Upon electron bombardment, some elements, such as P, show an electron energy loss profile with a peak at a specific energy loss value. By collecting a series of images of a field at different energy l...

A fracture of an apparently fully formed trichocyst showing that the body of paracrystalline material fills the organelles lumen and is bound to the membrane by a loose array of threads. The membrane,...

The tip of the trichocyst does not expand but remains nail shaped and remains bound to the elongated shaft. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0....

QF-DE of a crystal whose P-fracture face shows many IMPs similar to the P-face of an acidosome lying nearby and trichocyst as well as trichocyst precursor vesicles. TEM taken by C. Schroeder on 6/3/8...

A frame from the grouped movie of a Balamuthia mandrillaris ameba within a culture of monkey kidney cells. Accompanying photographs are enlargements of the tips of pseudopodia to demonstrate their fle...

A single frame from the movie (CIL:20154) that shows a large rounded monkey kidney cell being penetrated by a pseudopodium followed by the whole Balamuthia ameba. Detection of the ameba within, rather...

Naegleria fowleri is a free living amoebae that can be an opportunistic pathogen, and in some cases, has been diagnosed as the causative agent of the usually fatal amebic encephalitis. Other opportuni...

An ameba, Balamuthia mandrillaris, within a culture of monkey kidney feeder cells. Balamuthia extends from its branched pseudopodia while its rope-like body curves over and around a nucleus of a kidne...

Larger vesicles contain paracrystalline cores that are associated at one end with the trichocyst membrane. This may mean that there is a site on the membrane that promotes paracrystalline formation or...
