title: [Dynamics of enterococcal growth].
abstract: To study the morphology, structure and radial growth of colonies, a model CTJI table intended for the study and identification of spectrograms in qualitative and semiquantitative spectral analyses can be used in addition to an optical biological microscope and a binocular magnifier. Mobile enterococci can be sharply differentiated from immobile ones, and Str. faecalis from Str. faecium, by the structure of their colonies on a solid medium containing crystalline violet and 2,3,5-triphenyltetrazolium chloride. In some cases enterococcal colonies in primary inoculations can be mixed cultures. Under the identical conditions of cultivation the growth rate on culture media and the total weight of bacterial biomass is lower in mobile enterococci than in immobile ones. These signs can be used for the differentiation of mobile and immobile enterococci.
