AIDS and optic neuritis in a rhesus monkey infected with the R5 clade C SHIV-1157ipd3N4
A Chinese rhesus macaque infected with the pathogenic CCR5-tropic clade C simian-human immunodeficiency virus, SHIV-1157ipd3N4, had persistent viremia, depletion of CD4+ T cells to \u3c200 cells/渭l, opportunistic infections, coagulopathy, and gradual development of bilateral blindness. MRI revealed marked thickening of both optic nerves. Histopathological evaluation showed diffuse cellular infiltration at necropsy and a focus of SHIV-infected cells. This is the first report of CNS pathology following chronic infection with an obligate R5 SHIV

Longitudinal MRI Evaluation of Ischemic Stroke in the Basal Ganglia of a Rhesus Macaque (Macaca mulatta) with Seizures.
An adult rhesus macaque developed seizures after the induction of ischemic stroke. Initially, on the day of surgery, a focal ischemic lesion was present exclusively in the right caudate nucleus. By 48 h after stroke induction, the lesion had extended into the putamen, when a seizure was observed. Our report highlights the temporal changes in infarction of unilateral basal ganglia after acute stroke and the accompanying clinical symptoms. This unusual case may provide additional information regarding the involvement of the basal ganglia in seizures, given that prior case reports and studies usually have not described the temporal and spatial evolution of the lesion before clinical symptoms emerge
