| Popis: | 106 Eating raw or undercooked fishes may acquire various fish-borne parasites which may cause human and animal to suffer from zoonotic parasitosis that can be emerged or re-emerged due to intensive population movements and climatic change. In the present study, we intended to investigate the infection status of fish-borne zoonotic trematodes (FZT) from freshwater fishes which were collected from Beixi River, Pinglin District, New Taipei City and Meizi Liu River, Xindian District, respectively, New Taipei City by detection of the metacercaria using morphological characteristics and PCR identification. The gills, caudal fins, viscera and scales of each fish were examined to detect any metacercaria. Totally, we have collected 90 freshwater fishes with five different species, namely Zacco platypus (n= 8), Opsariichthys pachycephalus (n= 23), Candidia barbata (n= 28), Acrossocheilus paradoxus (n= 16) and Varicorhinus barbatulus (n= 15), respectively. Results indicated that the overall prevalence of FZT metacercaria is 53.3% (48/90), of which the prevalence in fishes caught from Beixi River (92%, 46/50) was significantly higher than that seen in fishes caught from Meizi Liu River (5%, 2/40) (p < 0.05). According to fishes species, the highest prevalence was found in Zacco platypus (87.5%, 7/8) then Opsariichthys pachycephalus (60.9%, 14/23), following by Candidia barbata (57.1%, 16/28), Acrossocheilus paradoxus (56.3%, 9/16) and the lowest was Varicorhinus barbatulus (13.3%, 2/15), respectively. No significant difference in prevalence and infection intensity of metacercaria in scales in different sites of fishes (p > 0.05). Meanwhile, we also found Acanthocephala and unknown parasites which needs further identification. |
