Pseudomonas stutzeri: an unusual cause of calcaneal Pseudomonas osteomyelitis

Prosthetic knee septic arthritis due to Pseudomonas stutzeri

Prosthetic joint infection is usually caused by Staphylococcus aureus, coagulase-negative staphylococci and, less commonly, by Gram-negative bacilli and anaerobes. A case of prosthetic joint infection due to Pseudomonas stutzeri in a 73-year-old female with acute promyelocytic leukemia is presented, and the pertinent literature is reviewed. Although the patient had prolonged neutropenia, the infection was successfully treated with antibiotics and without artificial joint replacement.

Pseudomonas stutzeri knee arthritis in a child: case report and review

We report a child with Pseudomonas stutzeri-associated right knee arthritis following knife puncture wound. Only four children with P. stutzeri-associated infections have been reported in the English literature in the last 40 years of whom one suffered from calcaneal osteomyelitis caused by this pathogen. In both cases, the suggested mechanism of the infection was local rather than bacterium invasion.

Biology of Pseudomonas stutzeri

Pseudomonas stutzeri is a nonfluorescent denitrifying bacterium widely distributed in the environment, and it has also been isolated as an opportunistic pathogen from humans. Over the past 15 years, much progress has been made in elucidating the taxonomy of this diverse taxonomical group, demonstrating the clonality of its populations. The species has received much attention because of its particular metabolic properties: it has been proposed as a model organism for denitrification studies; many strains have natural transformation properties, making it relevant for study of the transfer of genes in the environment; several strains are able to fix dinitrogen; and others participate in the degradation of pollutants or interact with toxic metals. This review considers the history of the discovery, nomenclatural changes, and early studies, together with the relevant biological and ecological properties, of P. stutzeri.

Nosocomially acquired Pseudomonas stutzeri brain abscess in a child: case report and review

Pseudomonas stutzeri is a rare cause of nosocomial infection. We report a pediatric case of nosocomially acquired P. stutzeri brain abscess after subdural grid implantation before surgery for refractory epilepsy and review the literature.

Pseudomonas stutzeri infection. A review of hospital isolates and a review of the literature

Pseudomonas stutzeri is uncommonly isolated from patients and rarely causes disease. Clinical isolates of P. stutzeri from a university hospital were reviewed over a 16-year period. In the hospital review, only three patients were identified with P. stutzeri infection, and in only one of these was the organism present as the sole isolate. A review of the literature shows that P. stutzeri is most frequently isolated from blood, wounds, the respiratory tract, and urine. Patients with P. stutzeri infections often have serious underlying disease but generally respond to treatment with antibiotics including the aminoglycosides, the antipseudomonal penicillins, trimethoprim-sulfamethoxazole, and the third-generation cephalosporins.

Puncture wound osteochondritis of the foot caused by CDC group Vd

A case of puncture wound osteochondritis of the foot caused by CDC group Vd is presented because of the unusual nature of the infecting organism. This organism may be confused with Pseudomonas aeruginosa, the usual pathogen responsible for this type of infection, but does not have a similar antimicrobial susceptibility profile. For this reason, it is important to obtain appropriate culture specimens and to identify and test the susceptibility of bacterial isolates from cases of puncture wound-associated osteochondritis so that optimal therapeutic regimens can be determined.
