清远市市售蛙类曼氏裂头蚴感染情况调查

Spirometra mansoni sparganum infection in frogs from Qingyuan city markets

目的了解清远市市售蛙类曼氏裂头蚴的感染状况。方法从市场购买人工养殖的虎纹蛙和野生泽蛙,逐只解剖查找曼氏裂头蚴。结果检查100只人工饲养的虎纹蛙,均为阴性;检查107只野生泽蛙,曼氏裂头蚴感染率为41.12%(44/107),平均感染度为6.55条/只;不同大小泽蛙曼氏裂头蚴感染率差异有统计学意义(χ2=7.40,P<0.01);曼氏裂头蚴可在蛙体内任何部位的肌肉寄生,其中以大腿部肌肉寄生最为常见,占62.85%(181/288)。结论清远市市售人工养殖的虎纹蛙未发现曼氏裂头蚴,野生蛙类体内曼氏裂头蚴感染率较高,野生蛙类为重点防范对象,开展健康教育,预防曼氏裂头蚴病的工作十分必要。

Objective To investigate the infection condition Spirometra mansoni Sparganum in frogs from Qingyuan city markets. Methods Rana tigrina and wild Rana limnocharis were bought from markets in Qingyuan city, and were dissected for finding Sparganum mansoni. Results 100 Rana tigrina were dissected; the infection rate was zero. 107 wild R.limnocharis were dissected, with an infection rate of 41.12%（44 / 107）, and with an average infection of 6.55 Sparganum per frog.There were significant differences on the infection rates of Sparganum in different sizes of R.imnocharis（χ2=7.40,P 〈0.01）;Sparganum mansoni can lodge in any muscle of frogs, and the thigh muscle was the most common parasitic location, accounted for 62.85%（181 / 288）. Conclusion There was no Sparganum mansoni in Rana tigrina from Qingyuan city markets. The infection rate of sparganum of Spirometra mansoni in wild frogs was high, so the wild frogs were the main precautionary subjects. It is necessary to carry out health education for preventing sparganosis mansoni.
