Abstract:
Proteus organisms are rare causes of osteomyelitis. Vertebral osteomyelitis caused by this organism has only been reported in 21 cases over the last 75 years. Although Staphylococcus aureus is the most common cause of vertebral osteomyelitis, rare causes such as P. mirabilis may need to be considered in the context of recent urinary tract infection or urological surgery. Therefore biopsy should be undertaken to establish the causative organism and determine appropriate antibiotic susceptibility.
Insights
Proteus mirabilis is a rare cause of vertebral osteomyelitis, with only 21 reported cases in 75 years. Consider this organism in patients with recent urinary tract infections or urological surgery.
Area of Science:
- Infectious Diseases
- Microbiology
- Orthopedics
Background:
- Osteomyelitis, particularly vertebral osteomyelitis, is most commonly caused by Staphylococcus aureus.
- Proteus species are infrequent pathogens in bone infections.
Observation:
- Vertebral osteomyelitis attributed to Proteus organisms is exceptionally rare, with limited case reports over several decades.
- This specific bacterial cause is noted in only 21 instances within the last 75 years.
Findings:
- Proteus mirabilis should be considered as a potential causative agent for vertebral osteomyelitis.
- Its occurrence may be linked to recent urinary tract infections or prior urological procedures.
Implications:
- Diagnosis requires biopsy to identify the specific pathogen, Proteus mirabilis.
- Antimicrobial susceptibility testing is crucial for effective treatment of Proteus-induced vertebral osteomyelitis.
