Abstract

Adult notocotylid flukes (Digenea: Notocotylidae) were recovered from the ceca of Pitalah ducks (Anas sp.) in Aceh Province, Indonesia. These flukes were morphologically characterized by a median ventral ridge with 2 lateral rows of ventral papillae and the absence of both a ventral sucker and pharynx, consistent with the characteristics of the genus Catatropis. They exhibited a genital pore located just posterior to the oral sucker, 10–11 pairs of ventral papillae, a deep and multi-lobed ovary and testes, a metraterm equal in length to the cirrus sac, and ceca bearing numerous diverticula; accordingly, they were identified as Catatropis indicus Srivastava, 1935. Adult specimens measured 3.01–3.77 mm (average 3.47 mm) in length and 0.98–1.21 mm (average 1.11 mm) in width (n=8). Uterine eggs measured 0.016–0.023 mm (average 0.019 mm) in length and 0.008–0.014 mm (average 0.012 mm) in width (n=20), each bearing 2 long polar filaments. These specimens resembled Catatropis vietnamensis Izrailskaia et al., 2019, and Catatropis pakistanensis Schuster and Wibbelt, 2012, sharing features such as a genital pore immediately posterior to the oral sucker and other morphological traits. However, they differed from C. vietnamensis by having a larger body, ceca with numerous diverticula, and a broader anterior distribution of vitelline follicles. They also differed from C. pakistanensis in possessing a longer esophagus and ceca with multiple diverticula. In 28S rDNA sequence analysis, our specimens showed 99.1% identity with both C. indicus and C. vietnamensis. In contrast, internal transcribed spacer 2 (ITS2) sequence comparisons revealed only 96.0%–96.1% identity with C. vietnamensis (no GenBank data available for C. indicus), suggesting that our specimens are phylogenetically distant from C. vietnamensis. This represents the first report of C. indicus from ducks in Indonesia. A brief review of Catatropis species is provided.

Echinostoma miyagawai Ishii, 1932 (Echinostomatidae) from Ducks in Aceh Province, Indonesia with Special Reference to Its Synonymy with Echinostoma robustum Yamaguti, 1935: Jong-Yil Chai, Bong-Kwang Jung, Taehee Chang, Hyejoo Shin, Jaeeun Cho, Jin-Youp Ryu, Hyun-Seung Kim, Kwanghoon Park, Mun-Hyoo Jeong, Eui-Hyug Hoang, Marzuki Bin Muhammad Abdullah; Korean J Parasitol 2021;59(1):35-45.

Abstract
PDF

Adult echinostomes having 37 collar spines collected from the intestine of Pitalah ducks in Aceh Province, Indonesia in 2018 were morphologically and molecularly determined to be Echinostoma miyagawai Ishii, 1932 (Digenea: Echinostomatidae). Among 20 ducks examined, 7 (35.0%) were found to be infected with this echinostome, and the number of flukes collected was 48 in total with average 6.9 (1-17) worms per duck. The adult flukes were 7.2 (6.1-8.5) mm in length and 1.2 (1.0-1.4) mm in width (pre-ovarian or testicular level) and characterized by having a head collar armed with 37 collar spines (dorsal spines arranged in 2 alternating rows), including 5 end group spines, and variable morphology of the testes, irregularly or deeply lobed (3-5 lobes) at times with horizontal extension. The eggs within the worm uterus were 93 (79-105) ?m long and 62 (56-70) ?m wide. These morphological features were consistent with both E. miyagawai and Echinostoma robustum, for which synonymy to each other has been raised. Sequencing of 2 mitochondrial genes, cox1 and nad1, revealed high homology with E. miyagawai (98.6-100% for cox1 and 99.0-99.8% for nad1) and also with E. robustum (99.3-99.8% for nad1) deposited in GenBank. We accepted the synonymy between the 2 species and diagnosed our flukes as E. miyagawai (syn. E. robustum) with redescription of its morphology. Further studies are required to determine the biological characteristics of E. miyagawai in Aceh Province, Indonesia, including the intermediate host and larval stage information.

Prevalence of Opisthorchis viverrini-Like Fluke Infection in Ducks in Binh Dinh Province, Central Vietnam: Thanh Thi Ha Dao, Emmanuel Nji Abatih, Thanh Thi Giang Nguyen, Ha Thi Lam Tran, Sarah Gabri?l, Suzanne Smit, Phap Ngoc Le, Pierre Dorny; Korean J Parasitol 2016;54(3):357-361.

Abstract
PDF

Following the first report of Opisthorchis viverrini infection in a domestic duck in Phu My District of Binh Dinh Province, Central Vietnam, many other cases were observed in the province. We determined the infection rate and intensity of O. viverrini infection in ducks in 4 districts of the province. A total of 178 ducks were randomly selected from 34 farms for examination of flukes in the liver and gall bladder. An infection rate of 34.3% (range 20.7-40.4% among districts) was found; the intensity of infection was 13.8 worms per infected duck (range 1-100). These findings show the role of ducks as a host for O. viverrini, duck genotype, which is sympatric with the human O. viverrini genotype in this province. It also stresses the need for investigations on the zoonotic potential and the life cycle of this parasite.

Zoonotic Echinostome Infections in Free-Grazing Ducks in Thailand: Weerachai Saijuntha, Kunyarat Duenngai, Chairat Tantrawatpan; Korean J Parasitol 2013;51(6):663-667.
Published online December 31, 2013; DOI: https://doi.org/10.3347/kjp.2013.51.6.663

Abstract
PDF

Free-grazing ducks play a major role in the rural economy of Eastern Asia in the form of egg and meat production. In Thailand, the geographical location, tropical climate conditions and wetland areas of the country are suitable for their husbandry. These environmental factors also favor growth, multiplication, development, survival, and spread of duck parasites. In this study, a total of 90 free-grazing ducks from northern, central, and northeastern regions of Thailand were examined for intestinal helminth parasites, with special emphasis on zoonotic echinostomes. Of these, 51 (56.7%) were infected by one or more species of zoonotic echinostomes, Echinostoma revolutum, Echinoparyphium recurvatum, and Hypoderaeum conoideum. Echinostomes found were identified using morphological criteria when possible. ITS2 sequences were used to identify juvenile and incomplete worms. The prevalence of infection was relatively high in each region, namely, north, central, and northeast region was 63.2%, 54.5%, and 55.3%, respectively. The intensity of infection ranged up to 49 worms/infected duck. Free-grazing ducks clearly play an important role in the life cycle maintenance, spread, and transmission of these medically important echinostomes in Thailand.
