Opisthorchis viverrini: The tegumental cytoskeleton

International Journal for Parasitology, 1995
The tegumental cytoskeleton of Opisthorchis viverrini was observed using both conventional transmission electron microscopy and Triton X-100 extraction. The cytoskeletal elements of the newly excysted juveniles, first-week and adult stages are composed of 2 components: firstly, the network of knobbed fibres designated as microtrabeculae which form the ...

Animal models for Opisthorchis viverrini infection

Parasitology Research, 2008
We investigated the utility of various animal models for the study of opisthorchiasis in humans and its common sequel of cholangiocarcinoma (CCA). Rats, mice, gerbils, and hamsters were infected with Opisthorchis viverrini metacercariae. Worms from the infected animal hosts were recovered from livers and counts made of eggs per gram of feces.

Genetics of Opisthorchis viverrini-related cholangiocarcinoma

Current Opinion in Gastroenterology, 2015
We review the genetic, epigenetic and transcriptional landscape of liver fluke (Opisthorchis viverrini, Ov)-related cholangiocarcinoma (CCA). Its distinct alterations, as compared with non-Ov-related CCA may help shed light on its underlying molecular mechanisms.Recent whole-exome and targeted sequencing not only confirmed frequent mutations in known ...

Bi-functionality of Opisthorchis viverrini aquaporins

Biochimie, 2015
Aquaporins (AQP) are essential mediators of water regulation in all living organisms and members of the major intrinsic protein (MIP) superfamily of integral membrane proteins. They are potential vehicles or targets for chemotherapy, e.g. in Trypanosoma brucei melarsoprol and pentamidine uptake is facilitated by TbAQP-2.

Characterization of the Opisthorchis viverrini genome

Journal of Helminthology, 1991
ABSTRACTThe methylations of trematode genomic DNA were analyzed using restriction enzymes and Southern blot hybridization. Restriction enzymes MspI, HpaII, HhaI were used to probe CpG methylation while MboI, Sau3A, DpnI were used for A methylation. The results revealed that Opisthorchis viverrini, Fasciola gigantica and Gigantocotyle siamensis had ...

Epidemiology of Opisthorchis viverrini Infection

2018
Opisthorchiasis in the Lower Mekong Subregion is a parasitic disease caused by the liver fluke Opisthorchis viverrini. This parasite has a well-documented distribution in Thailand, Lao PDR, Cambodia, Myanmar and Southern Vietnam. In this chapter, we describe the current knowledge of the epidemiology of O.

Specific monoclonal antibodies to Opisthorchis viverrini

International Journal for Parasitology, 1991
A Balb/c mouse was immunized with a crude soluble antigen of Opisthorchis viverrini adult worms (OVAA) over a period of 7 months. Spleen cells from the immune mouse were fused with Sp2/0 myeloma cells. Among the 264 tissue culture wells containing the fused cells, cells of 96 wells (36%) produced antibodies to the immunizing agent.

Opisthorchis viverrini and cholangiocarcinoma in Northeast Thailand

Parasitology Today, 1992
Population-based research is beginning to show clearly the devastating impact that Opisthorchis viverrini infection has on the Laos-descendent population of Northeast Thailand who love to eat uncooked meat and fish, one of which being the parasite's intermediate host: cyprinoid fish.

Specific gravity of Opisthorchis viverrini eggs

Journal of Helminthology, 1998
AbstractThe specific gravity of the eggs of the liver fluke Opisthorchis viverrini was determined using a sucrose gradient centrifugation and found to range from 1.2713 to 1.3043. The peak egg count was located at the sucrose fraction with a specific gravity of 1.2814. An attempt to float eggs in saturated sodium nitrate solution, sp.gr.

Acquired resistance to Opisthorchis viverrini in the hamster

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1982
Two groups of ten hamsters received a primary challenge of five Opisthorchis viverrini metacercariae intragastrically (Groups I and III) and a third group was left untreated (Group II). 90 days after the primary challenge Groups I and II were given a further 50 metacercariae.
