Faecal examinations for helminth eggs were performed on 1869 people from two riverside localities, Vientiane Municipality and Saravane Province, along the Mekong River, Laos. To obtain adult flukes, 42 people positive for small trematode eggs (Opisthorchis viverrini, heterophyid, or lecithodendriid eggs) were treated with a 20-30 mg kg(-1) single dose of praziquantel and purged. Diarrhoeic stoo...

Thequestionnaire was divided into four subsectionsdealing with pre-calving (breeding, diet and bodycondition score, endemic infectious diseases) andcalving factors . Most of the...
This review summarises the findings of a series of studies in which the histological changes, induced in the reproductive system of Fasciola hepatica following treatment of the ovine host with the anthelmintic triclabendazole (TCBZ), were examined. A detailed description of the normal macroscopic arrangement and histological features of the testes, ovary, vitelline tissue, Mehlis' gland and ute...
In Hokkaido, Japan, wild sika deer are highly infected with Fasciola flukes, suggesting that the flukes complete their life cycle via intermediate host snails and definitive host animals occurring in the natural environment. However, infected snails have been found only in cattle farms contaminated with fasciolosis. This study reports the first Fasciola larva infection in Galba truncatula snail...
Recent studies show that parasites such as liver flukes have a capacity to bioaccumulate heavy metals significantly than the liver and muscle tissues of the host without compromising effects on them. One such heavy metal is lead (Pb) which is an abundant pollutant in the environment. Therefore, this study aimed to evaluate the effects of lead in the tegument of Fasciola gigantica (giant liver f...
