What is the primary mode of MRSA transmission in humans and animals?
MRSA is transmitted by direct contact via hands or touching contaminated surfaces.
What types of animals are most commonly associated with MRSA infections?
Animals exposed to medical hospitals, with extensive wounds, prolonged hospitalisation, or immunosuppression.
What percentage of healthy individuals carry Staphylococcus aureus, including MRSA, in their nostrils?
About 30% of people carry Staphylococcus aureus in their nostrils.
What type of samples should be routinely tested for MRSA in animals?
Coagulase-positive Staphylococci isolates should be tested for oxacillin resistance.
What are common signs of MRSA in animals?
Non-healing wounds, surgical implants, pyoderma, or indwelling catheters.
What precautions should be taken when an MRSA-positive animal is admitted to a veterinary clinic?
The animal should be taken directly to a consulting room, and open wounds should be covered with dressings.
How should a veterinary clinic handle MRSA-positive patients during transportation?
The patient should be transported on a trolley to prevent contamination, and movement should be minimized.
What should staff wear when in direct contact with MRSA-positive animals?
Staff should wear gloves, plastic gowns, and face masks, and tie back long hair.
