title: Host genetics and the behavioral sequelae to herpes encephalitis in mice.
abstract: The effects of intracerebral infection with herpes simplex virus on the subsequent behavior of two strains of mice were examined. Infected Nya:NYLAR mice were hyperactive and did not show any deficits in the acquisition or reversal of a spatial learning task. In contrast, infected Nya:(SW) mice were hypoactive and made more errors than controls during both phases of the learning tasks. These differences in the nature of the sequelae to infection were related to an overall higher virus titer in the brains of Nya:(SW) mice, an effect particularly marked in the cerebral hemispheres. The results suggest that herpes encephalitis may produce a variety of behavioral syndromes, depending in part on the genetic background of the host. The relevance of these findings to clinical disorders produced by viral infection is discussed.
