Localization of Streptococcus suis oriC (ParB-GFP) in representative cells at the different stages of the division was visualized by fluorescence microscopy. a–d Designated arbitrary time points of 15 min intervals (t = 0 to 60 min). Recombinant S. suis ParB-GFP cells were spontaneously expressed ParB-GFP (green) and were stained to visualize DNA (blue). Scale bar = 2 µm. ^aThe quantitation of ParB-GFP activity as determined by fluorescence signal was reported in arbitrary units
