title: [Electron microscopic study of pathogenic bacteria on environmental objects].
abstract: The morphological picture of different bacteria (Salmonella typhimurium, Proteus vulgaris, Klebsiella pneumoniae, Pseudomonas aeruginosa, Yersinia enterocolitica O3, Y.pseudotuberculosis 1, Y.frederiksenii, Y.intermedia, Y.kristensenii) on environmental objects was studied with the use of scanning electron microscopy (SEM). Bacteria adhered to the surface of pieces of fodder, egg shell, cabbage leaves and form microcolonies, whose morphology was similar to colonies, grown on nutrient media. The cells produced extracellular substances, seen in SEM as integuments. These integuments were gourd to protect the population from the action of unfavorable factors.
