Prevalences of microorganisms among samples from the STEFI study. Horizontal bars represent the number of plants contaminated (out of 19). Black bars, Gram-positive bacteria; gray bars, Gram-negative bacteria (dark gray, Pseudomonas spp.); white bars, fungi. To facilitate graphical representation, genera or species were grouped as follows: Acinetobacter johnsonii and Acinetobacter spp. were grouped as Acinetobacter spp.; Cellulosimicrobium spp., Cellulomonas spp., Dietzia spp., Brevibacterium spp., Gordonia spp., and Leucobacter spp. were grouped as Actinomycetales (except Mycobacterium spp.); Aeromonas spp. and Shewanella putrefaciens were grouped as Aeromonadales; Bacillus simplex, Bacillus spp., Paenibacillus glucanolyticus, and Aerococcus spp. were grouped as Bacillales and Lactobacillales; Brevundimonas diminuta and Brevundimonas spp. were grouped as Brevundimonas spp.; Alcaligenes faecalis, Achromobacter xylosidans, Comamonas aquatica, and Delftia spp. were grouped as Burkholderiales; Empedobacter brevis, Wautersiella falsenii, Sphingobacterium mizutaii, Sphingobacterium spp., and Chitinophaga spp. were grouped as Flavobacteriales and Sphingobacteriales; Pseudochrobactrum spp., Agrobacterium tumefaciens, Methylobacterium spp., and Azorhizobium spp. were grouped as other Rhizobiales; Stenotrophomonas maltophilia and Stenotrophomonas spp. were grouped as Stenotrophomonas spp.; Pseudomonas fluorescens, P. azotoformans, and P. synxantha were grouped as Pseudomonas fluorescens complex; P. pseudoalcaligenes, P. mendocina, P. oleovorans, and P. alcaliphila were grouped as Pseudomonas pseudoalcaligenes complex; P. plecoglossicida, P. monteilii, and P. putida were grouped as Pseudomonas putida complex; Absidia spp., Acremonium spp., Aspergillus fumigatus, Paecilomyces lilacinus, Lecytophora hoffmannii, and Cladosporium spp. were grouped as other filamentous fungi; and yeasts were composed of Candida parapsilosis, Candida lipolytica, Candida guilliermondii, Candida spp., and Cryptococcus laurentii.
