SMOX and infection: As melanization mutant flies are already succumbing fast to the ingestion of PAO1 (Figs 3C and S3D), making it difficult to ascertain precisely the contribution of the secondary infection to the lethality of these PAO1-latently infected flies, we decided to attenuate the virulence of ingested PAO1 by adding levofloxacin instead of gentamicin to a sucrose solution after two days of PAO1 ingestion.
