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...

Knowledge of the population dynamics of parasites and their hosts is essential to build veterinary and health programs. The example chosen is that of Fasciola hepatica, a food-borne trematode responsible for severe human and animal infections on the five continents. In this paper, we review the relationships between the liver fluke and its intermediate (mollusc) and definitive (vertebrate) hosts.

Fasciolopsis buski is the largest intestinal fluke infecting human beings. This trematode is endemic in certain parts of the country. Migration poses the risk of spread of the worm to other parts of the country. We report fasciolopsis buski in a migrant from Bihar working in Coimbatore, Tamil Nadu. Acute kidney injury following intestinal obstruction occurred in this case which was never descri...

Swimming efficiencies of fish and cetaceans have been related to a certain synchrony between stroke cycle frequency, peak-to-peak tail/fluke amplitude and mean swimming speed. These kinematic parameters form a non-dimensional wake parameter, referred to as a Strouhal number, which for the range between 0.20 and 0.40 has been associated with enhanced swimming efficiency for fish and cetaceans. Y...

Parasitology textbooks have long reported that grapsid crabs in the genus Eriocheir, commonly known as mitten crabs, are important second intermediate hosts of the Oriental Lung Fluke, Paragonimtrs westermani, along with several other crab'and crayfish species in Asia (e.g., Hegner and others 1929; Chandler and Read 196 1 ; Muller 1975; Cheng 1986; Smyth 1994). Epidemiologic reviews have specif...

Rumen fluke (RF) are trematode parasites that have increased in prevalence within European ruminant livestock since the 1990s. Morbidity and mortality can result from development of juvenile flukes duodenum, however, evidence for significant impacts adult rumen final host is equivocal. The presence Scotland had not previously been quantified, so purpose this study was to use historical coprolog...

Fascioliasis causes significant economic losses and is a constant challenge to livestock farmers globally. Fluke faecal egg counts (flukeFECs) are simple, non-invasive method used detect the presence of patent liver fluke infection. Many flukeFEC techniques exist but they vary in complexity, precision accuracy. The objective this study was evaluate recovery capabilities two simple methods at di...
