Abstract

A 3.5-year-old adult female rhesus macaque (Macaca mulatta) manifested swelling of the left upper eyelid and conjunctiva and a decline in clinical condition 18 days following intramuscular challenge with Ebola virus (EBOV; Kikwit-1995), after apparent clinical recovery. Histologic lesions with strong EBOV antigen staining were noted in the left eye (scleritis, conjunctivitis, and peri-optic neuritis), brain (choriomeningoencephalitis), stomach, proximal duodenum, and pancreas. Spleen, liver, and adrenal glands, common targets for acute infection, appeared histologically normal with no evidence of EBOV immunoreactivity. These findings may provide important insight for understanding sequelae seen in West African survivors of Ebola virus disease.
