Methicillin-Resistant Staphylococcus aureus has Phenotypic Variation in mecA Expression that Alters Antibiotic Sensitivity

Dongzhu Ma, Rekha Arya, Beth A. Knapick…·Kenneth L. Urish

This study shows that MRSA can exhibit antibiotic sensitivity due to reduced mecA expression and altered PBP2a levels in certain environments, suggesting new therapeutic targets.

Microbiota and metabolic adaptation shape Staphylococcus aureus virulence and antimicrobial resistance during intestinal colonization

Chunyi Zhou, Miranda B. Pawline, Alejandro Pironti…·Bo Shopsin

This study shows that gut microbiota depletion allows MRSA to adapt through genetic changes that enhance colonization fitness but reduce antimicrobial resistance and virulence.
