Perfectus Biomed offer a range of planktonic and biofilm biocide testing methods.
Disinfectant testing supports infection control in healthcare settings and in the community. Disinfectant testing methods ascertain the activity of antimicrobial agents under specified conditions.
Examples include BS EN 1276 and BS EN 13704 disinfectant standards, which evaluate the bactericidal and sporicidal activity of chemical disinfectants, respectively. These test methods can be used for products within the food, industrial, domestic and institutional industries.
We work with clients to generate evidence in support of products that consistently remove or inactivate pathogens. Our expert team of PhD microbiologists will work with you to discuss method adaptations or custom design disinfectant testing methods that meet with your requirement. We produce meaningful data by replicating ‘real life’ scenarios that demonstrate the efficacy of disinfectant products against potential pathogenic microorganisms, including those that exist within a microbial biofilm.

We can use the PMM to test for bacterial adhesion to and host cell toxicity of experimental devices.

Since much of the human genital tract is composed of mucosal tissue, the PMM can be used for predictive preclinical testing of compounds or products related to urogenital health.

Inflammation and Biocompatibility
The PMM offers a unique way to investigate inflammatory cytokine concentrations in a cost-effective manner. We can perform ELISAs and multiplex assays to determine whether experimental compounds are pro- or anti-inflammatory.

Mucosal tissue is an ideal environment for microbial growth, making the PMM an excellent application for testing the efficacy of products to treat infectious disease pathogens. We can test for efficacy against planktonic and biofilm infections with this model.
