In vitro activity of antibiotics at sub-inhibitory concentrations against biofilm formation by S. pseudintermedius strain DSM 25713. Biofilm biomass formed during 24 h-incubation was measured, using the crystal violet assay, in the presence of antibiotics at concentrations equal to 1/2x, 1/4x, and 1/8xMIC. Results were plotted as percentage of biofilm biomass formed in the presence of antibiotic, compared to controls (not exposed, 100 % biofilm biomass) (n = 6). The dotted line indicates a reduction in biofilm biomass of at least 20 % vs control (p < 0.001, chi-square test)
