Abstract

A quantitative spectrophotometric method was developed to measure the removal and killing efficacy of antibiofilm agents. Biofilms of Pseudomonas aeruginosa or Staphylococcus epidermidis were grown in 96-well plates, treated with an agent, then stained with either the biomass indicator crystal violet or the respiratory indicator 5-cyano-2,3-ditolyl tetrazolium chloride. This rapid screening method is sensitive enough to elucidate concentration-response relationships as well as differences between species responses to treatments. Using these assays, agents can be ranked by their ability to remove or kill biofilm.
