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 fir...

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 and Pedro Leopoldo, were examined.
