Lactobacillus Plantarum fights off Serratia marcescens and Pseudomonas aeruginosa

  • Serratia marcescens and Pseudomonas aeruginosa infection was more in axenic flies.
  • Infections were reduced when treated with Lactobacillus Plantarum.
  • quotidian replenishment - need to replenish microbial daily
  • If Lactobacillus is important, then why is it not maintained:
    • Dmel gets rids its gut of most microbes to minimize the risk of acquiring and maintaining potential pathogens.
    • The microbiome may compete with its Drosophila host for nutrients in the gut.
  • Our evidence indicates that Drosophila seeds its food with commensal organisms by depositing fecal matter on its food source on which the bacteria grow.

Propionic acid promotes larval survival

Propionic acid promotes larval survival (in low-nutrient food i.e. low yeast). Propionic acid is detected by Laravel chemoreceptors Or30a and Or94b. This propionic acid activity works on Dmel, but not on D. suzukii. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5660182/#:~:text=Propionic%20acid%20in%20the%20culture,medium%20(6.5%25%20yeast).

Forward & reverse genetics

Forward genetics: Start the research with an organism (eg. diseased or natural mutant) and then work backward to discover the genetic basis for it.  Reverse genetics, where specific genes are modified or manipulated to study their effects on a phenotype.
