Accumulations of acidosome-like vesicles are sometimes found (in this case in a predividing cell) and in this micrograph provide further evidence for invaginations of the outer membranes. It appears t...

This time series stack shows an amoeba (Dictyostelium discoideum) trying very hard to ingest a yeast cell (Saccharomyces cerevisiae) that is slightly too large. (The yeast cell is a mutant with an elo...

A movie from the time series stack described below (CIL:812) shows an amoeba (Dictyostelium discoideum) trying very hard to ingest a yeast cell (Saccharomyces cerevisiae) that is slightly too large. (...

A DV-III contains a thick continuous glycocalyx (polysaccharide coat) on the luminal side of its membrane as well as paracrystalline material, both provided by the fused lysosomes. The latex beads ind...

In more extreme cases microfilamentous material builds up into a thick layer surrounding the DV-I membrane as well as the fusion sites between the acidosomes and the DV-I. A similar thick meshwork was...

Detail of acidosome docking sites at DV-IA planar view through the site where acidosomes are docked and/or fusing with a DV-I. These sites are labeled for the mAb specific for antigen L1. TEM taken on...

As with acidosome fusion with the DV-I, lysosome fusion with the DV-II also seems to occur nearly all at once resulting in a phagolysosome (DV-III) with a highly irregular surface. However, unlike the...

Immunogold label specific for Q2 antigen on discoidal vesicles. The same mAb used in CIL:36721 heavily labels discoidal vesicles and less heavily the cytopharyngeal membrane. A few gold particles are ...
