Figure 4From: Effect of apo-lactoferrin on leukotoxin and outer membrane vesicles of Mannheimia haemolytica A2Holo-BLf does not affect the OM and OMV structure ofM. haemolyticaA2. Bacteria (left side) and purified OMVs (right side) were grown in BHI supplemented with different concentrations of holo-BLf (2, 4, 6 and 8 µM). Arrows, OMVs; circles and ovals, a set of OMVs. Electron transmission microscopy, negative staining.Back to article page
