The nonredundant transposon insertion mutant library of P. aeruginosa strain PA14, designated as PA14NR Set, facilitates analysis of gene functionality in numerous processes. Presented here is a protocol to generate high-quality copies of the PA14NR Set mutant library.

It allows browsing the data, criteria-based selection, averaging, localization of measurements within a 3D volume of vasculature and exporting the data.
In Vivo Investigation of Antimicrobial Blue Light Therapy for Multidrug-resistant Acinetobacter baumannii Burn Infections Using Bioluminescence Imaging Yucheng Wang1,2,3, Olivia D. Harrington1, Ying Wang1, Clinton K. Murray4, Michael R. Hamblin1, Tianhong Dai1 1Wellman Center for Photomedicine, Massachusetts General Hospital, Harvard Medical School, 2Department of Medical Oncology, Beijing Institute of Translational Medicine, Chinese Academy of Sciences, 3Cancer Center, Aviation General Hospital, Beijing, 4Infectious Disease Service, Brooke Army Medical Center Infections caused by multidrug-resistant (MDR) bacterial strains have emerged as a serious threat to public health, necessitating the development of alternative therapeutics. We present a protocol to evaluate the effectiveness of antimicrobial blue light (aBL) therapy for MDR Acinetobacter baumannii infections in mouse burns by using bioluminescence imaging.
