Twenty provinces in northeastern Thailand were investigated for fluke metacercariae contamination in pickled fish, or pla-som, during January –June 2016. A total of 129 pickled fish shops were randomly chosen. Samples were digested with acid-pepsin and those found to be infected with metacercariae were fed to hamsters to test for metacercariae infectivity. The results demonstrated that only 20....
OBJECTIVES To isolate and characterize an asparaginyl endopeptidase from the carcinogenic liver fluke, Opisthorchis viverrini, and evaluate its expression profile, biochemical activity, and potential as an immunodiagnostic antigen. METHODS The full length mRNA encoding an asparaginyl endopeptidase (family C13), Ov-aep-1, was isolated by immunoscreening of a cDNA bacteriophage library of adult...
The nitric oxide (NO) formation and intrinsic nitrosation may be involved in the possible mechanisms of liver fluke-associated carcinogenesis. We still do not know much about the responses of inducible NO synthase (iNOS) induced by Clonorchis sinensis infection. This study was conducted to explore the pathological lesions and iNOS expressions in the liver of mice with different infection intens...
Infection with the liver fluke, Opisthorchis viverrini, is a causative agent of cholangiocarcinoma. One possible contributing factor in this carcinogenesis is the chronic, local generation of nitric oxide by inflammatory cells expressing inducible nitric oxide synthase and the production of N-nitroso compounds via the reaction between amines and nitrosating agents derived from nitric oxide. Our...
Infection with Dicrocoelium dendriticum in humans is seldom to be reported in Egypt. This liver fluke, which commonly infects ruminants, has a complex life cycle with two intermediate hosts; the land snail and the ant. Human infection occurs by accidental ingestion of the second intermediate host. The present reported a patient suffered from recurrent acute chole-cystitis with chronic urinary s...
D icrocoelium dendriticum is the most widespread liver fluke in cattle and sheep in Italy [1]. Adult forms live in the gall bladder and bile ducts of their final hosts (ruminants). Eggs are passed in faeces and ingested by land snails which excrete cercaria in mucous balls, which are eaten by ants. Infestation usually occurs by ingestion of ants that carry metacercariae by animals and occasiona...
