Fig 4 Evaluation of the influence of compound 1 and 3 on E. Four critical factors influencing the outcome of antibacterial testing were identified in a series of experiments: Generate a file for use with external citation management software.
Scrutinizing the protocols used by the different participants and identifying the factors influencing the test outcomes the approach was unified. Bactericidal materials gained interest in the health care sector as they are capable of preventing material surfaces from microbial colonization and subsequent spread of infections.
Add to My Bibliography. Images from this his. Therefore, a round robin test for evaluating antimicrobially active biomaterials had to be established.

AFM measurements of the PA6 control acompound 1 b and compound 3 c. However, commercialization of antimicrobial materials requires proof of their efficacy, which is usually done using in vitro methods.

Experiments were performed in nutrient broth diluted 1: Surface roughness is depicted in a range from jjs to nm. Note that the R values were calculated to the growth controls at the respective time points to avoid bias.
Didn’t get the message? Abstract Bactericidal materials gained interest in the health care sector as they are capable of preventing material surfaces from microbial colonization and subsequent spread of infections.
Supplemental Content Full text links. Fig 3 Assessment of the physiological state of the microorganisms on the outcome of antibacterial testing of compound 1 and 3.
The first round of testing showed that analyses in the different laboratories yielded different results, especially for materials with intermediate antibacterial effects distinctly different efficacies were noted.
Determination of the antibacterial effect of compound 1 and 3 on E. In conclusion, to enable assessment of the results obtained it is necessary to evaluate these single parameters in the test protocol carefully.
