Distribution of bovine fasciolosis and associated factors in south Espírito Santo, Brazil: an update
The geographical distribution and factors associated with bovine fasciolosis in the south of Espírito Santo were updated and the prevalences of this disease and of snails of the genus Lymnaea in the municipality of Jerônimo Monteiro were calculated. In the first stage, fecal samples were collected f...

The geographical distribution and factors associated with bovine fasciolosis in the south of Espírito Santo were updated and the prevalences of this disease and of snails of the genus Lymnaea in the municipality of Jerônimo Monteiro were calculated. In the first stage, fecal samples were collected from 10% of the herds of 115 farms in 23 municipalities and interviews were conducted with owners. Generalized linear mixed models were used. In the second stage, in Jerônimo Monteiro municipality, feces and mollusks were collected from all farms registered in the milk cooperatives in the region. The mollusks were identified and examined for infection by Fasciola hepatica. Fasciolosis was diagnosed in 18 (78%) of the 23 municipalities. Of the 1157 fecal samples examined, 19.01% were positive for eggs of F. hepatica. The final model shows statistical evidence of associations between positive farms and previous cases of fasciolosis and concomitant grazing of cattle with other definitive hosts.

The wide geographical distribution of bovine fasciolosis in the south of Espírito Santo requires control measures to prevent its expansion towards the north of this state and other places characterized as F. hepatica free-infection. |
