Larval strigeoid trematodes in anurans from southern Nigeria

Abstract

318 SummaryAnurans from locations in the rainforest, derived savannah and a monoculture plantation in Nigeria were examined for infection with strigeoid trematode larvae. Two types of metacercarial cysts were recovered. The cyst type I (rounded with fringe projections) occurred in tree frogs from the Okomu National Park, at Usen (derived savannah) and the Okomu Oil Palm Plantation (OOPP). The cyst type II was recovered from A. dorsalis and Ptychadena bibroni collected at OOPP. The cysts were ovoid in shape, devoid of projections at the fringes and were not subject to trypsin action. An unencysted metacercaria was found in A. dorsalis collected at Usen while mesocercaria of Alaria occurred in the lungs of Pty. pumilio at OOPP. The finding of Alaria mesocercaria in Pty. pumilio is of public health importance in view of the fact that many ranid frogs are consumed in Nigeria and other West African countries.

“…is therefore a new host record for the parasite. Hylarana galamensis is also a new host record for the strigeoid metacercaria previously reported in A. dorsalis by Edo-Taiwo et al (2014). According to Niewiadomska (2002), trematodes with this metacercarial type include Diplostomum, Neodiplostomum and Alaria spp., and they presumably use these frogs as intermediate hosts.…”

“…Other hosts of strigeiod trematode metacercariae in Africa include D. occipitalis and B. regularis reported byPike (1970) in the Sudan. Infected tree frogs serve as intermediate hosts of these trematodes for their trophic transfer to their definitive hostsEdo-Taiwo et al, 2014), which include birds and mammals(King et al, 2010).Nematodes were the predominant parasites among the parasites infecting the tree frogs in the cocoa plantations.
