title: [Possible entry of fragments of a bacterial genome into the trophozoite nucleus of the dysentery amoeba].
abstract: The use of Fölgen-like electron microscopy reaction has revealed particles in the cytoplasm and nucleus of the dysentery amoeba trophozoites which in their size and resistance to acidic hydrolysis and in their affinity for uranilacetate are similar to tightly packed elements of the bacterial genome. On this basis a conclusion was drawn that some fragments of genomes of phagocytic bacteria can be preserved in the amoebal cell. The community of microorganisms consisting of trophozoites of the dysentery amoeba and bacteria of the intestinal flora is supposed to be a suitable model for studying the possibility of penetration of transgenetic elements from procaryote to eucaryote.
