Moraxella lacunata Subacute Osteomyelitis in a Child

Area of Science:

• Microbiology
• Pediatric Orthopedics
• Infectious Diseases

Background:

• Moraxella lacunata is a rare coccobacillus.
• Typically associated with ocular and upper respiratory tract infections.
• Potential affinity for bone and joint tissues is less understood.

Purpose of the Study:

• To report a rare case of pediatric osteomyelitis.
• To describe the presentation of Moraxella lacunata-induced bone infection.
• To highlight the diagnostic considerations for osteolytic lesions in children.

Main Methods:

• Case report of a pediatric patient.
• Clinical presentation and imaging findings.
• Microbiological identification of Moraxella lacunata.

Main Results:

• A child presented with subacute osteomyelitis of the patella.
• The infection was caused by Moraxella lacunata.
• Radiographic findings revealed an osteolytic bone lesion.

Conclusions:

• Moraxella lacunata can cause osteomyelitis, even in children.
• Osteolytic bone lesions in pediatric patients warrant consideration of rare pathogens.
• This case expands the known spectrum of Moraxella lacunata infections.
