Bacterial outer membrane vesicle ( OMV ) -mediated delivery of proteins to host cells is an important mechanism of host-pathogen communication . Emerging evidence suggests that OMVs contain differentially packaged short RNAs ( sRNAs ) with the potential to target host mRNA function and/or stability . In this study , we... | Pseudomonas aeruginosa is a gram-negative , opportunistic pathogen that accounts for about 10% of all hospital-acquired infections in the US and primarily infects immunocompromised hosts , including patients with chronic obstructive pulmonary disease and cystic fibrosis .

However , it is notoriously difficult to study in a living organism . We have thus developed a new genetic tool that allows for the inducible generation of aneuploidy in the fruit fly Drosophila ... | [
