Rare case of Ureaplasma parvum septic arthritis in an immunocompetent patient

Area of Science:

• Microbiology
• Infectious Diseases
• Genomics

Background:

• The Mycoplasmatacea family includes Mycoplasma and Ureaplasma genera.
• Ureaplasma parvum commonly colonizes the human urogenital tract.
• Ureaplasma species are known pathogens in urogenital infections, but rarely implicated in native joint infections.

Observation:

• A rare case of septic arthritis in a native right knee is presented.
• The infection was caused by Ureaplasma parvum.
• Diagnosis was achieved through next-generation sequencing of microbial cell-free DNA and confirmed by PCR assays.

Findings:

• Next-generation sequencing identified Ureaplasma parvum as the causative agent of native knee septic arthritis.
• This case highlights a rare presentation of Ureaplasma parvum infection.
• The study incorporates a literature review of prior cases, antibiotic management, and antimicrobial resistance patterns.

Implications:

• This case broadens the understanding of Ureaplasma parvum pathogenicity beyond urogenital infections.
• Advanced diagnostic techniques like next-generation sequencing are crucial for identifying rare pathogens.
• The findings contribute to the clinical knowledge base for managing Ureaplasma septic arthritis, including appropriate antibiotic strategies.
