Abstract

Theiler's virus, a murine picornavirus, is responsible for two different types of disease: strains DA, BeAn, and WW persist for more than a year in the white matter of the central nervous system and cause primary demyelination; strains GDVII and FA, on the other hand, cause an acute encephalitis that kills the host in a matter of days. To map the regions of the viral genome responsible for persistence and demyelination, cDNA clones of the entire genomes of the DA and GDVII strains were constructed and cloned into Bluescript plasmid (A. McAllister, F. Tangy, C. Aubert, and M. Brahic, Microb. Pathogen. 7:381-388, 1989; F. Tangy, A. McAllister, and M. Brahic, J. Virol. 63:1101-1106, 1989). We constructed chimeric viruses obtained by exchanging regions between the cDNA clones. Analysis of the disease phenotypes produced by the chimeric viruses allowed us to map persistence and demyelination to a genome segment coding for the VP1 capsid protein and 27 amino acids of protein 2A.
