 Full genome sequence of an environmental isolate, "S. maltophilia" R551‑3, and a clinical isolate, "S. maltophilia" K279a, are available.Both strains contain genes that encode type I pili, which have been implicated in adhesion and the early stages of biofilm formation, and type IV pili, which have been implicated in adherence, auto-aggregation, twitching motility and biofilm formation.Conserved distribution of pili-coding gene clusters in sequenced genomes may indicate similarities in the plant and animal colonization strategies.
