genomes of fasciola hepatica from the americas reveal colonization with neorickettsia endobacteria related to the agents of potomac horse and human sennetsu fevers.food borne trematodes (fbts) are an assemblage of platyhelminth parasites transmitted through the food chain, four of which are recognized as neglected tropical diseases (ntds). fascioliasis stands out among the other ntds due to its broad and significant impact on both human and animal health, as fasciola sp., are also considered major pathogens of domesticated ruminants. here we present a reference genome sequence of the common liver fluke, fasciola hepatica isolated from sheep, complementing ...201728060841
further trials with hexachloroethane as a treatment for liver fluke in oregon cattle. 194620290850
multiple origins of european populations of the giant liver fluke fascioloides magna (trematoda: fasciolidae), a liver parasite of ruminants.the giant liver fluke, fascioloides magna, a liver parasite of free-living and domestic ruminants of europe and north america, was analysed in order to determine the origin of european populations and to reveal the biogeography of this originally north american parasite on the european continent. the variable fragments of the mitochondrial cytochrome c oxidase subunit i (cox1; 384bp) and nicotinamide dehydrogenase subunit i (nad1; 405bp) were used. phylogenetic trees and haplotype networks were ...201021172350
dna-based identification of a hepatic trematode in an elk calf.liver fluke infection was identified as a probable cause of clinical disease in an approximately 6-mo-old elk (cervus elaphus) in coastal oregon. clinical pathology and necropsy findings are described. the alcohol-fixed flukes that were submitted for identification were similar in size to fasciola hepatica, but their shape resembled fascioloides magna in that they lacked a distinctive anterior cone. a few structures consistent with the eggs of f. magna were observed in liver lesions, suggesting ...200717984277
influence of ivermectin and clorsulon treatment on productivity of a cow-calf herd on the southern oregon coast.the reproductive performance of beef cows and the weight gain of their calves was evaluated after oral administration of clorsulon or clorsulon in combination with the subcutaneous administration of ivermectin. one hundred and fifty pregnant cows harboring infections of fasciola hepatica were assigned to one of three treatment groups: group 1 comprising 50 unmedicated controls; group 2, 50 cows treated with clorsulon orally at 7 mg kg-1; group 3, 50 cows treated with clorsulon orally at 7 mg kg- ...19921561761
development and application of a dot-elisa test for the detection of serum antibodies to fasciola hepatica antigens in llamas.a microenzyme-linked immunosorbent assay (dot-elisa) was developed to detect serum antibodies against fasciola hepatica antigens in llamas. sera from five f. hepatica-infected and 11 non-infected llamas were used in initial test development. nitrocellulose filter disks containing f. hepatica excretory-secretory product were placed in 96-well microtiter plates, washed, blocked with tween-20, then incubated with four-fold serial dilutions of llama sera. after incubation with rabbit anti-llama igg ...19957676604
fasciola hepatica: comparison of flukes from korea and the united states by isoelectric focusing banding patterns of whole-body protein.comparisons were made between the flukes from chonnam, korea and oregon, usa by isoelectric focusing (ief) of whole-body protein. adult fasciola hepatica were recovered from bile ducts of korean native cattle. whole-body protein of the flukes was subjected to ief, and the banding patterns of the fluke protein were compared with those of north american f. hepatica recovered from experimentally infected calves. the overall banding pattern of f. hepatica from korea was essentially identical to that ...19921496791
suspected infectious necrotic hepatitis (black disease) in oregon cattle.suspected infectious necrotic hepatitis (black disease) in a herd of 436 cattle in douglas county, oregon, resulted in 79 deaths during a 2-week period. although clostridium novyi could not be isolated from hepatic lesions, the clinical course of the disease, gross and histopathologic findings, and fluorescent antibody identification of c novyi in various tissues were suggestive of the disease. the epizootic was preceded by a long drought, during which grazing conditions were sparse. a few days ...1977903284
