Peritonitis due to Rhizobium radiobacter

Abstract

Rhizobium radiobacter (Agrobacterium radiobacter) is an aerobic Gram-negative rod belonging to Agrobacterium genus, a group of phytopathogenic bacteria present in the soil that has been implicated in human opportunistic infections. We report a clinical case of bacterial peritonitis in a 5-year-old child with chronic renal disease in peritoneal dialysis, who had a history of direct soil contact identified. The infection was treated with ceftazidime and piperaciline+tazobactam without relapses or the need to remove the peritoneal dialysis catheter.

Rhizobium radiobacter-Induced Peritonitis: A Case Report and Literature Analysis

“…Possibly soil contamination and unsterile techniques could explain relapsed infection in these cases, and thus catheter required removal. Of the 15 reported instances of R. radiobacter -induced peritonitis, six successfully kept the peritoneal catheter intact and resumed PD [ 8 , 13 , 16 , 17 , 20 , 21 ]. Our case adds to this complicated organism’s successful treatment of peritonitis.…”

“…Other antibiotics that have been effective include piperacillin-tazobactam, meropenem, and ciprofloxacin. However, it can be argued that in cases where catheter removal was not required, ceftazidime was the most used antibiotic and thus can be recommended as a treatment choice [ 13 , 16 , 17 , 21 ]. Three weeks of duration were pursued in a few cases because of the risk of catheter removal.…”

Opportunistic Bacteria Isolated from Trypauchen Vagina Fish that Infected with Protozoan from Iraq Marine Water

“…organisms that cause the death and disease of many fish are widely distributed in water (Al-Shemmari, 2017). Rhizobium radiobacter is originally characterised as an endo fungal bacterium, an uncommon opportunistic pathogen present in soil as an aerobic gram-negative belonging the Agrobacterium genus (Guo et al, 2017;Marta et al, 2011). Furthermore, A. hydrophila has been recorded in three marine fish species from the North West Arabian Gulf, Iraq (Al-Maleky and Hanafi ,2013 ).…”

Rhizobium radiobacter peritonitis in a peritoneal dialysis patient: Case presentation and review of the literature

“…2,7 The catheter preservation rate has increased from 33% (4 of 12 cases) in the 1990s to 2000s 1,6-13 to 67% (four of six cases) in the 2010s. [2][3][4][5]14 One reason for this improvement may be the use of fluoroquinolone antibiotics. In a previous report, Alnor et al suggested that ciprofloxacin might be the drug of choice.…”

“…Besides fluoroquinolones, this pathogen is usually sensistive to aminoglycosides, third-generation cephalosporins, cephamycins, and carbapenems. 2,7 Among the reported cases of R. radiobacter peritonitis, a combination of two antibiotics, which the bacterium was possibly sensitive to, was administered in six cases, [10][11][12][13][14] and catheter was preserved in five of the six cases [11][12][13][14] (Table 1). In case of peritonitis due to refractory bacteria, a combination therapy of two sensitive antibiotics may be effective.…”
