title: Observations of dye test (DT) titres to Toxoplasma in a non-breeding flock of sheep.
abstract: In this study nine sheep and one goat were tested by the Sabin Feldman dye test for the presence of antibodies to Toxoplasma spp over a period of 12 months. No significant signs of a seasonal variation in dye test titres of infected animals could be demonstrated. The possible source of infection of two sheep, exhibiting a sudden rise in antibody titre during the course of the observations is discussed.
