Methicillin resistant Staphylococcus aureus carriage among guinea pigs raised as livestock in Ecuador

Antimicrobial resistance is a growing problem in human and veterinary medicine. Here we show that 6.25% of the guinea pigs studied in Ecuador, raised as livestock, carry methicillin resistant Staphylococcus aureus (MRSA) in the nasopharynx and therefore may potentially play a role in the transmission of MRSA in the Andean Region of South America.
