Systemic infection with an unidentified Toxoplasma-like protozoan in a neonatal Lichtenstein's hartebeest (Sigmoceros lichtensteinii)

Abstract

An unidentified Toxoplasma gondii-like disseminated infection was found in tissues of a 2-day-old hartebeest. Protozoal tachyzoites were about 3.5 x 1.7 Microns, had electron-dense rhoptries, and divided by endodyogeny. The organism did not stain with polyclonol antibodies to T. gondii, Neospora caninum, or Sarcocystis cruzi.
