FIG. 5.

Flagellin B levels increase under conditions of high pressure and increased viscosity. Shown are results of semiquantitative RT-PCR analysis of flaB from cells grown under conditions of high pressure (HP) or atmospheric pressure (AT), with or without increased viscosity (HV) (5% PVP-360). Lane 1, 2-log ladder (New England Biolabs); all other lanes are as marked. The upper band is an internal fragment of flaB; the lower band is a constitutively expressed control gene, uridine phosphorylase (udp; PBPRA1431).
