	We are developing a diagnostic tool that enables the detection of a range of Gram-positive bacterial pathogens endemic in patients around the world. Currently detection of these pathogens ranges from a few hours to several days. The system will use genetically engineered ''Bacillus subtilis'', to detect a range of Gram-positive bacterial pathogens. Our principal targets at this stage are ''Staphylococcus aureus'', and ''Streptococcus pneumoniae''. We are also considering the detection of a range of ''Bacillus'' species, and ''Clostridium difficile''. This new system will enable visual detection of these pathogens within minutes. The bacteria will be detected by the specific quorum-sensing peptides that they secrete extracellularly. Detection of the quorum-sensing peptides will activate the expression of fluorescent proteins, viewable under U.V light, in our engineered ''B. subtilis'' chassis. This application would have importance not only in hospital settings, but also in the third world.

We are developing a diagnostic tool that enables the detection of a range of gram-positive bacterial pathogens endemic in patients around the world. Currently detection of these pathogens ranges from a few hours to several days. The system will use genetically engineered Bacillus subtilis, to detect a range of gram positive bacterial pathogens. Our principal targets at this stage are Staphylococcus aureus, and Streptococcus pneumonia. We are also considering the detection of a range of Bacillus species, Clostridium difficile, and Staphylococcus epidermis. This new system will enable visual detection of these pathogens within minutes. The bacteria will be detected by the Quorum sensing peptides that they secrete extracellularly. This will activate the expression of fluorescence proteins in our engineered Bacillus subtilis chassis that can be viewed under U.V light.
