Effect of multicopy hha on serovar Typhimurium hilA::Tn5lacZY expression. Strains were grown statically in LB broth to an OD600 of ≈0.4 before assaying β-galactosidase activity from the hilA::Tn5lacZY reporter. Strain BJ70 carries a chromosomal hilA::Tn5lacZY reporter, while pLS31 is a low-copy-number hilA::Tn5lacZY reporter plasmid (50). Salmonella SL1344 is the wild-type virulent strain.
