title: Development of Centrocestus armatus in different final hosts.
abstract: In this study, Centrocestus armatus metacercariae were fed orally to hamsters, albino rats, mice, and chicks. Animals were sacrificed and dissected at 1, 3, 5, 7, and 14 days post-infection to determine the development and recovery rate of worms. Results indicated that the average worm recovery rate in hamsters was 25% on the first day post-infection and recovery continued until the 14th day with a gradual decrease in the percentage. Worms were also recovered from mice and albino rats from the first until the third day post-infection, but no worms were recovered thereafter. In chicks, worms were not observed on first day but recovery was positive at 12 h post-infection. Among the four animal hosts, feces from hamsters were the only ones positive for eggs; these were initially observed from the third day and recovery continued until 14 days post-infection. In our study, hamsters are the animal model most suitable for the study of C. armatus when compared to rats, mice, and chicks.
