Pyogenic Liver Abscess Caused by Acinetobacter lwoffii: A Case Report

Area of Science:

• Microbiology
• Infectious Diseases
• Hepatology

Background:

• Acinetobacter lwoffii is a gram-negative, aerobic, non-fermenter bacillus.
• It is recognized as an emerging pathogen, particularly in nosocomial infections and immunocompromised individuals, often following Acinetobacter baumannii.
• Liver abscesses are serious infections requiring prompt diagnosis and treatment.

Observation:

• This report details a unique case of a pyogenic liver abscess.
• The abscess was community-acquired, meaning it was not contracted in a hospital setting.
• The causative agent identified was Acinetobacter lwoffii.

Findings:

• Acinetobacter lwoffii was identified as the sole pathogen responsible for the pyogenic liver abscess.
• The patient had diabetes mellitus, a condition often associated with increased susceptibility to infections.
• This represents a rare instance of community-acquired liver abscess attributed to Acinetobacter lwoffii.

Implications:

• The findings suggest Acinetobacter lwoffii may be an underrecognized cause of community-acquired infections, including liver abscesses.
• Clinicians should consider Acinetobacter lwoffii in the differential diagnosis of liver abscesses, especially in diabetic patients.
• Further research is warranted to understand the epidemiology and clinical spectrum of Acinetobacter lwoffii infections.
