Abstract
Forty-three Rana catesbeiana, 120 Rana clamitans, and 5 Ranapalustris from the Wills Creek drainage system in Coshocton County, OH, were examined for helminths. The sample of/?, catesbeiana included 24 tadpoles, 3 metamorphosing individuals and 16 adults; the sample of/?, clamitans included 18 tadpoles, 40 metamorphosing individuals and 62 adults; the sample of/?, palustris included 5 adults. Tadpoles were infected with one species of nematode, Gyrinicola batrachiensis. Prevalence (% of animals infected) of G. batrachiensis in /?. catesbeiana and /?. clamitans tadpoles was 4% and 11%, respectively. Metamorphosing individuals contained no helminths. Adult frogs were infected with 1 species of trematode, Haematoloechus longiplexus, 1 species of cestode, Ophiotaenia gracilis, and 3 species of nematodes, Cosmocercoides variabilis, Rhabdias ranae, and Physaloptera sp. Prevalence of helminths in adult frogs included//, longiplexus in 6% of the/?, catesbeiana and 5% of the/?, clamitans', O. gracilis in 8% of the/?, clamitans; C. variabilis in 6% of the/?, catesbeiana, 18% of the/?, clamitans, and 20 % of the R. palustris; R. ranae in 13% of the/?, clamitans; and Physaloptera sp. in 2% of the/?, clamitans.
