The entire membrane of the phagolysosome does appear to have been changed into that similar to the lysosome membrane which bears a thick glycocalyx (polysaccharide coat) and no longer appears to be li...

Following digestion, that only occurs in the phagolysosome (DV-III), the membrane of these DVs undergoes extensive tubulation. These tubules are ~45nm in diameter and arise from the cytosolic surface ...

The tubules arising from late DV-III expand at their distal ends into rounded shapes. These expanded ends contain a glycocalyx like the secondary lysosomes and large IMPs also like secondary lysosomes...

The tubules arising from late DV-III expand at their distal ends into rounded shapes. These expanded ends contain a glycocalyx like the secondary lysosomes and large IMPs also like secondary lysosomes...

Only the macronucleus contains nucleoli which is the site of ribosomal RNA synthesis and ribosome subunit assembly. This EM also contains the distal end of the food vacuole forming cytopharynx which c...

Acid phosphatase is present in tubules retrieved from late DV-III. The tubules and rounded expansions arising as a result of late DV-III membrane retrieval contain an electron-opaque reaction product ...

Quick-freeze deep-etch images show a more three dimensional view of acidosomes surrounding a phagosome. Acidosomes are unique in that they contain indentations of their membrane. The lumen has a honey...

A high magnification view of the intimate docking of acidosomes with the phagosome is particularly apparent where the P-face of the acidosome lies against the E-face of the phagosome. Numerous large I...

The cytopharynx/nascent digestive vacuole (phagosome) has an E-fracture face containing a high number of IMPs. Interestingly these IMPs are sometimes organized into plaques where there are several sho...

This group represents a serial series of sections. At the level of this section the macronucleus, cytopharyngeal tube, food vacuoles, and perioral membranelle are evident. TEM taken on 3/12/71 by R. A...
