Biofilms Antimicrobial Susceptibility Testing

Biofilms Antimicrobial Susceptibility Testing

Biofilms cause resistance to many antimicrobial agents. The result of indwelling biofilms on medical devices is recurring, untreatable infections and medical device failure. To overcome chronic and recurrent infections, it is important to detect microbial biofilms and determine their antimicrobial susceptibility. In addition, identifying genes involved in biofilm formation and measuring gene expression due to anti-biofilm and antibacterial activity of agents may be beneficial in biofilm research. Now, CD BioSciences provides you with a variety of biofilms antimicrobial susceptibility testing services to meet your scientific research needs.

Biofilm Antimicrobial Susceptibility Testing Approaches We Offer

  • MBEC assay
    We determined the biofilm remaining after eradication by the agent by the microtiter plate method, according to the MtP method to form bacterial biofilms lining the well walls. The MBEC assay is a quantitative method for measuring biofilm production by a microplate reader.
  • Microtiter plate assay indicating biofilm production.Figure 1. Microtiter plate assay indicating biofilm production. (Krmusaolu S.2019)

  • bMIC and bMBC assays
    We determined bMIC and bMBC by plate count method. The lowest agent concentration at which bacterial growth was lower than or equal to the control was determined as the biofilm's biofilm minimum inhibitory concentration (bMIC). bMIC50 and bMIC90 represent the lowest concentration of drug that inhibits 50% and 90% of biofilm-embedded bacteria. After incubation, the lowest agent concentration at which the biofilm-embedded bacterial colonies did not grow was determined as the biofilm minimum bactericidal concentration (bMBC) of the biofilm agent.
  • Other methods we offer
  • Instruments Substratum Method
    CDC biofilm reactor Plastic connectors Direct or viable counting, after coupons are sonicated, vortexed, and homogenized
