Abstract: | Plate count and spectrophotometric methods have been used to asses the ability of an organism to attach to different surfaces and form biofilms. In the present study we report a highly sensitive, specific and quick method to check the role of flagellin in bacterial adhesion to polystyrene. Flagellin from Stenotrophomonas maltophilia showed high affinity for polystyrene (P < 0.05), which decreased on pretreatment offlagellin with anti-flagellin in a dilution dependent manner. In an enzyme immunoassay format a positive correlation was detected between the anti-flagellin dilutions and flagellin attachment to polystyrene (correlation coefficient +0.860155). These evidences conclusively prove the involvement of flagella in the adhesion ofS. maltophilia to polystyrene surface and enzyme immunoassay, a quick and reliable method to check this phenomenon. |
