Mutant of Polyoma Virus with Impaired Adsorption to BHK Cells

ABSTRACT

A mutant of polyoma virus PY235 has an impaired adsorption to guinea pig red blood cells and BHK-21 hamster cells. Adsorption to 3T3 mouse cells is much less inhibited. These altered adsorption properties are responsible for the apparent inability of PY235 to cause cell transformation or hemagglutination.
