[Cytogenetic characteristics of suckling mouse brain cell cultures, chronically infected with Japanese encephalitis virus].


The brain cells of the suckling mice line MSB-1-K-33 chronically infected by an attenuated variant of the Japanese encephalitis virus and of cell clones isolated from the later, had mainly a neartetraploid keryotype (the modal class 70-71 chromosomes). In metaphases of cloned cell populations, an increase of number of the chromosomes was especially obvious… (More)
