Porphyromonas asaccharolytica liver abscess

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Case Reports

Background:

• Porphyromonas species are black pigmented, Gram-negative anaerobic bacteria.
• These bacteria are recognized pathogens in various infections, including CNS, dental, pulmonary, and genitourinary systems, as well as bacteremia.

Purpose of the Study:

• To report an extremely rare case of liver abscess.
• To highlight the causative agent, Porphyromonas asaccharolytica, in this specific clinical presentation.

Main Methods:

• Case identification and clinical data review.
• Microbiological analysis of the clinical specimen.
• Identification of the causative bacterial species.

Main Results:

• A liver abscess was diagnosed.
• Porphyromonas asaccharolytica was isolated as the causative agent.
• This represents the first reported instance of Porphyromonas asaccharolytica causing a liver abscess.

Conclusions:

• Porphyromonas asaccharolytica can be an etiological agent of liver abscesses.
• This case expands the spectrum of known Porphyromonas-associated infections.
• Clinicians should consider Porphyromonas species in the differential diagnosis of liver abscesses, particularly in polymicrobial infections.
