“…All isolates were susceptible to cefepime, ciprofloxacin, piperacillin-tazobactam, and carbapenems [4]. Although treatment frequently required foreign device removal [5], recent reports indicate that early and appropriate antibiotic therapy may allow catheter salvage in catheter-related R. radiobacter peritonitis [6]. R. radiobacter isolates should be evaluated in the appropriate clinical context as pseudo-outbreaks have been reported due to nonsterile processing equipment and/or handling of laboratory specimens [7].…”

Peritoneal dialysis catheter-related peritonitis is typically related to catheter insertion or hygiene. Organisms usually manifest as gram positive organisms typically Staphylococci or gram negative bacilli that typically colonize aqueous environments such as Pseudomonas spp. as well as other unusual mycobacterial or fungal pathogens. The authors present a unique case of peritoneal dialysis catheter-related peritonitis manifesting after the patient's cat bit the proximal aspect of the catheter attachment tubing. After failure to clinically improve after outpatient treatment of Staphylococcus hemolyticus and Staphylococcus capitis catheter related-peritonitis with intraperitoneal Vancomycin and empiric Gentamicin, repeat peritoneal cultures were sent that demonstrated growth of Rhizobium radiobacter. The patient was admitted inpatient and treatment was tailored to intraperitoneal Cefepime with clearance of peritoneal cultures and rapid improvement in peritoneal white blood cell count and the patient's clinical condition. The patient was subsequently discharged on oral Ciprofloxacin with complete recovery and catheter salvage.

“…A similar outcome was reported by Rothe & Rothenpieler (2007) in a multidrug-resistant strain of R. radiobacter causing peritonitis in a 41-year-old Caucasian male with ESRD. However, preservation of the catheter was reported by Tsai (2013) in a patient with IgA nephropathy maintained on intraperitoneal ceftazidime for 3 weeks.…”

Background:Rhizobium radiobacter is an opportunistic human pathogen in debilitated patients with foreign plastic intravascular devices and peritoneal dialysis (PD) catheters. We performed a Medline search of the English-language literature on R. radiobacter continuous ambulatory peritoneal dialysis (CAPD) peritonitis in end-stage renal disease (ESRD) and reviewed 13 cases.Case presentation:A 54-year-old male with ESRD secondary to chronic long-standing type II diabetes mellitus presented to the nephrology outpatient department with fever, abdominal pain and cloudy PD effluent. The patient was admitted to the hospital. PD fluid was sent for cell count, Gram stain and culture. The white blood cell (WBC) count in the PD fluid was 6400 mm−3 with 82 % neutrophils. Gram staining of the fluid showed plenty of Gram-negative bacilli. A presumptive diagnosis of CAPD peritonitis was made and empiric intraperitoneal cefazolin and tobramycin were started. The PD fluid culture grew non-fermenting, Gram-negative bacilli identified as R. radiobacter. Empiric antibiotic therapy was continued and the patient’s abdominal pain subsided. The peritoneal fluid counts decreased to 50 WBCs mm−3 on day 4. However, his abdominal pain recurred on day 8 and his PD fluid count increased to 300 cells mm−3. The catheter was therefore surgically removed.Conclusion:Although R. radiobacter is considered a contaminant, it can cause relapsing symptomatic peritonitis peritoneal catheter removal.

“…3 In patients with chronic renal disease, R. radiobacter has been rarely reported on peritoneal treatments; in 64% of these cases, catheter was removable, but currently there is a controversy if to achieve catheter rescue. 4 On hemodialysis patients with CRBSI, there is only a reporting about A. radiobacter from Hanada et al 5 We report a new case where a 77-year-old man was admitted to our Renal Unit to perform regular hemodialysis treatment. The patient was suffering from renal neoplasia with end-stage renal disease treated by hemodialysis through TCVC in right jugular vein.…”
