Summary
Fibroblasts growing on glass have microfilaments arranged in bundles. These can be demonstrated by indirect immunofluorescent technique using human antiactin serum or experimentally produced rabbit anti-actin serum. When monolayer cultures of epithelial cells and fibroblasts are infected with paramyxovirus, such as measles, mumps, Sendai and NDV, there is a striking decrease of the bundles. Rabies and adenoviruses do not seem to influence the staining of microfilaments. The microfilament decreasing effect in the cells correlates to the finding by SDS-polyacrylamide-gel-electrophoresis of actin within virions of the paramyxoviruses.
