. ''D. tsuruhatensis'' is an opportunistic and emergent pathogen. All documented infections are healthcare-associated.

Biology and biochemistry

Cells are slightly curved, short rod-shaped cells that occur singly or in pairs. Cells are 0.7-1.2 μm wide and 2.4-4.0 μm long. ''Delftia tsuruhatensis'' can degrade phenolic compounds and aniline, which are often pollutants of soil and water.

Biofilm interactions

''Delftia tsuruhatensis'' can inhibit quorum sensing and biofilm formation, which could inform new therapeutic drugs against antibiotic-resistant bacteria. ''D. tsuruhatensis'' demonstrated significant quorum sensing inhibition and suppression of biofilm formation against ''Pseudomonas aeruginosa'' and other pathogens''.'' These activities also cause ''P. aeruginosa'' to be 2-3 times more susceptible to antibiotics.
