Pseudomonas aeruginosa peritonitis

*Pseudomonas aeruginosa* peritonitis is a severe, opportunistic intra-abdominal infection of the peritoneum caused by the Gram-negative aerobic bacillus *Pseudomonas aeruginosa* It most commonly arises in vulnerable patient populations, notably individuals undergoing peritoneal dialysis or those who have experienced postoperative abdominal complications, catheter-related biofilm colonization, or prior broad-spectrum antimicrobial exposure Clinically, the infection is defined by abdominal pain, t...

*Pseudomonas aeruginosa* peritonitis is a severe, opportunistic intra-abdominal infection of the peritoneum caused by the Gram-negative aerobic bacillus *Pseudomonas aeruginosa* Pathophysiologically, the organism's intrinsic virulence factors, tendency to form resilient biofilms on indwelling biomaterials, and broad antimicrobial resistance mechanisms make this form of peritonitis notoriously recalcitrant, frequently causing peritoneal membrane damage, catheter loss, and persistent infection

It most commonly arises in vulnerable patient populations, notably individuals undergoing peritoneal dialysis or those who have experienced postoperative abdominal complications, catheter-related biofilm colonization, or prior broad-spectrum antimicrobial exposure

It most commonly arises in vulnerable patient populations, notably individuals undergoing peritoneal dialysis or those who have experienced postoperative abdominal complications, catheter-related biofilm colonization, or prior broad-spectrum antimicrobial exposure

Clinically, the infection is defined by abdominal pain, tenderness, systemic signs of inflammation, and cloudy peritoneal effluent exhibiting significant neutrophilic pleocytosis

Pathophysiologically, the organism's intrinsic virulence factors, tendency to form resilient biofilms on indwelling biomaterials, and broad antimicrobial resistance mechanisms make this form of peritonitis notoriously recalcitrant, frequently causing peritoneal membrane damage, catheter loss, and persistent infection
