Antibacterial Efficacy ofBacteriophages on aInfection Model.

Abstract

is a widespread pathogen that causes acute and chronic diseases in various organisms, including humans. Treating this antibiotic-resistant bacterium is challenging, so alternative or supplementary treatment strategies are desirable. Six novel bacteriophages specific towere isolated and classified into the genera,,, and a new, unnamed genera related to, and. Their genomes were annotated and further characterized. We used theinsect model to predict the efficacy of the phages in terms of their curative function on other organisms. Flies were chronically infected by feeding them bacteria and were subsequently treated with individual bacteriophages. The results of the Kaplan-Meier survival test revealed differences in phage efficacy and supported the hypothesis that the phages had a curative effect. These mentioned phages extended the flies' lifespan.
