Which organism is commonly implicated in PD-related peritonitis along with skin flora?

• A. Pseudomonas aeruginosa
• B. Staphylococcus aureus
• C. E. coli
• D. Enterococcus faecalis

Answer: (C)

PD-related peritonitis often starts with contamination during dialysis exchanges, so skin flora such as Staphylococcus species are the most common culprits. But many episodes also involve Gram-negative enteric bacteria, with Escherichia coli being one of the most frequent. E. coli can reach the peritoneal cavity through contamination at the catheter site or during exchanges and alongside skin flora organisms it remains a characteristic, common pathogen in these infections. This is why E. coli is considered a typical organism implicated in PD-related peritonitis.
