Pseudomonas sp. group Ve-2 bacterial peritonitis in a patient on continuous ambulatory peritoneal dialysis

Abstract

Pseudomonas sp. group Ve-2 peritonitis occurred in a patient on continuous ambulatory peritoneal dialysis who had recently completed intraperitoneal cephalosporin therapy for culture-negative peritonitis. This is the second reported case of peritonitis in this population of patients due to this unusual organism, which is usually resistant to most cephalosporin antibiotics.

Flavimonas oryzihabitans (Pseudomonas oryzihabitans; CDC group Ve-2): an emerging pathogen in peritonitis related to continuous ambulatory peritoneal dialysis?

“…Prior use of cephalosporins is likely to select for colonization with F. oryzihabitans. As in the other two recorded cases of peritonitis caused by this organism (1,12), our patient had had a previous course of a cephalosporin, though the original source of the organism remains obscure. Our patient had never been in the vicinity of rice paddies.…”

“…Hemolysis does not occur on 5% horse blood agar, and there is no fluorescence on King's medium B. The organism is susceptible to several antibiotics-ampicillin, carbenicillin, cefotaxime, chloramphenicol, colistin, erythromycin, gentamicin, neomycin, and tetracycline (6)-but is resistant to the cephalosporins (1,2,11).…”

Non catheter‐related bacteremia caused by Pseudomonas oryzihabitans in a patient undergoing hemodialysis

“…14 Cases of P. oryzihabitans peritonitis have been reported in patients undergoing long-term peritoneal dialysis. [15][16][17][18][19][20] Only one patient who underwent CAPD needed catheter removal, because of coinfection with a candida species. 16 The isolation of this environmental organism in clinical samples should be interpreted according to clinical data, as it can be the cause of disease especially in those with indwelling devices such as peritoneal catheters.…”

Postoperative infant septicemia caused by Pseudomonas luteola (CDC group Ve-1) and Pseudomonas oryzihabitans (CDC group Ve-2)

“…It is notable that, in the present case, the infant had been given perioperative cefazolin. This antibiotic has a spectrum of activity very similar to that of cephalothin with which patients in several other reported cases had been treated before the onset of infection (1,3,20).…”

“…Newsl. 4:87, 1982) and peritonitis (1,3,20), usually in association with indwelling catheters or prostheses. However, this is apparently the first report of the simultaneous isolation of both species from the blood of a septicemic patient.…”
