Microarray systems for microbial detection and identification / by B.N. Ford and D.E. Bader. : D68-4/203-2010E-PDF

The relatively recent availability of complete or near-complete sequences of microbial DNA makes it possible to find and exploit unique genetic markers for most microbes. Using microbial genome sequences from public databases, a high-density microarray system has been developed which should enable the identification of hundreds of individual species or strains of pathogenic microorganisms on a single assay platform. This report summarizes the design, development, and testing of this microarray design. The system is currently capable of discriminating multiple human pathogens, Category A biothreats, and some agricultural pathogens, other using supervised analysis methods. Ongoing development will include tools for automation of analysis, and extension of the testing panel of microbes.
