Unusual bacterium, group Ve-2, causing peritonitis in a patient on continuous ambulatory peritoneal dialysis

Abstract

We report a case of peritonitis in a continuous ambulatory peritoneal dialysis patient with an unusual bacterium known as group Ve-2. This is the first reported case of peritonitis attributable to this organism and only the second well-documented case of infection with this organism in the English literature.

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)

“…Discussion. The normal habitat of P. luteola (Chryseomonas luteola) and P. oryzihabitans (Flavimonas oryzihabitans) is unclear, although they belong to a group of bacteria normally found in water, soil, and other damp environments (20). They are rare human pathogens, occasionally isolated from pus and wounds (10) and implicated in a handful of reported cases of septicemia (2,11,15,17,18; B. Shaw and V. Baselski, Clin.…”

“…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.…”

“…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).…”

AN INVESTIGATION OF A COLLECTION OF YELLOW‐PIGMENTED PSEUDOMONAS

“…Although often believed to be of no clinical signficance, VE-1 and VE-2 as well as P. paucimobilis have been suspected as causal organisms in different kinds of infections such as bacteremia (Pien 1977;Slotnick et al 1979;Southern & Kutscher 198 I), peritonitis in patients on peritoneal dialysis (Glupczynski et ul. 1984;Silver et al 1985), meningitis (Hajiroussou et al 1979), and leg ulcer (Peel et al 1979) and therefore should be recognized in the laboratory.…”
