Se investiga la presencia de anticuerpos anti-Leishmania mediante una técnica de «Dot-ELISA» en 1. 328 muestras de sangre procedentes de 902 perros de la comarca del Priorat (Cataluña), importante foco de leishmaniosis canina. El umbral de positividad para la mencionada técnica (11800) se establece a partir de los datos obtenidos al realizar en paralelo cultivo y serología. Los resultados serológicos obtenidos permiten observar una tasa de prevalencia de la infección de 10,2%. Tan sólo el 49,8 % de los sueros estudiados son totalmente negativos. Al 40 % restante se le detecta anticuerpos anti-Leishmania a títulos inferiores al umbral establecido cuyo posible significado se discute. * The presence of anti-Leishmania antibodies is studied in 1328 blood samples from 902 dogs from the Priorat region (Catalonia), an important focus of canine leúhmaniosú, by a Dot-ELISA technique. The cut-off (1/800)is established through the data obtained by serology and culture in parallel. The prevalence of seropositives observed was 10,2 %. Only 49,8 % of sera were completely negative. The remaining 40% had anti-Leishmania antibodies at titres below the cut- off, the possible significance of which is discused.
