Results of SEM analysis. A Neutrophil aggregate around a large bacterial clump (center left) and a smaller clump (upper right). B Detail of (A), delicate NETs (arrowheads) can be seen extruded from some of the neutrophils and amidst the bacilli, where some of them are decorated with small globular domains. C Detail of a single neutrophil undergoing NETosis over a bacterial clump. D Neutrophils surround a small bacterial clump and release short NETs, the two on the lower right are seemingly phagocytosing bacteria, on the left corner the remnants of an apoptotic neutrophil and NETs can be observed. Representative images (n = 3).
