Prevalence of trematode in wild fish from fishing in Ho Chi Minh City

Abstract

A research on the prevalence of fishborne zoonotic trematodes (FZT), metacercariae stage, in wild fish from fishing in Nhieu Loc – Thi Nghe, Tau Hu – Ben Nghe and Thay Cai – An Ha canals was conducted in Ho Chi Minh City in the period of May 2017 and April 2018. The results showed that no metacercariae were found in fish in Nhieu Loc – Thi Nghe and Tau Hu – Ben Nghe canals. However, wild fish in Thay Cai – An Ha canal were infected with Haplorchis pumilio and Centrocestus formosanus. Metacecariae were infected in silver barb (80%), climbing perch (11.7%), snakehead (7.5%), and walking catfish (1.7%). The FZT prevalence in the wet season is significantly higher than in the dry season (P<0.05).
