“…However, taxa such as Acinetobacter, Burkholderia Pseudomonas, Mycobacterium, and Staphylococcus have been described previously as causative agents of infections or related to pyrogenic reactions during dialysis sessions. [32][33][34][35][36][37][38] From a laboratory point of view, standard protocols are available to address the quality of hemodialysis water. 7,8,36,37,39 However, in our setting, current monitoring of bacterial communities in hemodialysis water is usually restricted to the reporting of total viable count or the detection of specific groups of bacteria (Enterobacteriaceae and Pseudomonas) using culturing of water samples on Blood agar or MuellerHinton agar with a short incubation time (16-24 hours) at 37°C.…”

It seems that poorly designed water treatment systems (multiple 90° turns), use of PvC for a long time (8-22 years, Table 1), and lack of proper maintenance are other problems in our settings that we must tackle to control microbial contamination of hemodialysis water.…”

Microbiological control of hemodialysis fluid is important for the prevention of hemodialysis-associated illness. Bacterial populations inhabiting a distribution system for hemodialysis water were studied over a 4 month period in five hospitals (one in Tehran, and the others at Alborz). All the samples from the four hospitals at Alborz had colony counts of ≥100 CFU/ml, which at different points of sampling were higher than the maximum recommended values. A total of 80 samples taken at different points in each hospital's hemodialysis distribution system were collected, and 229 planktonic bacteria isolated on R2A medium. No growth was detected by culturing the samples on Blood agar or Mueller-Hinton agar, according to routine procedures currently used in the five hospitals. A representative of isolates from each of 45 different morphotypes were identified using 16S RNA sequencing. A diverse bacterial community, containing predominantly gram-positive members of Kocuria, Arthrobacter and Staphylococcus and Mycobacterium, was detected. Bacteria from the genera Acinetobacter, Burkholderia, Halomonas, Herbaspirillum, Pseudomonas, and Sphingomonas were identified, which has been described in the build-up of biofilms. Some of the species reported here may represent a health risk to patients receiving hemodialysis treatment. In conclusion, it is recommended that standard protocols for evaluation of microbial contamination be used for regular monitoring and identification of culturable bacteria.

“…Pseudomonas oryzihabitans is a potential nosocomial pathogen causing various infections, particularly cutaneous infections; due to lack of significant information about pathogenicity, virulence factor, and few clinical reports of this bacterium's infections, the pathogenicity of P oryzihabitans is still a puzzle for the scientific community. This bacterium is not human normal‐flora and numerous reports suggested that the bacterium's transition is through environment …”

“…P oryzihabitans is a saprophytic bacteruim that lives freely in environmental resources such as soil, rice paddles, medical equipment, or hospital wash‐hand basin . 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 .…”

Hidradenitis suppurativa (HS) is one of the neglected chronic inflammatory disorders which has not efficient treatment. These patients were susceptible to various infectious diseases because of their changes in immuneresponse. Also, HS pathogenesis remains unclear and its report can create novel insight into mechanism and pathogenesis of this infection. Moreover, given that different susceptibility patterns of Pseudomonas spp this species should be identified to the species level; molecular methods are rapid, inexpensive, and reliable method for identification of infectious agents to the species level and appropriate treatment of infections.

“…Since the 1970s, when the first case of bacteremia in a neurosurgical patient with extradural cerebral hemorrhage secondary to P. oryzihabitans was reported, other researchers have identified the pathogen in patients with cancer, end-stage cirrhosis, sickle cell disease, and community-acquired urinary tract infections [5, 6]. 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].…”

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

et al. 2017

View full text Add to dashboard Cite

Background Pseudomonas oryzihabitans is a Pseudomonas bacterial organism rarely implicated in human infections. The bacterium has been isolated in a few reported cases of neurosurgical infections and patients with end-stage cirrhosis, sickle cell disease, and community-acquired urinary tract infections. Limited information exists in developing countries, however, because of the lack of advanced microbiological tools for identification and characterization of this bacterium. This case report describes the isolation of a rare Pseudomonas bacterium in a patient presenting with sepsis and skin infection.Case presentationA 1-year-old girl was presented to a hospital in the northeastern part of Ghana with a 1-week history of pustular rashes on her scalp and neck, which occasionally ruptured, along with discharge of yellowish purulent fluid. The child is of Mole-Dagbon ethnicity and hails from the northern part of Ghana. Pseudomonas oryzihabitans was identified in the patient’s blood culture using the 16S ribosomal deoxyribonucleic acid sequencing technique. The rash on the patient’s scalp and skin resolved after continuous treatment with gentamicin while her condition improved clinically.ConclusionsThis finding suggests the potential of this bacterium to cause disease in unsuspected situations and emphasizes the need to have evidence for the use of the appropriate antibiotic in clinical settings, particularly in rural settings in Africa. It also brings to the fore the unreliability of conventional methods for identification of Pseudomonas bacteria in clinical samples and thus supports the use of 16S ribosomal deoxyribonucleic acid in making the diagnosis.
