The efficacy of the 5-chloro-2-methylthio-6( 1 n a p t h y l o x y ) 1H-benzimidazole called compound alpha, formulated as boluses or suspension, was evaluated against adult Fasciola hepatica in cattle. Twenty-seven steers were infected, each with 600 metacercariae of F. hepatica. After 10 weeks of infection, the animals were divided into 3 groups of 9 animals each. Group 1 received boluses at ...

This study reports the early biochemical changes in plasma, comparative host-immune responses and parasite recovery data in Merino sheep during the first 10 weeks of infection with Fasciola gigantica and Fasciola hepatica. One group of sheep were uninfected, four groups of sheep received incremental challenge doses of F. gigantica metacercariae (50, 125, 225 and 400, respectively) and the sixth...

The liver fluke Fasciola hepatica parasitizes humans and ruminant livestock worldwide, and it is now being considered a reemerging zoonotic disease, especially in areas in which it is endemic, such as South America. This study investigates the immune response to excretory and secretory products produced by F. hepatica in a group of patients from the Peruvian Altiplano, where the disease is high...

glutathione s-transferase (gst) represents the major class of detoxification enzymes from helminth parasites such as fasciola hepatica and f. gigantica and it is a candidate for chemotherapeutic and vaccine design. therefore, gst enzyme of fasciola spp. could be a target for evaluation of drugs such as triclabendazole (c14h9cl3n2os). for this purpose, gst enzymes were purified from fasciola spp...

Human fascioliasis (HF), caused by the common liver fluke Fasciola hepatica, is an endemic infection in many parts of tropical countries. HF can also be seen in some of the non-tropical countries. This report describes two girls with severe iron deficiency anemia and eosinophilia, who were diagnosed as HF. The infection was successfully eliminated with the administration of triclabendazole. No ...

BACKGROUND In the present study, the detection of anthelmintic resistance to triclabendazole (TCBZ) in sheep infected by Fasciola hepatica was studied using an egg hatch assay (EHA). F. hepatica eggs were recovered from bile and faeces of infected animals by isolates with different grade of anthelmintic resistance to TCBZ: i) a resistant isolate (RT); ii) a susceptible isolate (ST); iii) natura...

An adaptation of a previously developed climate forecast computer model and digital agroecologic database resources available from FAO for developing countries were used to develop a geographic information system risk assessment model for fasciolosis in East Africa, a region where both F. hepatica and F. gigantica occur as a cause of major economic losses in livestock. Regional F. hepatica and ...

BACKGROUND Fasciolosis, caused by the liver flukes of the genus Fasciola, is one of the most prevalent diseases of domestic livestock and human throughout the world, imposing considerable economic losses. The present study was aimed to assess the effects of different pH values on hatching rate of Fasciola miracidia. METHODS The flukes were isolated from the infected livers of the slaughtered ...

A harmonized sampling approach in combination with spatial modelling is required to update current knowledge of fasciolosis in dairy cattle in Europe. Within the scope of the EU project GLOWORM, samples from 3,359 randomly selected farms in 849 municipalities in Belgium, Germany, Ireland, Poland and Sweden were collected and their infection status assessed using an indirect bulk tank milk (BTM)...
