The treatment of methicillin-resistant Staphylococcus aureus (MRSA)-induced pneumonia with antibiotics alone poses considerable challenges. To address these challenges, low-frequency ultrasound (LFU) emerges as a promising approach. In this study, mouse model was established through intratracheal injection MRSA to investigate the therapeutic efficacy LFU in combination antibiotics. Minimal inhibitory concentration assessed, and distribution lung plasma determined using liquid chromatography...

Abstract Hydrogels, with their high water content and flexible nature, are a promising class of medical dressings for combating bacterial wound infections. However, development has been hindered by low sterilization efficiency.
