Molecular and serological investigation of infectious diseases in captive and free-range crab-eating fox (Cerdocyon thous - Linnaeus, 1776) from northeastern Brazil.

The aim of this study was to detect DNA and antibodies anti-Leishmania spp., Neospora caninum and Toxoplasma gondii in captive and free-range crab-eating fox (Cerdocyon thous) from northeastern Brazil. Twenty-five crab-eating foxes from different states of northeastern Brazil were sampled by this study.

Incidence and vertical transmission rate of Neospora caninum in sheep.

The infection by Neospora caninum in sheep can lead to abortion and the birth of weak and debilitated lambs. The aim of this study was to assess the incidence of natural infection by Neospora caninum and the vertical transmission rate among sheep. A flock of 50 sheep was monitored for serum antibody titres against N.

Occurrence of anti-Toxoplasma gondii antibodies and parasite DNA in raw milk of sheep and goats of local breeds reared in Northeastern Brazil.

The aim of the present study was to detect Toxoplasma gondii DNA in raw milk samples of goats and sheep of local breeds from the semi-arid region of the states of Pernambuco and Paraíba, Northeastern Brazil. Serum and milk samples were collected from 243 animals (186 goats and 57 sheep). The Indirect fluorescent antibody test (IFAT) was used to search for anti-T.

Prevalence of Toxoplasma gondii in slaughtered pigs in the state of Pernambuco, Brazil.

The object of this study was to investigate Toxoplasma gondii antibodies and parasite DNA in pigs in the state of Pernambuco, Brazil. Blood samples were collected from 305 slaughtered pigs in 11 municipalities, and their sera were tested for T. gondii antibodies using the indirect fluorescent antibody test (IFAT, cutoff 1:64); 38 (12.
