Clinical Findings of Listeria monocytogenes Infections with a Special Focus on Bone Localizations

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Medicine

Background:

• Listeria monocytogenes is a Gram-positive bacterium found in soil and water.
• Infection occurs via ingestion of contaminated food, leading to listeriosis outbreaks.
• Common clinical syndromes include sepsis, meningitis, and rhombencephalitis, especially in immunocompromised individuals.

Purpose of the Study:

• To describe clinical findings of invasive listeriosis.
• To focus on the diagnosis, clinical management, and treatment of bone and vertebral infections caused by L. monocytogenes.

Main Methods:

• Clinical case review.
• Analysis of diagnostic approaches.
• Evaluation of treatment strategies for invasive listeriosis.

Main Results:

• L. monocytogenes systemic infections can arise from gastrointestinal tract penetration or hematogenous spread.
• Bone and joint infections are rare, often associated with prosthetic materials.
• Detailed clinical findings for invasive listeriosis, including bone/vertebral infections, are presented.

Conclusions:

• Invasive listeriosis, though rare, can manifest as severe bone and joint infections.
• Early diagnosis and appropriate management are crucial for favorable outcomes.
• This study highlights key aspects of managing L. monocytogenes bone and vertebral infections.
