Abstract
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).
摘要
阴道毛滴虫与细菌共孵育30分钟。金黄色葡萄球菌离心后，阴道毛滴虫继续孵育40分钟、120分钟和6小时。发现细菌通过原生动物的整个表面被大量吞噬。观察到含有处于不同降解阶段细菌的吞噬体，直至未消化残渣排出。还观察到一些显然不易被消化的细菌直接浸入细胞质（液泡外）。
