List of common methodologies used in pathogen diagnosis in our lab


For each sample submitted to our lab, we use a set of detection methods rather than a single method to ensure that the diagnosis is accurate


Oomycete: Symptoms, culturing on artificial media, morphology, microscopy, DNA-based assays


Fungi: Symptoms, culturing on artificial media, fungal morphology, microscopy, DNA-based assays


Bacteria: Symptoms, bacterial ooze tests, culturing on artificial media, colony morphology, biochemical assays, antibody-based assays, and DNA-based assays


Viruses: Symptoms, antibody based assays, and DNA and RNA-based assays


Abiotic issues: Symptoms and previous descriptions


For new pathogens: In addition to the methods above, tests including Pathogenicity test and Hypersensitive response (HR) test may be conducted
