvegicus, Apodemus agrarius, Rattus flavipectus and Rattus losea, and the positive rates were 8.00%, 14.29%, 14.29% and 9.68% respectively. Hantavirus was only detected in Apodemus agrarius. Orientia tsutsugamushi was only detected in Rattus losea. No pathogens were detected in Rattus edwardsi, Mus musculus and Suneus murinus. Apodemus agrarius was co-infected with Leptospira and Hantavirus, and the rate of co-infection was 0.60% (1/167).
      Conclusion  Rodents in rural area of Taizhou carried a variety of pathogens. The detection rate of pathogens in different rodents was different. It is necessary to strengthen the prevention and control of rodent-borne infectious disease to reduce the risk of human infection.
