The Adelaide Biofilm Test Facility (BTF) aims to improve the treatment and prevention of biofilm-associated diseases by providing adequate testing methods to the biomedical research community.
The BTF is South Australia’s first test facility for antimicrobial agents, pharmaceutical preparations, dressings, materials and coatings. Located within the Sansom Institute and headed by Dr Nicky Thomas the BTF tests materials for their ability to inhibit or remove microbial biofilms.
What we offer
The Adelaide Biofilm Testing Facility provides standardised biofilm models for industry, academia, and health care providers. We also offer customised solutions to meet specific requirements of our clients. Please contact Dr Nicky Thomas for further information.
The following are examples of models that are available for testing:
- High throughput multi-titer plate based biofilm model
- Calgary biofilm device
- Colony biofilm model
- Artificial skin biofilm model
- Flow cell biofilm model
- Tube biofilm model
- in vivo whole animal biofilm and toxicity model (C. elegans)
What are biofilms?
Bacteria can exist in two forms - either as free floating cells or as immobilised, surface-attached cells. Once bacteria have attached to a surface they rapidly colonise the surface forming a dense network of bacteria. The production of a complex matrix, or ‘slime’, protects the residing bacteria from external insults such as antibiotics, heat, and radiation.
Where do you find biofilm?
Biofilms are the most successful form of life on Earth, colonising both living and non-living surfaces. In the body biofilms can be found as plaque on the teeth, which needs to be physically removed by brushing teeth to prevent dental cavities. However, biofilms also colonise less accessible areas such as the nose and sinuses, wounds, lungs, catheters and implants making effective treatment significantly more challenging.
We select biofilm models for a given application to mimic reality as close as possible to provide meaningful answers to our customers.
Did you know that biofilms
- cause 80% of infectious diseases?
- are up to 1000-fold less sensitive to antibiotics?
- facilitate the communication between bacteria by chemical cues (“quorum sensing”)?
- are an important contributor to antibiotic resistance thereby posing a tremendous global challenge?
