Glycoprotein-mediated biological properties of a host range mutant of Junin virus

The biological properties mediated by the main envelope glycoprotein (GP1) of a mouse-attenuated mutant of Junin virus, named Cl67, were investigated in comparison with its parental strain XJCl3. In contrast to the parental strain, this mutant was unable to multiply in primary cultures of mouse embr...
