Secondary lysosomes dock only with phagoacidosome membrane at a distance of 40nm. As during acidosome fusion with phagosomes, fusion of the many lysosomes with the phagoacidosome occurs at nearly the ...

The bottom of the buccal cavity is surrounded by specialized cytoplasm and contains a lip that constricts the opening leading through the cytostome into the receiving vacuole or nascent vacuole. The ...

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...

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 ...

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...

This group represents a serial series of sections. At the level of this section, the bottom of cytopharyngeal tube with one cilium remaining. End of macronucleus, three membranelles of the pek, and ma...
