ABSTRACT
A total of 1655 ovine sera from the six principal sheep rearing areas of Colombia were examined for toxoplasma antibodies using the indirect haemagglutination test. It was shown that 58 per cent of these samples had titres of 1/16 or greater. Seropositive animals were distributed throughout all the areas studied. The possible factors affecting the distribution of seropositive sheep in one of the areas are discussed.
