Abstract:
Pseudomonas oryzihabitans is a saprophytic gram-negative microorganism usually found in damp environments, only occasionally responsible for human pathology. Infection mainly occurs in malnourished, immunocompromised individuals with indwelling catheters. There is no previous published record of infection after joint arthroplasty. To enhance the literature, in this article we report a patient with a Pseudomonas oryzihabitans infected total hip arthroplasty, and discuss the diagnosis and management of this unusual infection.
Insights
Pseudomonas oryzihabitans, a rare cause of infection, can affect individuals with compromised immunity. This report details the first known case of Pseudomonas oryzihabitans infection following total hip arthroplasty.
Area of Science:
- Microbiology
- Infectious Diseases
- Orthopedic Surgery
Background:
- Pseudomonas oryzihabitans is a gram-negative bacterium typically found in moist environments.
- It is an opportunistic pathogen, rarely causing human infections, primarily in immunocompromised individuals with medical devices.
- No prior documented cases of Pseudomonas oryzihabitans infection after joint arthroplasty exist.
Purpose of the Study:
- To report the first case of Pseudomonas oryzihabitans infection in a total hip arthroplasty.
- To discuss the diagnostic challenges and management strategies for this rare orthopedic infection.
Main Methods:
- Case report presentation.
- Literature review on Pseudomonas oryzihabitans infections and prosthetic joint infections.
Main Results:
- A patient with a total hip arthroplasty developed an infection caused by Pseudomonas oryzihabitans.
- The infection presented challenges in diagnosis and treatment due to its unusual nature.
Conclusions:
- Pseudomonas oryzihabitans should be considered in the differential diagnosis of prosthetic joint infections, especially in at-risk patients.
- Early diagnosis and appropriate management are crucial for successful outcomes in these rare cases.
