From: Killing of Mycobacterium avium subspecies paratuberculosis within macrophages
Some mycobacteria are degraded within macrophages. Infected macrophages were processed for transmission electron microscopy at 24 (A), 48 (B), 72 (C), 96 (D), and 120 (E) hours postinfection. Degraded, unrecognizable mycobacteria were labeled with immunogold particles (A-E). Healthy M. paratuberculosis bacilli at 72 hours postinfection were seen in (F). Magnification: 104,000 × (A-C), 104,000 × (D), 165,000 × (E), 88,400 × (F).
