Dose-limiting nephrotoxicity remains the Achilles' heel of polymyxin B and polymyxin E (also known as colistin), which are important last-line antibiotics used against infections caused by MDR Gram-negative 'superbugs'. An understanding of the mechanisms of nephrotoxicity, including renal tissue distribution, is crucial for the development of safer polymyxin lipopeptide antibiotics. This is the first study to visualize the kidney distribution of polymyxin B using a mouse nephrotoxicity model and in situ immunostaining of kidney sections.
