Helminths of Two Species of Leopard Frogs (Amphibia: Ranidae) from Chiapas, Mexico

摘要

As a part of an amphibian survey from 2003 to 2010, specimens of leopard frogs (27 Rana cf. forreri and 15 Rana brownorum) from the state of Chiapas, Mexico, were collected and examined for helminths. Thirteen helminth species were collected from R. cf. forreri: 5 trematodes and 8 nematodes; the most prevalent helminth species was the nematode Cosmocerca parva and the most abundant was Proteocephalidae gen. sp. Eleven helminth species were collected from R. brownorum: 3 trematodes, 7 nematodes, and 1 acanthocephalan; the most prevalent species were Haematoloechus sp., Rhabdias cf. sphaerocephala, and Oxyascaris sp., and the most abundant was R. cf. sphaerocephala. Hosts in this study shared 3 helminth species: Haematoloechus sp., Oxyascaris sp., and Foleyellides striatus.
