Summary
This study reports a rare case of prosthetic knee infection caused by Mycobacterium mageritense. Prompt treatment involving hardware removal and antimicrobials led to a successful outcome in this prosthetic joint infection.
Area of Science:
- Infectious Diseases
- Orthopedic Surgery
- Microbiology
Background:
- Prosthetic joint infections (PJI) affect up to 2% of arthroplasties, typically caused by bacteria.
- Mycobacterial species, though infrequent, pose challenges in PJI due to biofilm formation and antimicrobial resistance.
- Mycobacterium mageritense is a rapidly growing mycobacterium rarely implicated in device-related infections.
Observation:
- A case of prosthetic knee infection caused by Mycobacterium mageritense is presented.
- Mycobacterium mageritense is a rapidly growing mycobacterium rarely implicated in surgical or device-related infections.
Findings:
- The patient with prosthetic knee infection due to M. mageritense underwent successful treatment.
- Treatment involved hardware removal, antimicrobial therapy, and prosthetic knee reimplantation.
Implications:
- This case expands the known spectrum of pathogens causing prosthetic joint infections.
- Mycobacterium mageritense should be considered in the differential diagnosis of recalcitrant prosthetic joint infections.

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
