| aspects of the maintenance of the life cycle of fasciola hepatica in lymnaea columella in minas gerais, brazil. | fascioliasis is a parasitic disease of domestic ruminants that occurs worldwide. the lymnaeid intermediate hosts of fasciola hepatica include lymnaea columella, which is widely distributed in brazil. a colony of l. columella from belo horizonte, mg, was reared in our laboratory to be used in studies of the f. hepatica life cycle, the intermediate host-parasite relationship and development of an anti-helminthic vaccine. in the first experiment 1,180 snails were exposed to miracidia of f. hepatica ... | 2002 | 12048573 |
| occurrence of fasciola hepatica (linnaeus, 1758) infection in brazilian cattle of minas gerais, brazil. | fasciolosis is a parasitic disease which is caused by digenetic trematodes, such as fasciola hepatica, and which occurs worldwide. the disease causes significant economic losses in cattle because of the reduction in milk and meat production and because the parasitized livers have no economic value. also, abortion and mortality rates increase. to determine the occurrence and dispersal of f. hepatica in the state of minas gerais, fecal samples were collected from bovines aged 12 months and older b ... | 2009 | 19602313 |
| fasciola hepatica in bovines in brazil: data availability and spatial distribution. | fasciolosis is a disease of importance for both veterinary and public health. for the first time, georeferenced prevalence data of fasciola hepatica in bovines were collected and mapped for the brazilian territory and data availability was discussed. bovine fasciolosis in brazil is monitored on a federal, state and municipal level, and to improve monitoring it is essential to combine the data collected on these three levels into one dataset. data were collected for 1032 municipalities where live ... | 2017 | 24553606 |
| autochthonous infection of buffaloes and cattle by fasciola hepatica in minas gerais, brazil. | fasciola hepatica is a digenetic trematode that parasitizes the bile ducts of different species of vertebrate hosts. in brazil, this parasitosis is expanding and occurrences have been reported in the southern, southeastern, central-western and northeastern regions. this study aimed to report the first case of naturally infection of buffaloes by this parasite in the state of minas gerais. a total of 250 stool samples, 176 from cattle and 74 from buffaloes, from the districts of são josé da lapa a ... | 2016 | 25271466 |
| occurrence of fasciola hepatica (linnaeus, 1758) in capybara (hydrochoerus hydrochaeris) (linnaeus, 1766) in minas gerais, brazil. | fasciola hepatica is a parasite that affects the hepatic ducts of several species of domestic and wild vertebrates, causing huge economic losses to livestock rearing worldwide. reports on occurrences of f. hepatica in capybaras are an important epidemiological aspect of this disease, since these rodents can be a source of contamination for other animals and humans. in the present study, conducted in a rural area of the municipality of confins, minas gerais, fresh feces from capybaras were collec ... | 2016 | 27096531 |
| population dynamics of lymnaea columella and its natural infection by fasciola hepatica in the state of minas gerais, brazil. | studies on the population dynamics and natural infection of lymnaea columella by fasciola hepatica were carried out from september 1999 to december 2000 in a low-lying area near itajubá in the brazilian state of minas gerais. a total of 626 snails were collected monthly at nine different sites, counted, and dissected to search for larvae of f. hepatica. the highest populations of l. columella were reached in october of 1999 and august of 2000, and the highest natural infection rates of snails by ... | 2003 | 12590657 |
