Key: Genes encoded by: aafA = structural subunit of the aggregative adherence fimbriae I (AAF/I), aap = antiaggregative protein (dispersin), aggA = structural subunit of the aggregative adherence fimbriae II (AAF/II), aggR = aggregative adherence regulator, pet= plasmid-encoded enterotoxin, pic= mucinase,
