This study shows that RNase HI deficiency in Salmonella enterica reduces virulence by altering gene expression and virulence-related phenotypes, suggesting it as a target for anti-virulence strategies.

When pyoverdine and elastase are both needed, a pvdS mutant outcompetes the lasR cheater in P. aeruginosa and averts population collapse; a cost-ratio model with quorum sensing explains this.
