The objective of this study was to investigate the risk factors for and prevalence of clonorchiasis in Miaoli County, Taiwan. In 2009, 6,929 subjects were randomly selected in Miaoli County and given a questionnaire to fill out regarding risk factors for clonorchiasis; the response rate was 69%. Stool sample was obtained from each participant who filled out the questionnaire and examined using ...
In many countries of South-East Asia infection with the liver fluke Opisthorchis viverrini (OV) is of considerable importance as a risk factor for cholangiocellular carcinoma (CC) development (Haswell-Elkins et al., 1994; Sriamporn et al., 2004; Sripa et al., 2011). In Viet Nam, Clonorchis sinensis may also be found (Doanh and Nawa, 2016). Infection with liver flukes (Opisthorchis viverrini, Op...
Clonorchis sinensis, an ancient parasite that infects a number of piscivorous mammals, attracts significant public health interest due to zoonotic exposure risks in Asia. The available studies are insufficient to reflect the prevalence, geographic distribution, and intraspecific genetic diversity of C. sinensis in endemic areas. Here, a multilocus analysis based on eight genes (ITS1, act, tub, ...
BACKGROUND Clonorchis sinensis (C. sinensis) is considered to be an important parasitic zoonosis because it infects approximately 35 million people, while approximately 15 million were distributed in China. Hepatitis B virus (HBV) infection is a major public health issue. Two types of pathogens have the potential to cause human liver disease and eventually hepatocellular carcinoma. Concurrent i...
Clonorchis sinensis habitating in the bile duct of mammals causes clonorchiasis endemic in East Asian countries. Parkin is a RING-between-RING protein and has E3-ubiquitin ligase activity catalyzing ubiquitination and degradation of substrate proteins. A cDNA clone of C. sinensis was predicted to encode a polypeptide homologous to parkin (CsParkin) including 5 domains (Ubl, RING0, RING1, IBR, a...
Clonorchis sinensis and Opisthorchis viverrini are both important fish-borne pathogens, causing serious public health problem in Asia. The present study developed an assay integrating real-time PCR and high resolution melting (HRM) analysis for the specific detection and rapid identification of C. sinensis and O. viverrini. Primers targeting COX1 gene were highly specific for these liver flukes...
The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed b...
Clonorchiasis, caused by the liver fluke Clonorchis sinensis, is a chronic parasitic infection regulated by T cell subsets. An imbalance of CD4+CD25+ Foxp3+regulatory T (Treg) and interleukin (IL)-17-secreting T cells (Th17) may control inflammation and play an important role in the pathogenesis of immune evasion. In the present study, we assessed the dynamics of Treg/Th17 and determined whethe...
Clonorchis sinensis is still a common parasite in South Korea. An enzyme-linked immunosorbent assay (ELISA) was developed to replace the usual intradermal test, and its performance in an area of endemicity was evaluated. From 2004 to 2006, 182 adults were included. The patient group consisted of 51 adults; 43 patients showed fluke eggs by microscopy, and 8 had their disease diagnosed clinically...
OBJECTIVES The prevalence of Clonorchis sinensis infection was investigated among residents of the five major river basins, that is, Hangang, Nakdonggang, Seomjingang, Yeongsangang, and Geumgang River basins in Korea. METHODS From January to December 2007, a total of 31,268 stool samples were collected from 29 localities and examined by the formalin-ether sedimentation technique. RESULTS In...
