Abstract
The gastrointestinal tracts, lungs, and urinary bladders from 77 Bufo microscaphus, 61 Bufo woodhousii, and 8 of their hybrids were examined for helminths. One species of trematode (Glypthelmins quieta), 1 species of cestode (Distoichometra bufonis), and 5 species of nematodes (Aplectana incerta, A. itzocanensis, Rhabdias americanus, Physaloptera sp., and Physocephalus sp.) were found. The greatest prevalence (41%) and mean intensity (231.7) were recorded for Aplectana incerta in Bufo woodhousii. It appears hybrids harbor fewer parasites than either parent species.
