为了解广东省食用蛙类曼氏裂头蚴感染情况，2013年—2015年，从广州、肇庆和韶关等地区农贸市场共采集虎纹蛙、黑斑侧褶蛙、泽陆蛙、沼蛙和棘胸蛙等5种常见食用蛙样本1304只，并对这些蛙类样本的曼氏裂头蚴感染情况进行剖检。结果显示，曼氏裂头蚴感染个体148只，总感染率为11．35％，共发现裂头蚴553条；沼蛙、黑斑侧褶蛙、泽陆蛙、虎纹蛙和棘胸蛙的感染率分别为3．61％、13．68％、3．11％、25．59％和2．93％；个体平均感染强度分别为1．44、3．41、1．43、4．48、1．16条／只；肌肉、体腔和皮下组织三个部位的寄生率分别为89．69％、6．87％和3．44％。结果表明，广东省食用蛙类曼氏裂头蚴感染比较普遍，对蛙类消费人群的健康构成潜在威胁。%To survey the plerocercoid (Pseudophyllidea,Diphyllobothriidae)infection in frogs from different areas of Guangdong province,from 2013-2015,a total of 1 304 frogs of 5 species were examined in in three cities (Guangzhou,Zhaoqing and Shaoguan),including Hoplobatrachus chinensis ,Pelophylax nigromacu-latus ,Fej ervarya multistriata ,Boulengerana guentheri ,and Quasipaa spinosa .Overall,553 worms of Spi-rometra were isolated from 148 frogs,accounting for 11.35% of the total examined frog samples.The infec-tion rates of the 5 examined species (Hoplobatrachus chinensis ,Pelophylax nigromaculatus ,Fej ervarya multistriata ,Boulengerana guentheri ,and Quasipaa spinosa )were 3.61%,13.68%,3.11%,25.59% and 2.93%,respectively,while the mean densitys of infection were 1.44,3.41,1.43,4.48 and 1.16 worms per frog.Most (89.69%)of the spargana located in muscular tissue,6.87% in subcutaneous tissue,and 3.44%in the coelomic cavity.The results showed that S.mansoni infection in frogs is common in Guangdong province,and eating frogs has great health risk.
