Nonsynonymous mutations in fepR are associated with Listeria adaptation to low concentrations of benzalkonium chloride, but not increased survival in use level concentrations of benzalkonium chloride.

The paper identifies nonsynonymous fepR mutations in Listeria strains adapted to low benzalkonium chloride concentrations but finds no increased survival at use-level concentrations.

The Typhoid Toxin Produced by the Nontyphoidal Salmonella Serovar Javiana Can Utilize Multiple Binding Subunits, which Compete for Inclusion in the Holotoxin

This study shows that S. Javiana's typhoid toxin uses multiple binding subunits that compete for inclusion in the holotoxin, enhancing toxin versatility.
