EFFECTS OF ACETONE, ULTRAVIOLET IRRADIATION AND FORMALIN ON WEST NILE VIRUS INFECTIVITY AND IMMUNOFLUORESCENT ANTIGENICITY

Journal Article · · Proc. Soc. Exptl. Biol. Med.
An effort was made to ascertain whether infectious virus in thin sections could be inactivated without destroying either the antigenicity of the virus or the integrity of the tissue. Adjacent sections of the head from a suckling mouse dying of the Egypt 101 strain WN virus infection were exposed for varying lengths of time to the atmosphere (in the dark), to ultraviolet light, and to acetone (analytic grade) at room temperature, or to 10% buffered formalin at 4 deg C. Infectivity of West Nile Virus in frozen sections was inactivated by UV light in a matter of minutes while antigenicity persisted for several hours. Immersion of infected frozen sections in acetone inactivated 99% of virus infectivity in minutes yet antigenicity was not impaired for up to two weeks at room temperature. In our hands fixation by formalin was found to be unsatisfactory. (auth)
