Studies on the role of some nile fishes in transmitting some trematodes of zoonotic importance in Behera governorate

ABSTRACT

A total of 240 fish samples [Mugil cephalus, Tilapia zilli and Clarias lazera] were examined for detection of encysted metacercariae in their muscles and organs. The rate of metacercarial infestation was 82.5%, 65% and 71.25% in M. cephalus, T. zilli and Cl. lazera, respectively. The rate of metacecarial infestation in the different body parts of the examined fishes was also concerned. The study showed that T. zilli act as a 2nd intermediate host for Haplorchis pumilio, Pygidiopsis genata, Mesostephanus appendiculatus, Prohemistomum vivax and Echinochasmus perfoliatus, while Cl. lazera was a 2nd intermediate host for [H. pumilio, M. appendiculatus and P. vivax, but M. cephalus was a 2nd intermediate host for H. pumilio, P. genata, M. appendiculatus and E. perfoliatus. On the other h and, dog was the final host for all the recovered flukes
