[Electronenmicroscopic Studies on Cells of Listeria monocytogenes Treated with Enterocin (author's transl)]. 1977

J Krämer, and W Lenz, and A Viebahn, and H Brandis

Purified enterocin E1A, a bacteriocin produced by Streptococcus faecium E1, had a strong bactericidal activity on susceptible cells of Listeria monocytogenes. Electronmicroscopic observation of thin sections of L. monocytogenes, treated with enterocin E1A at a concentration that gave 0.1% survivors, revealed that the predominant features of morphological alterations concern the partial dissolution of the cell content and the damage of the cell envelope which enabled an efflux of cell-material. Not frequently intact protoplasts and greatly elongated cells were observed.

UI MeSH Term Description Entries
D008089 Listeria monocytogenes A species of gram-positive, rod-shaped bacteria widely distributed in nature. It has been isolated from sewage, soil, silage, and from feces of healthy animals and man. Infection with this bacterium leads to encephalitis, meningitis, endocarditis, and abortion.
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D001430 Bacteriocins Substances elaborated by specific strains of bacteria that are lethal against other strains of the same or related species. They are protein or lipopolysaccharide-protein complexes used in taxonomy studies of bacteria. Bacteriocin,Lantibiotic,Lantibiotics
D013291 Streptococcus A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
