The survival of Aujeszky''s disease (pseudorabies) virus outside the living host was found to be dependant on pH level and temperature. Virus inactivation occurred at a rate varying from 0.04 log/day at 4.degree. C to 0.6 log/day at 37.degree. C at the optimum pH levels of 6-8. Fluctuation of the temperature between 4 and 37.degree. C had no apparent effect on the virus titer. At a steady temperature of -13.degree. C, the virus was rapidly inactivated at all tested pH levels. For long-term storage it is recommended that the pH should be adjusted to 6-7, that suspensions should be kept at -90.degree. C and that freezing and thawing should be rapid so as to pass through the just subzero temperature zone as quickly as possible. Drying, on glass and gelatin, caused inactivation of the virus at all pH levels, as did exposure to UV light.
