广东省蛇类曼氏裂头蚴感染分析

为了掌握广东省食用蛇类曼氏裂头蚴感染情况。2014~2015年,从广州、肇庆、惠州和韶关等地农贸市场共采集赤链蛇、铅色蛇、赤链华游蛇和异色蛇等4种常见食用蛇样本114条,并对这些蛇类样本的曼氏裂头蚴感染情况进行了解剖学检查。结果显示,曼氏裂头蚴感染个体32条,总感染率为28.07%,共发现裂头蚴243条；赤链蛇、铅色蛇、赤链华游蛇和异色蛇的感染率分别为93.33、14.58、38.46和4.00%；个体平均感染强度分别为：12.27、0.35、1.58和0.04个/条；肌肉、皮下组织和体腔三个部位的寄生率分别为80.25%、16.46%、3.29%。研究结果表明,广东省食用蛇类曼氏裂头蚴感染比较普遍,对蛇类消费人群的健康构成潜在威胁。

Investigation of Spirometra mansoni Infection in Snakes from Guangdon Province

To survey the Plerocercoid (Pseudophyllidea, Diphyllobothriidae) infection in snakes from different areas of Guangdong Province. From 2014~2015, a total of 114 snakes of 4 species were examined in in four cities (Guangzhou, Zhaoqing, Huizhou and Shaoguan), including Lycodon rufozonatum, Hypsiscopus plumbea, SinonatrixSannularis, and Xenochrophis piscator. Overall, 243 worms of Spirometra were isolated from 32 snakes, accounting for 28.07% of the total examined snake samples. The infection rates of the 4 examined species (Lycodon rufozonatum, Hypsiscopus plumbea, SinonatrixSannularis, and Xenochrophis piscator) were 90.33%, 14.58%, 38.46%, and 4.00%, respectively, while the mean densitys of infection were 12.27, 0.35, 1.58 and 0.04 worms per snake. Most (80.25%) of the spargana located in muscular tissue, 16.46% in subcutaneous tissue, and 3.29% in the coelomic cavity. The results showed that Spirometra mansoni infection in snakes is common in Guangdong Province, and eating snakes has great health risk.
