摘 要：The prevalence of helminths in the wild frogs was investigated in Hunan province,People’s Republic of China from April 2008 to June 2009.A total of 601 frogs,mainly 20kg to 40kg,were collected from 19 representative geographical locations in Hunan province and then dissected at laboratory to examine for the presence of helminths using a helminthologica *** 601 frogs included 469 Rana nigromaculata,91 marsh frog,29 Rana tigrina rugulosa and 12 Rana *** collected worms were counted and identied to species according to normal methods and descriptions.A total of 7 helminth species were found representing 3 phyla,4 classes,5 families and 7 genera. Some wild frogs were infected by more than one helminth species.7.4%of the examined Rana nigromacnlata and 18.6% of marsh frog were infected with Archiacanthocephala;13.4%of the Rana nigromacnlata,5.5%of marsh frog,75%of Rana limnocharis and 48.2%of Rana tigrina rugulosa with Spirometra erinaceieuropaei sparganosis;12.8%of Rana nigromaculata, 5.5%of marsh frog and 3.4%of Rana tigrina rugulosa with Encysted Metacercaria of trematode;1.2%of Rana nigromaculata with trematode;and 8.3%of Rana nigromaculata,50%of Rana limnocharis and 3.3%marsh frog with Celiac filaria;1.1%of Rana nigromaculata and 8.3%of Rana limnocharis with Capillaria obsignata;and 18.7%of Rana nigromaculata,2.2%of marsh frog and 16.7%of Rana limnocharis with nematode that mainly located in Thigh *** infective rate in Spirometra erinaceieuropaei sparganosis is the highest amonge the frogs.2 of the 7 wild frog helminths,Spirometra erinaceieuropaei sparganosis and trematode,are also transmissible to humans,that can cause severe clinical human diseases,posing signicant public health *** results of the present investigation have conducted that it is high time to take effective and efficient measure to put an end to the helminth infections in wild frogs in Hunan province and other parts of China.
