Frequency of resistance to methicillin and other antimicrobial agents among Staphylococcus aureus strains isolated from pigs and their human handlers in Trinidad

摘要

Annually, methicillin-resistant Staphylococcus aureus (MRSA) is responsible for over 2 million nosocomial infections worldwide (1–3). In the United States alone, MRSA is the tenth leading cause of death in humans, as well as the most common antimicrobial drug-resistant pathogen in hospitals and healthcare facilities, whereas in the United Kingdom it was estimated that MRSA was responsible for deaths of over 5,000 per year (4). These infections in humans include food poisoning, soft tissue infection, purulent pneumonia, upper respiratory infections, subcutaneous abscesses, toxic shock syndrome, post-operative infections and bacteremia (5–7).
