Biofilm formation by representative strains on ManBSA. The fimbrial phenotype of the strains as determined by seroreactivity is as indicated by the shading of the columns: Grey, Fim+ and binds HEp-2 cells; striped, Fim+ and does not bind HEp-2 cells; black, Fim− and does not bind HEp-2 cells. S. Typhimurium SL1344 H3 transformed with the empty cloning vector is designated pGEM and is Fim−. *, P <0.00005.
