title: Ocular lesions associated with dissemination of type 2 herpes simplex virus from skin infection in newborn rabbits.
abstract: The subcutaneous inoculation of the backs of New Zealand white rabbits 17 to 34 hr old with 10(3) 50% tissue culture infection dose (TCID50) of type 2 herpes simplex virus (HSV-2) induced cutaneous lesions within 24 hr, foci of disseminated infection in many organs (including the eye) on day 3 and thereafter, and the death of the animals on day 5 with infection of the central nervous system. Infectious HSV-2 could be isolated from the mononuclear cells and plasma of the peripheral blood, indicating the active role of both elements in the dissemination of the virus. Infectious HSV was also recovered from the corresponding sensory ganglia of the skin lesion (the cervicothoracic ganglia) as early as 2 days after the subcutaneous inoculation of the virus. About 40% of the animals developed ocular consisting of retinal folds with or without degenerative changes, Iritis and choroiditis also developed in some eyes. Infectious HSV-2 could be isolated from 33% of the eyes on days 4 and 5. Thus the newborn rabbit may serve as a suitable experimental animal for the study of HSV-2-induced chorioretinitis in the human newborn.
