  1. The analysis produced five independent components, each with a single coefficient that explained the vast majority (≥93.1%; or ≥0.9652) of the component variation. Hence each component was strongly associated with a single pathogen that is named in quotation marks. The five putative pathogens were Pseudomonas spp., Linepithema humile virus 1 (LHUV-1), Deformed wing virus (DWV), Kashmir bee virus (KBV), and Black queen cell virus (BQCV).
