Effects of rhodomyrtone on recombinant Streptococcus suis ParB-GFP nucleoid and septum positioning were visualized by immunofluorescence microscopy. Representative S. suis after 30 min exposure to a 1% DMSO, b 1 µg/ml rhodomyrtone, c 1 µg/ml rifampicin, and d 4 µg/ml quinolone were shown. Localization of Hoechst 33342 stained DNA (blue), ParB-GFP (green), FtsZ (red) and overlaid of three fluorescence colors (Merge) were shown. Arrow indicated the characteristic of Z-ring (FtsZ) placement at midcell (a). Arrows indicated misplaced Z-ring shifting away from midcell found in rhodomyrtone, rifampicin, and quinolone-treated cells (bd, respectively). Scale bars = 1 µm
