(A) Representative confocal micrographs of BMMs infected with either wild type (2308), ∆bspF or or complemented ∆bspF (∆bspF::bspF) bacteria (red) for 24 h and immunostained for the TGN vesicular marker Stx6 (green) and GM130 (blue). Scale bars, 10 µm and 2 µm (insets). Magnified insets show the association between Stx6-positive vesicles and rBCVs.
