Methicillin-resistant Staphylococcus aureus colonization in veterinary personnel

Area of Science:

• Veterinary Medicine
• Infectious Diseases
• Public Health

Background:

• Methicillin-resistant Staphylococcus aureus (MRSA) is a significant pathogen in both human and animal health.
• Understanding MRSA colonization in veterinary professionals is crucial for infection control.

Purpose of the Study:

• To determine the prevalence of MRSA nasal colonization among attendees at an international veterinary conference.
• To identify risk factors associated with MRSA colonization in this population.

Main Methods:

• Nasal swabs were collected from conference attendees.
• MRSA presence was confirmed using standard microbiological techniques.
• Pulsed-field gel electrophoresis (PFGE) was employed to analyze MRSA strains.

Main Results:

• Overall MRSA colonization rate was 6.5% (27/417).
• Colonization was significantly higher in large-animal personnel (15.6%) compared to small-animal personnel (4.4%).
• Large-animal practice was the only significant risk factor (OR 2.9).
• Two predominant MRSA clones were identified, with distinct distributions related to animal contact and geographic origin.

Conclusions:

• MRSA colonization is prevalent in veterinary professionals, especially those in large-animal practice.
• Veterinary professionals, particularly those working with large animals, may face an occupational risk of MRSA colonization.
• Further research into MRSA transmission dynamics in veterinary settings is warranted.
