Phylogenetic analyses of Staphylococcus based on the 16S rDNA sequence and assignment of clinical isolates from animals

Investigation of silver-stained nucleoli has been made in mono- and binuclear rat hepatocytes of different ploidy. Morphometric parameters of nucleoli and cell ploidy (after silver removing and Feulgen staining) were measured by image analyzer "Videotest". It has been shown that the total area and total volume of nucleoli correlate with cell ploidy, but the found dependence deviates from the proportional one. Possible reasons of such a deviation have been discussed. Marked correlation of total area or total volume of nucleoli was detected between pairs of nuclei of binuclear hepatocytes, whereas between accidental pairs of mononuclear hepatocytes such correlation is practically lacking.
