Comparative analysis of conversion of physicochemical properties of biofilm-forming bacteria resistant to the innate immunity factors

DOI: https://doi.org/10.29013/ESR-17-1.2-8-10

Pages: 8 - 10

Authors: Zhurlov O. S.

Abstract: We conducted a comparative analysis of conversion physicochemical properties of biofilm-forming bacteria that are resistant to the bactericidal activity of blood serum, lysozyme and fraction of low molecular weight platelet peptides. It was established that bacterial resistance to blood serum, lysozyme and low molecular weight platelet peptides correlates with low hydrophilic and high values of electrokinetic potential cells. The conversion of physicochemical properties of bacteria, during incubation with the innate immunity factors, has unidirectional character and contributes to the increase of hydrophilic cells. The shiftof physicochemical properties a bacteria increases in the range – E.coli < S.aureus < coagulase-negative staphylococci

Keywords: Escherichia coli, Staphylococcus aureus, coagulase-negative staphylococci, HLB (hydrophilic-lipophilic balance), electrokinetic potential
