ABSTRACT
Significant attention has been recently paid to the two big issues in the 21st century molecular microbiology: antibiotic resistance and human microbiome, which urges new antibacterial strategies to minimize the evolution of resistance and to selectively control a subset of microbes in the human body. To meet these needs as well as the current requirements in the drug development, we have been focusing on 1)searching for side activities of the approved drugs (i.e. drug repositioning, DR) and 2)engineering phages and phage proteins (i.e. synthetic phage engineering), which has been greatly facilitated by the small scale live animal infection using Drosophila. Despite the physiological divergence between humans and insects, the modeling of infections caused by bacterial pathogens is deemed possible using Drosophila, based on the two (i.e. systemic and local) well established infection models: the systemic infection primarily caused by injecting bacteria into the dorsal thorax of flies mimics the acute infection, whereas the local/epithelial infection instigated by feeding flies with bacteria into the gut mimics the chronic or persistent infection. Topics discussed will include the up‐to‐date information on Drosophila infection models and brief reviews on our previous studies on identification of novel virulence genes, verification of antibacterial efficacy of therapeutic phages in vivo and a high through put screen for selective antibacterials with the focus on two new DR candidates (C‐3 and C‐ 83), which will be repurposed to new selective antibacterials to treat infections caused by methicillin‐resistant S. aureus (MRSA) and Vibrio cholerae.
