ABSTRACT
Fifty-two (52) specimens consisting of four families and thirteen species of anuran were captured and examined from an altered rainforest environment, Rubber Research Institute of Nigeria, Iyanomo, Edo state from June to September 2019. The species captured were Arthroleptis poecoloenotos (1), Arthroleptis sp 1 (2), Leptopelis spiritusnoctis (6), Hoplobatrachus occipitalis (6), Afrixalus dorsalis (9), Hyperolius concolor phase A (5), Hyperolius concolor phase B (5), Hyperolius concolor phase C (7), three (3), Hyperolius fusceventris (3), Hyperolius sp 1 (4), Hyperolius sp 2 (2), Hyperolius sp 3 (1) and Chiromantis rufescens (3). The nematodes recovered were Aplectana macintohii, Camallanus dimitrovi, Camallanus sp, Chabaudus leberrei, Cosmocerca ornate, Foleyellides sp. and Physaloptera sp. The predilection sites of the nematodes recovered were oesophagus/stomach, small intestine, large intestine/rectum, and body cavity. The overall prevalence was 25.0% was low. However appreciable values were recorded for parasite in the predilection sites. The oesophagus/stomach had the highest prevalence 50.0% followed by the body cavity, 29.4% while the large intestine/rectum and the small intestine had the prevalence values of 25.0% and 13.5%, respectively. The infection of Hyperolius sp 2 by Physaloptera sp and Camallanus sp created new host records for these parasites in Nigeria. Hyperolius concolor phase C is reported to harbor Chabaudus leberrei for the first time. The low prevalence of infection could be as a result of sampling efforts and short duration of the study.
