Outbreak ofPseudomonas OryzihabitansPseudobacteremia Related to Contaminated Equipment in an Emergency Room of a Tertiary Hospital in Korea

Abstract

Pseudomonas oryzihabitans is frequently found in various sites within hospital settings, including sink drains and respiratory therapy equipment. Although it rarely causes human infections, P. oryzihabitans has recently been considered a potential nosocomial pathogen, especially in immunocompromised hosts. We report our experience of an outbreak of P. oryzihabitans pseudobacteremia, presumably due to faulty aseptic preparation of a saline gauze canister.

Pseudomonas oryzihabitans sepsis in a 1-year-old child with multiple skin rashes: a case report

“…P. oryzihabitans is a rare bacterial isolate that has been linked to meningitis, endocarditis, diabetes mellitus, and infection with other organisms, especially in immunocompromised individuals [4, 15]. The pathogenicity of P. oryzihabitans is still a subject of debate in the scientific community, hence the need for adequate information to enable clinicians and public health practitioners to manage episodes associated with this pathogen.…”

“…The bacterium is gram-negative and oxidase-negative with typical yellow-pigmented colonies visualized on agar media. It is thought to survive in moist environments, especially rice paddies, although some researchers have cultured cases from inhalational therapy equipment and hospital sinks [3, 4]. The organism has rarely been implicated as pathogenic in humans and often is not given serious attention in clinical practice.…”

“…P. oryzihabitans, unlike the other forms of Pseudomonas bacteria (for example, Pseudomonas aeruginosa , and Burkholderia cepacia ) is susceptible to quinolones, carbapenems, β-lactamase inhibitor drugs, and trimethoprim/sulfamethoxazole [4, 7]. Treatment algorithms for managing P. oryzihabitans are not available in Ghana and many other developing countries, particularly those in sub-Saharan Africa.…”

The first report of Pseudomonas oryzihabitansin infection in a patient with hidradenitis suppurativa

“…Primarily, P oryzihabitants was not referred to as a pathogenic bacterium until 1970s when the first case of bacteremia was reported by Hellou et al Nowadays, this bacterium is known as a pathogenic bacterium isolated from human infections such as wound and soft tissue infections, septicemia, hip infection, prosthetic valve endocarditis, peritonitis, meningitis, abscesses, pneumonia, and urinary tract infections . According to previous reports, P oryzihabitans can be considered as a nosocomial agent associating with several outbreaks . Given that literatures, immune‐disorder patients are exposed to be infected with P oryzihabitans more than the others …”

Pseudomonas oryzihabitans bacteremia in a child with peripheral T‐cell lymphoma after allogeneic bone marrow transplantation

“…Pseudomonas oryzihabitans , previously known as Chromobacterium typhiflavum or Flavimonas , is a glucose non‐fermentative, Gram‐negative, rod‐shaped bacterium. P. oryzihabitans has been detected in moist environments in respiratory therapy equipment and hospital sinks . Recently, P. oryzihabitans has emerged as an opportunistic pathogen in immunocompromised hosts and has been implicated in serious infections such as bacteremia, meningitis, septicemia, endophthalmitis, endocarditis, peritonitis, urinary tract infection, soft‐tissue infection, and periprosthetic joint infection .…”
