| 摘要: |
| 为初步了解上海市场蛇寄生虫的感染情况,剖检了来自上海市场罚没的2种19条蛇,其中赤链蛇(Dinodon rufozonatum)9条、大王蛇(Elaphe carinata)10条,分别取血液涂片,依序检查体表、皮下、肌肉、心脏、肺脏、肝脏、胃、肠道等组织器官,收集检获的寄生虫,显微镜初步观察.结果显示:在19条蛇均未检出外体寄生虫、吸虫和棘头虫,在皮下和体内检出线虫和绦虫,在血液中检出肝簇虫(Hepatozoon),蛇的寄生虫感染率为100%.线虫、绦虫、肝簇虫在赤链蛇的检出率分别为77.88%、100%、0,在大王蛇的检出率全部为100%.从19条蛇共检获线虫192条、绦虫(裂头蚴)1236条,其中69.79%的线虫和86.55%的绦虫来自大王蛇.按检出的脏器统计,93.20%的绦虫来自皮下与肌肉,65.63%的线虫来自胃.调查结果表明,上海市场两种蛇的寄生虫感染率高、感染强度大,其中检出的裂头蚴为人畜共患寄生虫,吃蛇皮与蛇肉、吞蛇胆存在感染寄生虫的极大风险.因此,保护蛇类等野生动物,也是保护人类自身. |

| Abstract: |
| To investigate the infective status of parasites in snakes from Shanghai,19 snakes from 2 species ( 9 Dinodon rufozonatum and 10 Elaphe carinata) confiscated from the market were dissected.The viscera (body,subcutaneous,muscles,heart,lungs,liver,stomach,intestinal organs) and blood smears of the snakes were examined.The parasites from these viscera were collected and observed by microscope.The results showed nematodes,tapeworms and Hepatozoon were found,but no ectoparasites,trematodes and acanthocephalan.The parasitic infection rate of snakes checked was 100%.The infection rate of nematodes,tapeworms and Hepatozoon were 77.88%,100%,0 in Dinodon rufozonatum and 100%,100%,100% in Elaphe carinata, respectively.A total of 192 nematodes and 1236 tapeworms were collected in 19 snakes,and 69.79% of nematodes and 86.55% of tapeworms were from Elaphe carinata.According to the viscera,93.20% of tapeworms were found in subcutaneous and 65.63% of nematodes in stomach.The results indicated the parasitic infection rate and intensity of snakes from Shanghai market were very high.Sparganum mansoni found in this investigation was zoonotic parasite,and it is easy to infect humans through eating snake skin,meat and gall.Therefore,protecting wild animals like snakes is also to protect human themselves. |
