Control of Klebsiella pneumoniae Infection in Mice by Using Dissolving Microarray Patches Containing Gentamicin

Using a murine model of bacterial infection, we demonstrate that gentamicin dissolving microarray patches, applied to murine ears, could control infection. Mice treated with microarray patches had reduced bacterial burden in the nasal-associated lymphoid tissue and lungs compared with their untreated counterparts. This proof of concept study represents the first published data on the delivery of the antibiotic gentamicin via dissolving microarray patches, resulting in the control of bacterial infection.
