Abstract

An inventory of digestive parasites of the edible frog Hoplobatrachus occipitalis was carried out in Benin. A total of 135 specimens were caught in the River basins of the Mono, Ouémé and Niger and examined in the laboratory. Results show that 78.52% of the specimens had at least one egg per gram of faeces. The percentages of infested individuals are 91.1%, 77.7% and 66.7%, respectively for the Mono, Ouémé and Niger River basins. Nematodes (Oxyuris sp., Œsophagostomum sp. and Heterakis sp.) and coccidia (Eimeria sp.) were identified. The frequencies of singular or cross-infestations of subjects are as follows: Eimeria sp. (25.93%), Eimeria sp. and Oxyuris sp. (25.2%), Oxyuris sp. (20.0%), Eimeria sp. and Heterakis sp. (2.96%), Eimeria sp. and Œsophagostomum sp. (2.22%), Œsophagostomum sp. (1.48%) and Heterakis sp. and Oxyuris sp. (0.74%). An infestation rate of 20.7% of frogs moderately infested against 54.8% heavily infested is obtained with a level of infestation varying significantly from one basin to another. The infestation rates are 80.4%, 68.9% and 86.4% in the colon, small intestine and both organs taken together. The proportion of infested adults (87.5%) was significantly higher than that of juveniles (61.7%).
