Using microscopy and molecular community analysis techniques, the effects of antifouling methods will be assessed.
This project will assess the cleanliness of existing endoscopes and the efficacy of current decontamination procedures, using a new highly sensitive microscopy imaging method to identify and quantify residual contamination from a range of flexible endoscopes, and new cell assays to assess potential prion infectivity.
Touch surfaces are an important conduit for transmission of bacteria, viruses and fungi, leading to mass outbreaks of disease in the community and healthcare acquired infections by multiple antibiotic resistant microorganisms causing great morbidity and mortality.
The objective of the work developed by the partner University of Southampton is to firstly optimize the formation of L. monocytogenes biofilms and then conduct experiments to calculate the detachment forces required to remove L. monocytogenes biofilms.
To evaluate the potential of Cold Atmospheric Plasma as a tool for the decontamination of reusable surgical instruments and endoscopes, thus significantly reducing the risk of iatrogenic infections with prions and potentially other resilient agents.
Analysis of biofilms in the marine environment and of the effectiveness of antifouling strategies
Our Consultancy Service has dealt with a wide range of projects in collaboration with both small and large multinational companies.We offer a range of testing services using up-to-date microbiological methods and the latest techniques in specialised microscopy.
Using the model organism Pseudomonas aeruginosa to investigate mechanisms by which drinking water biofilms harbour important pathogenic microorganism and how these interactions within multi-species biofilms can enhance genetic adaptation and evolution of microbial pathogens.
Development of rapid, sensitive, advanced EDIC/EF light microscopy based protocols to assess the efficacy of current bio-decontamination systems.
Using a multicellular tumour spheroid model to investigate the role of hypoxia and DNA mismatch repair on the fundamental processes of importance in tumour development
Investigating the use of the signalling molecule nitric oxide for microbial control at the phylloplane
This work aims to design novel methodologies for the detection of low levels of contaminants, model the distribution of contaminants throughout a network and identify the point of origin, develop the use of sensors for surveillance and provide decontamination protocols for polluted networks and installations, including the neutralisation of contaminated water and residues.
Biofilm development on urinary catheters is a major healthcare issue, leading to infection and blockage. Here we are using advanced microscopy and viability techniques to improve our understanding of biofilm development and persistence on urinary catheters.
