Multiplatform Approach for Microbial Biomarker Identification—Microbial biomarkers were directly or indirectly identified from samples collected from an infected host, in the case of this study, a macaque model of infection. Techniques used for direct detection of microbial biomarkers included mass spectrometry (MS) of concentrated or enriched samples and protein array. Indirect detection included the InMAD strategy coupled with protein array and immunoprecipitation-coupled MS. Identified biomarkers were categorized based upon the number of times each was identified by either direct or indirect analysis. The image of the mass spectometer was copied from the thermo website (https://www.thermofisher.com/order/catalog/product/ULTIM3000RSLCNANO).
