Research into the species of anurans and their associated helminth parasites is essential for conservation and scientific purposes. Two reports on the helminth parasites of anurans from Ahoada area of Rivers State, Nigeria, have been documented. This research, therefore examines anurans from unexplored locations in Ahoada (namely, Ahoada Main Town and Joinkrama). Search and capture techniques were employed in sampling and standard parasitological methods were used. Helminth parasites were fixed in appropriate fixatives. Both anuran and parasitic species were identified using applicable keys. Prevalence and mean intensity of infection were computed following conventional methods. Twenty-eight anuran species comprised of Hoplobatrachus occipitalis, Ptychadena bibroni, P. oxyrhynchus, P. pumilio, P. mascareniensis and Hymenochirus sp. were collected from Ahoada Main Town. These were infected with fourteen helminth parasite species (namely monogeneans [Polystoma aeschlimanni and P. pricei], digeneans [Mesocoelium monodi, Diplodiscus fischthalicus, Ganeo africana and Metahaematoloechus exoterorchis], cestodes [Cylindrotaenia jaegerskioeldii], and nematodes [encysted ascaridida larvae, Rhabdias sp., Oswaldocruzia hoepplii, Cosmocerca ornata, Chabaudus leberrei and Amplicaecum africanum]. At Joinkrama, thirty amphibian specimens comprised of toads (Sclerophrys maculata) and frogs (Hylarana galamensis, Hoplobatrachus occipitalis, Ptychadena bibroni and Ptychadena mascareniensis) were examined. Ten helminth species (namely, acanthocephalan cystacanths, cestodes (Cylindrotaenia jaegerskioeldii), trematodes (Diplodiscus fischthalicus, Mesocoelium monodi, Metahaematoloechus exoterorchis) and nematodes (Amplicaecum africanum, Cosmocerca ornata, Rhabdias sp., Rhabdias africanus and Oswaldocruzia hoepplii) were isolated from infected hosts. Prevalence of infection ranged from 6.25% to 100% at both locations; mean intensity ranged from one to twenty-one parasites per infected hosts at Ahoada Main Town and one to thirteen at Joinkrama. The altered nature of the habitats surveyed is thought to have influenced both the anuran and endohelminth parasites diversity recorded. |
