Raoultella Ornithinolytica Diagnosed in a Neurointensive Patient. A Rare Case with Recovery without Antibiotics

Area of Science:

• Infectious Diseases
• Microbiology
• Clinical Case Reports

Background:

• Raoultella ornithinolytica is an opportunistic pathogen rarely causing infections.
• Infections typically occur in patients with severe comorbidities like malignancies or chronic diseases.
• Standard treatment involves antibiotics, often broad-spectrum.

Observation:

• A neuro-intensive care unit patient presented with R. ornithinolytica infection.
• This patient lacked significant underlying malignancies or chronic diseases.
• The patient was concurrently colonized with Pseudomonas aeruginosa.

Findings:

• The patient experienced a spontaneous resolution of R. ornithinolytica infection.
• Recovery occurred without the administration of any antibiotic therapy.
• The clinical course suggests potential self-limiting mechanisms for this infection.

Implications:

• This case challenges the necessity of antibiotic treatment for all R. ornithinolytica infections.
• It highlights the possibility of spontaneous resolution in select patient populations.
• Further research is warranted to understand the host-pathogen interactions and immune responses involved.
