Table 2 Top 75 associated genes with pirA and tdh presence. Gene annotations are shown along with their UniParc accession where available. For some genes, only a UniRef accession was available. Bars indicated number of isolates present/absent in positive (pirA + or tdh +) or negative (pirA- or tdh-) strains. For pirA, the top 75 non-pirA plasmid-associated genes are highlighted
