Immunohistochemistry for myeloperoxidase (MPO)-positive neutrophils, vervets, multiple organs. (A) Y. enterocolitica- positive vervet, mesenteric lymph node, case 6. Neutrophils are present within the medullary sinus of a mesenteric lymph node adjacent to the affected colon. (B) Control vervet, mesenteric lymph node. Neutrophils are rarely observed within the control lymph node. (C) Y. enterocolitica- positive vervet, placenta, case 20. MPO-positive neutrophils are abundant within areas of placental necrosis. (D) Control vervet, placenta. Few neutrophils are present within the placenta, and often associated with physiologically normal areas of coagulative necrosis and mineral. (E) Y. enterocolitica- positive vervet, colon, case 3. MPO-positive neutrophils are prominent within mucosal lesions. Neutrophils are also present within veins and lymphatic vessels of the muscularis mucosa. (F) Control vervet, colon. Neutrophils within the control colon are rare and mainly within the lamina propria. (G) Y. enterocolitica- positive vervet, lung, case 1. Extravasated neutrophils are abundant within lesions of the lung. (H) Control vervet, lung. MPO-positive neutrophils are present only within blood vessels of the control lung.

Immunohistochemistry for CD11c, vervets, multiple organs. (A) Y. enterocolitica- positive vervet, mesenteric lymph node, case 6. Approximately 20% of cells within the lymph node medullary sinus stain positively for CD11c. (B) Control vervet, mesenteric lymph node. CD11c-positive antigen-presenting cells (APCs) make up about 80% of the cells within the cortex and medullary sinuses of the lymph node. (C) Y. enterocolitica- positive vervet, placenta, case 20. CD11c-positive APCs are centered on areas of necrosis and are also increased in maternal blood. (D) Control vervet, placenta. CD11c-positive cells are rare within the control placenta. (E) Y. enterocolitica- positive vervet, colon, case 3. CD11c-positive cells are prevalent within lesions. (F) Control vervet, colon. Two CD11c-positive APCs are present within the colonic mucosa. (G) Y. enterocolitica- positive vervet, lung, case 1. Abundant CD11c-positive cells are found within necrotic lesions. (H) Control vervet, lung. CD11c-positive cells are numerous but confined to the interstitial space of the control lung.
