Wound infections respond poorly to antibiotic therapy due to poor drug penetration and the presence of persister cells within biofilms. This study targets both of these obstacles by combining a novel aminoglycoside adjuvant with potent anti-persister activity with Sonotherapy. Sonotherapy is an ultrasound-mediated method to mechanically improve drug delivery. Palmitoleic acid, a novel aminoglycoside adjuvant, sensitized multiple gram positive pathogens to gentamicin. Combining this drug combination with Sonotherapy in vivo, improved treatment of a methicillin-resistant wound infection in diabetic mice.. Together, this data suggests that using a combined approach to target persister cells and improve drug penetration is a promising strategy to combatting recalcitrant wound infections. This data contains a prism file containing in vitro data (Fig. 1-4) and a separate prism file containing the in vivo data from the study (Fig. 5-6).
