Diagnostic System for Rapid and Sensitive Differential Detection of Pathogens Thomas Briese,*1 Gustavo Palacios,*1 Mark Kokoris,†1 Omar Jabado,* Zhiqiang Liu,* Neil Renwick,* Vishal Kapoor,* Inmaculada Casas,‡ Francisco Pozo,‡ Ron Limberger,§ Pilar PerezBrena,‡ Jingyue Ju,* and W. Ian Lipkin* Naturally emerging and deliberately released pathogens demand new detection strategies to allow early recognition and containment. We describe a diagnostic system for rapid, sensitive, multiplex discrimination of microbial gene sequences and report its application for detecting 22 respiratory pathogens in clinical samples.
fficient laboratory diagnosis of infectious diseases is increasingly important to clinical management and public health. Methods to directly detect nucleic acids of microbial pathogens in clinical specimens are rapid, sensitive, and may succeed when culturing the organism fails. Clinical syndromes are infrequently specific for single pathogens; thus, assays are needed that allow multiple agents to be simultaneously considered. Current multiplex assays employ gel-based formats in which products are distinguished by size, fluorescent reporter dyes that vary in color, or secondary enzyme hybridization assays. Gelbased assays are reported that detect 2–8 different targets with sensitivities of 2–100 PFU or
