Sphingomonas paucimobilis: a rare cause of peritoneal dialysis-associated peritonitis

Sphingomonas paucimobilis is an emerging Gram-negative bacillus that has been reported in both healthy people and immunocompromised hosts.Various infections in humans have been described, including peritoneal dialysis (PD)-associated peritonitis although most have been limited to sporadic case reports.The clinical course and outcomes are variable with a high antibiotic resistance and unpredictable antibiotic sensitivity.Therefore, more data are warranted to clarify its treatment management.Here, we report a rare case of PD-associated peritonitis due to S. paucimobilis in a patient successfully treated with both intraperitoneal and intravenous antibiotics.
