TERC and infection: Two methods for detection of ori:ter were tested in vivo in an experimental murine infection model; qPCR, where the ori:terqPCR was given as a population mean, and fluorescence microscopy, where the ori:termic was deduced from direct analysis of single fluorescently labelled live bacterial cells (exemplified in Fig. 1, where oriC foci are displayed in green (GFP labelling) and terC foci are displayed in red (mCherry labelling)).
