A commercial vaccine for ovine toxoplasmosis

  • D. Buxton (a1) and E. A. Innes (a1)


This paper describes the development of the first commercial vaccine for toxoplasmosis. The vaccine comprises live tachyzoites of the S48 ‘incomplete’ strain of Toxoplasma gondii and is deployed to control toxoplasma abortion in sheep. A discussion of protective immune mechanisms and recent studies on host responses to the vaccine is also included.
