Antibodies prevalence against Toxoplasma gondii in dogs assisted at the Veterinary Hospital of the State University of Londrina (Paraná, Brazil)

Abstract

In the period from to 1935 to 1990 a serological survey of Toxoplasma gondii infection in 254 dogs with clinic signs of toxoplasmosis, was conducted using indirect immunofluorescence technique. The percentages of positive sera were 75,98% with titles ranging from 16 to 65536. The prevalence in relation to age was: up to 1 year, 67,02%; 1 to 7 years, 80,45%; over 7 years, 35,18%. These results showed that the infection has been disseminated in our environment, but in an underestimated way when evaluated only by clinic surveys.
