Fig. 5. Disseminated CCHFV antigen is present in tissues with minimal or no pathology in short-course-vaccinated (-3D) and unvaccinated animals at 6 dpi.

Fig. 5

Top row: -28D vaccination; middle row: short-course (-3D) vaccination; bottom row: unvaccinated. In unvaccinated (no VRP, given DMEM alone) and short-course-vaccinated animals, CCHFV antigen (red; arrows) was present in scattered cells within the leptomeninges of the brain, ciliary body of the eye, valvular stroma of the heart, adrenal cortex, renal interstitium, pancreatic islets, ovarian follicles and stroma, uterine endometrial stroma, and gastric lamina propria and submucosa/serosa. No immunostaining was seen in the same tissue types from -28D vaccinated animals. Original magnifications: 20 × (heart, kidney, ovary, uterus, stomach); 40 × (brain, eye, pancreas, adrenal); scale bars are 50 μM. CCHFV immunohistochemistry with Fast Red chromogen.
