Delftia tsuruhatensis

Delftia tsuruhatensis is a Gram-negative, rod-shaped, catalase- and oxidase-positive, motile bacterium from the Comamonadaceae family, which was isolated from a domestic wastewater treatment plant in Japan.[3] D. tsuruhatensis is an opportunistic and emergent pathogen.[4] All documented infections are healthcare-associated.[4][5][6]

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.[3]

Delftia tsuruhatensis can degrade phenolic compounds[7] and aniline,[8] 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.[9] D. tsuruhatensis demonstrated significant quorum sensing inhibition and suppression of biofilm formation against Pseudomonas aeruginosa and other pathogens.[9][10] These activities also cause P. aeruginosa to be 2-3 times more susceptible to antibiotics.[11]
