Protozoa, including P. multimicronucleatum, unlike most cells, have tubular cristae in their mitochondria. Tubular cristae, however, do occur occasionally in higher organisms such as in the lutein cel...

Vestibular kinities and the cortical architecture adjacent to the oral apparatus of Conchophthirus curtus. The negative magnification is 15,500X. The raw film was scanned with an Epson Perfection V750...

A view of the left side of Conchophthirus curtus. See Antipa, G. A. and Small, E. B. 1971. A redescription of Conchophthirus curtus Engelmann, 1862 (Protozoa, Ciliatea). J. Protozool. 18:491-503 for m...

Electron micrograph of a thin section of fixed, embedded stained cells of Peranema trichophorum. Shown is a section of the "rodorgan', a bundle of 13-protofilment microtubules with pseudo-hexagonal sy...

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 nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

Conchophthirus was deciliated by calcium ion shock followed by shearing through a micropipette. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In this i...
