Dynamic and ultrastructural studies of in vitro interaction between Toxoplasma gondii and cultured cell lines. I. Adhesion and cellular penetration.
Toxoplasma gondii is a protozoan parasite that requires an intracellular environment for growth and replication. This study describes the early phase of the interaction between the parasite and its host cell. With the aid of phase contrast microcinematography, it has been possible to observe adhesion to cell membrane, and the closely following intracellular penetration. This report also reviews the ultrastructural and biochemical grounds that could account for the infecting process.
