A: Liver at 9 days after infection. LHI in the hepatic lobule and Kupffer cell hyperplasia (H&E). B: Liver at 30 days after infection. Prominent perivascular infiltrates with well-formed granulomas (arrows). Kupffer cell hyperplasia (H&E). C: Liver, day 14 after infection. Ehrlichial morulae in sinusoidal mononuclear cells (horseradish peroxidase/diaminobenzidine). D: Lung, day 9 after infection. Focal LHI (arrow) in the lung interstitium (H&E). E: Lung, day 20 after infection. Interstitial, perivascular (arrow), and peribronchial (arrow) LHI (H&E). F: Lung, day 14 after infection. Ehrlichial morulae in mononuclear cells infiltrating the lung interstitium (horseradish peroxidase/diaminobenzidine). G: Section of spleen at day 4 after infection. Infiltration of red pulp and marginal zone by macrophages (H&E). H: Spleen section at day 14 after infection. Markedly irregular lymphoid follicles and macrophage infiltration of red pulp (H&E). I: Spleen at day 10 after infection. Ehrlichial morulae in macrophages infiltrating red pulp (horseradish peroxidase/diaminobenzidine). Original magnifications: ×200 (A, B, D); ×1000 (C, F, I); ×100 (E, G, H).
