HTLV-I uveitis in a rabbit.

An animal model of HTLV-I associated uveitis was created. One rabbit developed bilateral uveitis 3,5 years after being injected with blood from an HTLV-I-infected rabbit. The proviral DNA of HTLV-I was detected by polymerase chain reaction and dot-blot hybridization in the aqueous humor of the anterior chamber and the vitreous body. Histopathological examination revealed marked corneal opacity with neovascularization and infiltration of inflammatory cells, mainly plasma cells, into the iris, ciliary body, and choroid. Complicated cataracts were also seen. The retinas were destroyed and replaced by gliosis. This is the first animal model of HTLV-I-associated disease to be reported.
