Microscopic findings from autopsy of liver transplant recipient with fatal Ehrlichia muris eauclairensis infection, Minnesota, USA. A) Hematoxylin and eosin stain of lung tissue shows acute diffuse alveolar damage with intraalveolar edema (asterisk) and focal hyaline membranes. Scale bar indicates 100 μm. B) Hematoxylin and eosin stain of kidney tissue shows acute tubular injury (asterisk). Scale bar indicates 50 μm. C) Masson’s trichrome stain of the liver shows prominent zone 3 necrosis (asterisk) consistent with ischemic injury. Scale bar indicates 500 μm. D) Higher magnification of panel C shows the loss of hepatocytes (asterisk) near the central vein (zone 3). Scale bar indicates 100 μm.
