Toxoplasmosis in ferrets.

Abstract Extract In 1986 I described an epidemic of congenital Toxoplasma-like disease in ferrets (1) . The protozoan was subsequently confirmed immunohistochemically as Toxoplasma (Dubey, personal communication) but this was not reported. I wish to report this fact now in light of the recent discovery of the protozoan Neospora caninum, which is morphologically similar to Toxoplasma gonii, but which can be distinguished immunohistochemically (2) . The life cycle of Neospora caninum is not yet known so it is of interest to establish the fact that the ferrets in our report were confirmed as having toxoplasmosis.
