Methicillin-Resistant Staphylococcus aureus in the Oral Cavity: Implications for Antibiotic Prophylaxis and...

Area of Science:

• Microbiology
• Infectious Diseases
• Oral Health

Background:

• The oral cavity hosts diverse bacteria, acting as a reservoir for antibiotic resistance genes.
• Bacterial biofilms in the mouth facilitate horizontal gene transfer, promoting antibiotic resistance.
• High carriage rates of methicillin-resistant Staphylococcus aureus (MRSA) in the oral cavity have been reported.

Purpose of the Study:

• To highlight the role of the oral cavity as a reservoir for antibiotic resistance determinants.
• To discuss the implications of increasing oral MRSA carriage rates.
• To examine how antibiotic prophylaxis may influence MRSA epidemiology in the mouth.

Main Methods:

• Review of recent reports on MRSA carriage in the oral cavity.
• Analysis of the role of biofilms and horizontal gene transfer in oral antibiotic resistance.
• Consideration of the impact of antibiotic prophylaxis on MRSA prevalence.

Main Results:

• The oral microbiome can harbor antibiotic resistance genes.
• Oral biofilms promote the spread of resistance genes via horizontal gene transfer.
• Increased oral MRSA carriage rates are a growing concern.

Conclusions:

• The oral cavity's role in antibiotic resistance and MRSA epidemiology requires attention.
• Understanding oral MRSA carriage is crucial for developing effective prevention strategies.
• Clinical practices and carriage study methodologies may need adaptation in light of changing MRSA epidemiology.
