A 60-year-old man with end-stage kidney disease on automated peritoneal dialysis (APD) presented with fever, abdominal pain and turbid peritoneal dialysis (PD) effluent for 2 days. Intermittent intraperitoneal cefazolin and gentamicin were started, but his abdominal pain persisted after 2 days, with PD effluent WCC 20 000/ l and PD effluent culture growing Gram-negative coccobacilli. PD effluent culture finally grew I Neisseria zoodegmatis i , sensitive to co-amoxiclav, ceftriaxone, cotrimoxazole, levofloxacin and tetracycline, negative for beta-lactamase, and resistant to azithromycin.
