Abstract:
A survey was performed to investigate the infection status of zoonotic helminth larvae in fish from a local market of North Dagon District in Yangon City, Myanmar. A total of 486 fish in 13 species were collected 8 times from December 2015 to December 2019. All fish were transported under ice to a laboratory in Korea and examined for helminth larvae using artificial digestion method. Larval gnathostomes and metacercariae of more than 8 zoonotic trematode species, i.e., 〈 i 〉 Opisthorchis viverrini, Haplorchis taichui, H. pumilio, H. yokogawai, Centrocestus 〈 /i 〉 spp., 〈 i 〉 Stellantchasmus falcatus, Pygidiopsis cambodiensis 〈 /i 〉 , and 〈 i 〉 Procerovum 〈 /i 〉 sp., were detected. Larval gnathostomes were found in 58 (16.0%) out of 362 fish of 6 species, with mean intensity of 2.8 per fish infected. Metacercariae of 〈 i 〉 O. viverrini 〈 /i 〉 were detected in 10 (2.9%) out of 349 fish of 5 species, with mean intensity of 16.9 per fish infected. Metacercarial prevalences of 4 intestinal flukes, 〈 i 〉 H. taichui, H. pumilio, H. yokogawai, 〈 /i 〉 and 〈 i 〉 Centrocestus 〈 /i 〉 spp., were 16.8%, 26.0%, 12.5%, and 15.0% in the positive fish species, respectively, and mean metacercarial intensity was 63.3, 26.8, 86.2, and 8.7 per fish infected. Metacercariae of 〈 i 〉 S. falcatus 〈 /i 〉 and 〈 i 〉 P. cambodiensis 〈 /i 〉 were detected only from the mullet, 〈 i 〉 Chelon macrolepis 〈 /i 〉 . Metacercariae of 〈 i 〉 Procerovum 〈 /i 〉 sp. were found in 〈 i 〉 Channa striata 〈 /i 〉 and 〈 i 〉 Anabas testudineus 〈 /i 〉 . Collectively, it was confirmed that the fish were infected with gnathostome larvae and metacercariae of 〈 i 〉 O. viverrini 〈 /i 〉 and intestinal flukes in Yangon City, Myanmar.
