New pre-print in the lab! Beautiful work by Francisco Garcia-Rodriguez in collab with @Kamo_Valenzuela and @JuakiBernal : when macrophages are provided with specific nutrients, Salmonella can bypass its requirement of the T3SS to replicate, a process that occurs within the SCV

Happy to share our lastest story (with @HallezLab, @LBarquist, @CMichaux13) ! We show how host-relevant stress disrupts Fe-S cluster stability, tuning (p)ppGpp levels to control bacterial adaptation and trigger virulence. Read more here 👉
