Neospora caninum antibodies in dairy cattle of Lages Municipality, Santa Catarina State, Brazil

Bovines are the main intermediary host of the protozoan Neospora caninum, which is a major cause of bovine abortions and neonatal mortality worldwide. Sera were collected from 373 dairy cattle and 33 dogs on 19 dairy farms in Lages city, Santa Catarina State, Brazil, to determine the prevalence of N...

Sera were collected from 373 dairy cattle and 33 dogs on 19 dairy farms in Lages city, Santa Catarina State, Brazil, to determine the prevalence of N. caninum antibodies and risk factors. Tests for N. caninum antibodies were done using an indirect immunofluorescent antibody test (IFAT). Positive reactions with titers ≥ 1:200 (cattle) and ≥ 1:50 (dogs) were found in 86 (23.1%) and seven (21.2%) bovines and dogs, respectively.
