BACKGROUND The objective of this study was to analyze gallbladder stones for direct evidence of a relationship between Clonorchis sinensis infection and gallbladder stones formation. METHODOLOGY We investigated one hundred eighty-three gallbladder stones for the presence of Clonorchis sinensis eggs using microscopy, and analyzed their composition using Fourier transform infrared spectroscopy....

The natural infection of Clonorchis sinensis has been noted widely among carnivorous mammals such as human, dog, cat and weasel etc. This infection is experimentally reproducible in rabbits and guinea pigs together with a number of other mammals, while there remains a great deal to be discussed as to whether a certain species of birds can be a definitive host. The infection of Clonorchis sinens...

We are reporting a case of a 43-year-old Chinese male from Hong Kong, who came to see a doctor complaining of acute onset of severe upper abdominal pain. A diagnosis of acute cholecystitis was made and an emergency cholecystectomy was carried out. On opening the common bile duct, lancet-shaped worms were seen emerging from it. About 45 adult worms were collected and sent to the Department of Pa...

Excavations at two sites dating from 2000 BC-1900 AD in southeastern areas of the Republic of Korea, revealed the remains of several structures. Examination of the contents suspected privies revealed the presence of eggs from 5 kinds of parasite: Ascaris, Trichuris, Clonorchis, and two species of unknown trematodes. Clonorchis sinensis eggs were found in a soil dating from around AD 668-935. Th...

biliary liver flukes are common parasites in some regions of the world where consumption of raw fresh-water fish is a cultural practice. clonorchis sinensis and opisthorchis species are the major biliary liver flukes associated with human disease. some of these parasites are highly associated with cholangiocarcinoma. this report describes a clinically and epidemiologically unsuspected liver flu...

INTRODUCTION The impact of foodborne trematode infections is gaining recognition worldwide. Clonorchiasis and opisthorchiasis are some of the most neglected tropical foodborne diseases that pose a significant threat to human health. Persistent or chronic infection of Clonorchis/Opisthorchis often leads to hepatobiliary diseases including cholangitis, cholelithiasis, cholecystitis, pancreatitis,...

Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28G...

In 1932, Loffler described a syndrome of self-limiting, transient pulmonary infiltrates associated with peripheral blood eosinophilia and mild pulmonary symptoms. A number of conditions are related to pulmonary eosinophilia or pulmonary infiltration with eosinophilia. Especially, parasitic infestations are often related to pulmonary eosinophilia, but only two cases associated with Clonorchis si...

The infection status of freshwater fish with digenetic trematode metacercariae was examined in water systems of Hantangang and Imjingang (River), the Republic of Korea. A total of 877 (594 from Hantangang and 283 from Imjingang) fishes were examined by the artificial digestion methods. Clonorchis sinensis metacercariae were detected in 7 (1.2%) fishes (in 3 spp.) from Hantangang in Cheorwon-gun...
