Abstract. Recent advances in the detection of plant pathogens using immunological and nucleic acid-based techniques has enabled the major genera and species of disease-causing organisms to be quickly and reliably identified. BACKGROUND: The time required for bloodstream pathogen detection, identification (ID), and antimicrobial susceptibility testing (AST) does not satisfy the acute needs of disease management.
