From: Oligoribonuclease mediates high adaptability of P. aeruginosa through metabolic conversion
orn deletion enhanced P. aeruginosa pathogenicity (n = 4). (a) Apoptosis of A549 cells Blank means add the medium. nc means normal control P. aeruginosa ATCC 27853 infected cells. Δorn means orn deletion strain infects cells. (b) Annexin V/PI double marking A549 apoptosis test. (c) After three days of bacterial infection, the wound tissue HE staining. PBS was a blank control. (d) Adhesion of bacteria to A549 cells. Significance tested with two-sided student’s t test. **** p < 0.0001. (e) Wound tissue bacterial count. Significance tested with two-sided student’s t test. * p < 0.05
