Staphylococcus epidermidis Genomic Plasticity Modulates Horizontal Gene Transfer

My Tran, Angel J Hernandez Viera, Jessica Ann Rosu…·Charlie Y. Mo

This study shows that Staphylococcus epidermidis rapidly deletes anti-MGE defense regions, increasing HGT, with environmental conditions influencing the balance between defense and genetic novelty.

Bacteriophage infection drives loss of β-lactam resistance in methicillin-resistant Staphylococcus aureus

My Tran, Angel J Hernandez Viera, Patricia Q. Tran…·Charlie Y. Mo

This study shows that phage infection reduces β-lactam resistance and virulence in MRSA by altering gene expression and genetic profiles.
