See our new @plospathogens paper with the Hinton Lab @jay_salsa on the role of the MacAB-TolC efflux pump during infection by invasive #Salmonella isolates from Africa. doi.org/10.1371/journa…

Whole genome analysis of all sequenced African #iNTS isolates by @yan_salsa @NWenner and @implosian identified several variants of MacAB associated with each lineage.

We showed these MacAB variants change resistance to the antimicrobial peptide C18G and alter #Salmonella replication in macrophages.
These MacAB variants also alter relative fitness during competitive infections in the gut and in systemic sites.
