[Effects of hydrostatic pressure per se and of inert gases on a Limax-type free-living amoeba: Acanthamoeba culbertsoni]. 1983

A M Simitzis-Le Flohic, and L Barthelemy, and C Chastel

The authors investigated the high hydrostatic and gas (nitrogen and helium) pressure effects on the morphology, missing encysting process and mortality rate of Acanthamoeba culbertsoni trophozoïtes. These studies have been performed by the means of scanning electron microscopy (SEM). It has been possible to show that the modulus of dissolving of both gas in water and oil is insufficient to explain the very important volumetric changes. Thereafter it appears that there is clathrate compounds formation.

UI	MeSH Term	Description	Entries
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
