After collecting 289 specimens, all belonging to the Anuran order and Bufonidae family, three species were identified: Sclerophrys camerunensis (Parker, 1936), Sclerophrys regularis (Reuss, 1834) and Sclerophrys sp. The most abundant species were Sclerophrys camerunensis, followed by Sclerophrys regularis. With regard to parasitological aspects, of the 289 specimens collected, 195 were parasitized, i.e. a percentage of 67.47%. The only parasitic species identified was Ascaris sp., which is preferentially located in the intestine.展开更多

The objective of this study was to evaluate the water management modalities in the two villages with ethnic differences and possibly detect factors that could cause waterborne diseases. A questionnaire on water management methods was submitted to one hundred one women drawn in the villages of Dielmo and Ndiop. Samples of well water and water stored in canaries were subjected to both parasitological and bacteriological analysis. In both villages, there was a difference in water management with respect to household configuration (monogamous, polygamous). The containers used for the drawing and storage of water were the same in their two villages. No helminth eggs were found in the drinking water, but bacterial germs, especially faecal coliforms (an indicator of human contamination) and Enterocoques (an indicator of animal contamination). These waters do not comply with WHO standards. So it is important to disinfect them before consumption although no cases of gastroenteritis have been reported.展开更多
