[7 cases of Staphylococcus lugdunensis infection]

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Medicine

Background:

• Staphylococci are common bacteria, with most species being coagulase-negative.
• The pathogenic potential of coagulase-negative staphylococci, including Staphylococcus lugdunensis, is not fully understood.
• Staphylococcus lugdunensis, named after Lyon, France, is a recently identified species.

Observation:

• This study presents seven cases of human infections caused by Staphylococcus lugdunensis.
• Infections occurred in patients with various underlying conditions, including diabetes, bladder tumors, cerebrovascular stroke, endocarditis, liver cirrhosis, and osteosarcoma.
• S. lugdunensis was isolated from diverse clinical samples such as conjunctival exudate, urine, blood cultures, and wound exudate.

Findings:

• Staphylococcus lugdunensis was identified as the causative agent in seven distinct human infections.
• The cases demonstrate a broad spectrum of clinical presentations associated with S. lugdunensis.
• This species can cause infections ranging from localized to systemic.

Implications:

• The findings expand the known clinical spectrum of diseases caused by Staphylococcus lugdunensis.
• This study underscores the importance of recognizing S. lugdunensis as a potential human pathogen.
• Further research is warranted to fully elucidate the pathogenicity and clinical significance of S. lugdunensis.
