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 spec ies of cestode (Distoichometra bufonis), and 5 species of nematodes (A plectana incerta, A. itzocanensis; Rhabdias americanus, Physaloptera s p., 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 par ent species.
