Perfectus Biomed Group are excited to announce that we have recently received UKAS 17025 accreditation for the extension to scope for the Single Tube Method to include Candida albicans as a test organism. We are industry leaders in biofilm testing methods, please contact us to discuss how we can help you with your microbiological requirements, email@example.com.
In 2020 we received accreditation for this method using Staphylococcus aureus and Pseudomonas aeruginosa, UKAS have now granted us an extension of scope to include the addition of Candida albicans. The Single Tube Method from the ASTM E2871 – 19 standard is limited to bactericidal assessment against Staphylococcus aureus and Pseudomonas aeruginosa, Perfectus Biomed lead the market with the inclusion of Candida albicans to our UKAS accreditation, allowing us to now test the yeasticidal properties of surface disinfectants to the same highly validated and reliable standard.
Perfectus Biomed’s Method Validation Scientist, Hollie Leighton, lead the development and validation that gained us this accreditation. The purpose of the method is to determine the efficacy of disinfectants against C. albicans Biofilm. The efficacy of surface disinfectants is evaluated against mature biofilms grown for 48 hours in a closed-circuit system with a continuous supply of media.
Some organisms are capable of surface attachment and therefore they are capable of biofilm formation. These variations can be species specific, strain specific and even phenotype dependent. In order to assess the ability of an antimicrobial agent to either prevent biofilm formation or breakdown of an established biofilm, it is important to be able to grow reproducible biofilms. The method uses a CDC reactor system to produce specific biofilms on coupons under defined conditions which are suitable for efficacy testing.
A huge thank you to Hollie, and the team for their hard work and commitment to this project.
