Nematodes of the Rhinella granulosa Spix, 1824 (Anura: Bufonidae) from the Semiarid Northeastern Caatinga Region of Brazil

We examined 31 specimens of Rhinella granulosa from the semiarid Caatinga region of northeastern Brazil for the presence of gastrointestinal nematodes. We found 7 nematode taxa: Rhabdias androgyna, Raillietnema spectans, Aplectana membranosa, Oswaldocruzia sp., Physaloptera sp., Raillietnema sp., and cosmocercidae larvae. The total prevalence was 25.8% and by mean intensity of infection (+/- SD) was 50 +/- 7.36. The prevalence in males was 10% with an intensity of 4 while in females it was 42.85% with a mean intensity of 42 +/- 8.55. The juveniles presented a prevalence of 14.28% and an intensity of 4. Rhinella granulosa represents a new host for the following nematodes: Rhabdias androgyna, Raillietnema spectans, and Raillietnema sp.
