[Observation of the processes of phagocytosis and digestion of Staphylococcus aureus by Trichomonas vaginalis using a transmission electron microscope].
Trichomonas vaginalis was incubated with bacteria for 30 min. After centrifugation of Staphylococcus aureus, incubation of T. vaginalis was continued for 40 min., 120 min. and 6 hrs. It was found that bacteria have been intensively phagocytated through whole surface of protozoan. Phagosome with bacteria at different stages of degradation, up to defecation of undigested residues were observed. It was observed that some bacteria, apparently not susceptible to digestion, were immersed directly in cytoplasm (outside vacuoles).
