S. Typhimurium growth curves. Bacteria were grown in LB-Miller broth at 37 °C, with (closed circles) or without (open circles) aeration. Bacterial growth was determined by OD₆₀₀ (a) or culturable bacterial numbers (b). Arrowheads and dashed vertical lines indicate the time points at which aer-LL and μaer-ST bacteria are harvested from aerated and non-aerated cultures respectively. Larger symbols indicate n=3, smaller symbols n=2.
