There is only one survey on the species of amphibians and their parasites from Okrika,
Rivers State, Nigeria. Therefore, this research was carried out with the intention of
exploring the city for more amphibian species and also reporting on the parasites infecting
them. Visual acoustic and survey methods were employed in surveying the study location,
Greame Ama, for the period of September to November, 2018, and standard
parasitological techniques were adopted. In comparison with the earlier research, fewer
amphibian species were encountered: Sclerophrys maculata, Hoplobatrachus occipitalis,
Ptychadena pumilio and P. mascareniensis. However, new parasite species were found:
Diplodiscus fischthalicus, Metahaematoloechus exoterorchis and Cephalochlamys
compactus. A higher prevalence of infection (96.6%) was reported here than in the earlier
report. Of the nine parasite species reported in this research, three have direct transmission
routes (Rhabdias sp., Cosmocerca ornata, Cylindrotaenia jaegerskioeldii), while six
(Raillietiella sp., Cephalochlamys compactus, Mesocoelium monodi, D. fischthalicus,
Metahaematoloechus exoterorchis and ascaridida larva) are transmitted by ingestion of
either insect or gastropod intermediate hosts. However, the most prevalent species were
those with direct transmission routes as is common with more terrestrial amphibian
species. It is concluded that amphibian diversity in Okrika is low but more parasite species
are likely to be reported with more surveys.
