Morphological appearance of Toxoplasma gondii in tissue cultures and tissues of various hosts

Abstract

Tissues from mice infected with the RH or Beverley strain were used to inoculate tissue culture, chick embryos and mice. Schizont-like structures were demonstrated in the former two systems as well as in chicks infected during embryonic life. Ring and partial ring arrangements as well as rosettes were also demonstrated in tissue culture. An interesting cytoplasmic mass with 4 nuclei as one developmental stage inside a cyst was found in a mouse brain.
