Abstract

Of 150 specimens of the gastropod snail Limicolaria aurora examined from the Edo and Delta states of Nigeria, 63.4% were infected with larval digeneans comprising mother sporocysts (12.1%) daughter sporocysts (20.4%) cercariae (43.1%) and metacercariae (24.5%). Attempts to experimentally infect three 14-day-old chicks (Gallus domesticus) and two laboratory-bred 4-month-old mice (Mus musculus) by oral feeding and peritoneal injection with cercariae were negative, although experimental infections of chicks via a cloacal drop yielded 62 immature and 37 mature worms from the intestinal caeca and ileum. The worms were identified as Brachylaima fuscatum (Trematoda: Brachylaimidae). The study also revealed that L. aurora acts as an intermediate host for B. fuscatum, in addition to Eulota sp., Helix sp., Helicella sp., Oxychilus sp. and Agrolimax sp.
