Molecular Diagnostics
The Molecular Diagnostics Research Group (MDRG) at NUI Galway has 20 years experience and an international track record of achievement in the development and application of molecular diagnostics tests for microbial species identification.
- Molecular diagnostic target discovery
- Nucleic acid based test design
- Nucleic acid test platform technologies development
- Collaborative or contract R&D with industry
- External sequence conservation enabling universal amplification of the target region
- Internal nucleic acid sequence variability enabling the design of bacterial and fungal genus and species-specific NATs as appropriate to the test application
- High copy number RNA target (RiboSEQ, MycoSEQ) providing increased test sensitivity
The group has also designed and developed assays for marine microorganisms through a Marine Strategic Research programme undertaken in collaboration with the Irish Marine Institute. The applied research project developed a portfolio of real-time PCR tests for the identification of key harmful bloom species (HAB) that can occur in Irish waters. These tests have been transferred into the Marine Institute and are being used to support the national phytoplankton monitoring programme. The group also led the development of qPCR methods for identification and quantification of HAB species relevant for European waters as part of an EU project (EU SPIES-DETOX) involving academic and industry partners.
The MDRG has also led a joint molecular and clinical exploration of mycoplasmas and other bacteria that may play key roles in triggering multiple sclerosis (MS). The project, a collaboration with Neurology Professor Edward Hogan of NUI, Galway and the Institute of Molecular Medicine and Genetics, Augusta, Georgia, USA, applied molecular probes to detect traces of Mycoplasma DNA in human MS tissue samples.
The MDRG team is currently developing nucleic acid diagnostic assays for use on biosensor platforms that utilize a variety of transduction mechanisms. These include a variety of optical and electrochemical detection systems as well as novel solutions that utilize next generation labels such as nano-particles, nano-spheres and quantum dots. The use of micro-fluidic systems to enhance assay sensitivity is also being explored.
As part of the on-going expansion of its core capabilities the MDRG is part of an academic collaboration with the Biomedical Diagnostics Institute (BDI) at DCU. The BDI carries out cutting-edge research focused on the development of next-generation biomedical diagnostic devices measuring indicators of disease. MDRG brings to this collaboration its extensive range of technologies and expertise in assay design and development.
MDRG technologies have been successfully commercialised through licensing agreements and co development collaborations with both indigenous and multinational diagnostics companies.
The groups first major industrial collaboration was with Roche Molecular Systems and Innogenetics N.V. Using the Spacer Probe technology a range of assays for fungal organisms involved in sepsis were developed by the MDRG team. The assays were incorporated into the LightCycler ® SeptiFast kit which Roche launched onto the market in 2006. The test is designed to detect and identify the 25 most important bacterial and fungal species causing bloodstream infections.

The second industrial collaboration was with major European IVD company. Again MDRG developed through to feasibility a range of assays for the company's chosen platform. The MDRG technologies used in this collaboration were RiboSEQ and MycoSEQ.
The third and most recently completed industrial collaboration was with Beckman Coulter. This major programme involved the MDRG team developing a range of assays for both bacterial and fungal agents using the RiboSEQ and MycoTECH technologies. These assays have been transferred to the Beckman Coulter platform which will be launched onto the European market in 2012.
In the Irish context, the group is involved with a SME which is currently developing new niche products for the molecular diagnostics market. This Innovation Partnership is funded through Enterprise Ireland.
The experience the group has gained in working with multinational companies has strengthened our capability in nucleic acid test development. We believe this capability is core to our continued interaction with industry both nationally and internationally.
Information on the patent status of each of these technologies is available in the Patent section.
