Exploitation of Drosophila Infection Models to Evaluate Antibacterial Efficacy of Phages
Nonmammalian infection models have been exploited to understand the various aspects of host-pathogen interactions and also provided innovative research platforms for identification of virulence factors, screening for antimicrobial hits, and evaluation of antimicroial efficacy. Here we describe a relatively straightforward protocol to assess the antibacterial efficacy of bacteriophages (phages) toward the opportunistic human pathogen, Pseudomonas aeruginosa, based on the systemic infection model using the fruit fly, Drosophila melanogaster. Since phages, unlike antibacterial chemicals, can be easily and sensitively enumerated by simple assays, it is also possible to address the pharmacokinetic properties of administered phages even in this small-scale infection model.
