Occurrence of Tetracampos ciliotheca (Cestoda: Bothriocephalidea) in the gall bladder of Clarias anguillaris in Burkina Faso

Abstract

The presence of the bothriocephalidean cestode Tetracampos ciliotheca Wedl, 1861 is reported from the gall bladders of the catfish Clarias anguillaris from Loumbila and Ziga reservoirs, Burkina Faso, in 2010–2011. Of the 159 specimens examined, 47 were infected. Mean intensity of infection was 4.3 parasites per infected host, the maximum was 22 tapeworms in the gall bladder and the mean abundance was 1.3 parasites. There was no significant difference between males and females or between the two localities. There was a positive relationship between fish size and the number of parasites in the gall bladder. This study provides further evidence of the presence of T. ciliotheca in the gall bladder, in which most tapeworms found were localised. Tapeworms were also found in the stomach and intestine, with prevalences of 1% and 16%, and mean infection intensities of 1 and 5.3, respectively.
