Cestodes des amphibiens de la province du Ganzourgou, Burkina Faso.

Abstract

The examination of amphibians, from Zam, Mogtédo and Zorgho and belonging to 5 families of amphibians (Bufonidae, Dicroglossidae, Pipidae, Ptychadenidae and Ranidae) for the research for Cestodes was carried out during the period from August 2018 to January 2019. This work aimed to inventory the amphibians’ Cestodes of Ganzourgou as well as to define their degree of infestation.

The collection method used was the visual and acoustic approach. After each collection, the amphibians have been euthanized and dissected to examine the digestive tract and general cavity for research of Cestodes. A total of 15 individuals of Cestode divided into 4 species have been collected from the 233 specimens collected amphibians. The Cestodes collected belong to 2 genera namely the genus of Cephalochlamys and Proteocephalus.

The recorded global prevalence (2, 14%) shows a very low parasitic infestation of amphibians by cestodes in the 3 sites. It appears that of the 9 amphibian species examined, only 2 species were infested by parasitic Cestodes i.e Xenopus fischbergi Evans et al., and Sclerophrys regularis Reuss, 1833. The small intestine is only site of Cestodes infestations in their host. These results could be used for large-scale studies to define the impact of parasites on the growth of amphibians.
