INACTIVATION OF VENEZUELAN EQUINE ENCEPHALOMYELITIS VIRUS BY GAMMA RADIATION
Abstract
Exposure of Venezuelan equine encephalomyelitis (VEE) virus at -70 C to 6,000,000 r gamma radiation (Co60) resulted in loss of lethality for young adult mice and guinea pigs and loss of capacity to produce plaques or cytopathic effects in tissue culture. The suckling mouse was more sensitive for detecting live virus in irradiated suspensions than the adult mouse or guinea pig. Live virus was demonstrable in preparations exposed to 6,000,000 r but not in suspensions exposed to 8,000,000 r or more. The rate of inactivation of VEE virus by gamma radiation was an exponential function of the dosage.
