Toxoplasmosis in sheep, goats and cattle in central Ethiopia.

In a seroepidemiological survey using an indirect haemagglutination assay, the prevalence rate of toxoplasmosis in central Ethiopia was 22.9% of 899 sheep, 11.6% of 753 goats and 6.6% of 785 cattle. There were high titres of 1:256 or more which suggest current infections. These results indicate that toxoplasmosis may be an important cause of reproductive wastage in small ruminants. The public health significance of this disease is discussed. Improved hygiene and management could reduce the prevalence of the disease.
