Abstract: | Dependence of adhesion and colonization of hydrophilic and hydrophobic surfaces by Escherichia coli strains with different mobility and chemotaxis was studied using E. coli mot+che+, E. coli mot+che-, E. coli mot-che+. Primary adhesion was shown to correlate with mobility of cells and hydrophilic/hydrophobic character of their surface. Secondary adhesion correlated in addition with chemotactic characteristics of bacteria. E. coli populations were shown to vary in electrophoretic mobility and cells capability for adhesion and chemotaxis. |
