Gritsenko V.A., Zhurlov O.S., Andreychev V.V. ANALISIS OF INTERCONNECTION OF SERUMRESISTENCE AND PHYSICO-CHEMICAL PROPERTIES OF ESCHERICHIA COLI WITH THEIR ABILITY TO FORM BIOFILMS [№ 4 ' 2012] The article includes materials about variability of 45 strains Escherichia coli from patients with infectious-inflammatory diseases of an urogenital tract and biliary ways to serumresistence, integral physico-chemical properties (hydrophobicity, electrokinetic potential — z-potential) and ability to form biofilms. Bacterial isolates forming biofilms and "biofilm" fraction of E. сoli are less resistant to bactericidal activity of serum and more hydrophobic, than isolates E. coli not forming biofilms, and cells from "planktonic" fraction was established.
Zhurlov O.S., Gritsenko V.A., Brudastov Yu.A. INFLUENCE OF CULTIVATION TEMPERATURE ON PHYSIOLOGICAL AND PHYSICAL-CHEMICAL FEATURES OF ESСHERICHIA COLI К12 [№ 12 ' 2009] The analysis of influence of cultivation temperature on the dynamics of reproductive capacity and physical-chemical features (hydrophobicity, z-potential) of Essherichia coli K12 in periodic cultures is presented in this article. Chronological conjugacy changes of these features are observed at the optimal temperature of 37?C of Escherichia. Adaptation of E.coli to the sub- and supraoptimal temperature (27?C and 42?C) is accompanied with a marked modification of the analyzed characteristics and desynchronization of their dynamics.
Brudastov Yu.А., Zhurlov О.S., Kolinichenko Е.V., Grudinin D.А. ACTIVE OXYGEN METABOLITES IN THE PHAGOCYTOSIS [№ 12 ' 2008] The work provides up-to-date data on the role of active oxygen metabolites in the phagocytosis. Special authors' attention is given to the sequence of the activation of the oxygen-dependent mechanisms in the phagocytes and comparative effectiveness of the bactericidal action implemented by most significant oxygen radicals.
Zhurlov О.S., Kolinichenko Е.V., Grudinin D.А., Brudastov Yu. A. RESISTANCE OF MICROORGANISMS TO SUPEROXIDANION, NITROGEN OXIDE AND PEROXINITRITE AS A FACTOR OF THEIR SURVIVAL IN THE PHAGOCYTOSIS [№ 12 ' 2008] Through using 23 cultures of the Escherichia coli and 23 cultures of Staphylococcus aureus, with different levels of resistance to the active forms of oxygen gas (AFO; superoxidanion, nitrogen oxide and peroxinitrite), the study determined parameters for variability of the bactericidal action implemented by the human blood neutrophils under standard phagocytosis conditions in vitro. On this basis a comparative study was undertaken to assess the contribution from the bacteria ferments-antioxidants and their resistance to AFO in the process of survival under phagocytosis.
Bachurskaya N.S., Brudastov Yu.A., Zhurlov O.S. HYDROPHOBIC FEATURES OF MUSHROOMS OF MALASSEZIA TYPE [№ 12 ' 2006] Data about hydrophoby of Malassezia type mushrooms surface isolated from patients with dandruff by branny herpes and seborrheic dermatitis are given in this work. It is shown that mushrooms of Malassezia type distinguished from patients with surface mycosis of skin are characterized with expressed hydrophoby in whole. At the same time reliable pathovariant differences of Malassezia mushrooms at hydrophile-lipophilic balance of their surface are observed. Both as hydrophoby as variability at this feature of Malassezia mushrooms are decreased in the line of microorganisms cultures groups: "dandruff - branny herpes - seborrheic dermatitis".
Zhurlov O.S., Gritsenko V.A., Chernikov D.A., Gritsenko Ya.V. MORPHOLOGIC-PHYSICAL AND PHYSICAL-CHEMICAL MANIFESTATIONS OF ESCHERICHIA’ ADAPTATION TO BILE AND CATION ANTIMICROBIAL PROTEINS [№ 12 ' 2006] Experimental data revealing peculiarities of changes of morphological-physical and physical chemical characteristics of escherichia at their adaptation to bile and cation antimicrobial proteins of human leucocytes and thrombocytes are given in this article. Key words: Escherichia coli, bile, cation antimicrobial proteins, leukodefencines, thrombodefencines, adaptation, electro-kinetic potential, hydrophoby.
Brudastov Yu.A., Gritsenko V.A., Zhurlov O.S., Brudastov A.N. PROPERTIES OF ESCHERICHIA COLI AS FACTORS OF TRANSLOCATION FROM BOWELS TO INNER ORGANS [№ 5 (app.1) ' 2005] It is shown on the models of E.coli translocation from bowels to inner organs of mice that the change with symbiont (parasite) of habitation epitope is accompanied with clones selection and savings with more evident capability to inactivation of complement, lysozyme and intercede, bigger activity of catalase and lesser hydrophobicity, which allows to put these properties to factors of bacterial translocation. Positive dynamic of described features in bowels subpopulation of echerihiya at translocation, allows to suppose the forming of conditions for support of its dysbiotic condition due to translocated bacteria recolonization in bowels microbiocenose.
