| Abstract: | Tritrichomonas foetus ingests horseradish peroxidase, native ferritin, cationized ferritin, and 0.08 micron latex beads by a process which involves the formation of pinocytic vesicles. These vesicles fuse with each other and with lysosomes forming large vacuoles. Biochemical determinations on the ingestion of horseradish peroxidase and morphometric analysis on the ingestion of cationized ferritin covered latex beads indicated that T. foetus has high endocytic activity. The process of ingestion of the various tracers used was analyzed by transmission electron microscopy of thin sections and freeze fracture replicas. |
