Inactivation of Human Influenza Virus Using Gamma Irradiation

Inactivation of Plasmodium falciparum parasites using gamma-irradiation.

Inactivation of a human norovirus surrogate, human norovirus virus-like particles, and vesicular stomatitis virus by gamma irradiation.

Gamma irradiation is a nonthermal processing technology that has been used for the preservation of a variety of food products. This technology has been shown to effectively inactivate bacterial pathogens. Currently, the FDA has approved doses of up to 4.0 kGy to control food-borne pathogens in fresh iceberg lettuce and spinach. However, whether this dose range effectively inactivates food-borne...

Inactivation of Lassa, Marburg, and Ebola viruses by gamma irradiation.

Because of the cumbersome conditions experienced in a maximum containment laboratory, methods for inactivating highly pathogenic viruses were investigated. The infectivity of Lassa, Marburg, and Ebola viruses was inactivated without altering the immunological activity after radiation with Co60 gamma rays. At 4 degrees C, Lassa virus was the most difficult to inactivate with a rate of 5.3 X 10(-...

Inactivation of rubella virus by gamma radiation.

The Gilchrist and M-33 strains of rubella virus exposed in the frozen state to (137)Ce or (60)Co were inactivated exponentially according to "one hit" kinetics. There was no difference in the radiosensitivity of the two strains. Experimental D(37) values for both strains ranged from 1.9 x 10(5) to 2.9 x 10(5) rads, and computed radiosensitive molecular weights ranged from 2.6 x 10(6) to 4.0 x 1...

Inactivation of vaccinia virus by gamma radiation.

1,1mg I plus 0,42 mg DL-Phenylalanin-(l-14C) wur­ den in 15 cm3 Wasser gelöst. 1.22 mg II wurden in 15 cm3 Wasser mit 0,5 cm3 7i/lOO-NaOH in das wasser­ lösliche Mono-Natriumsalz überführt und 0,42 mg d l Phenylalanin-(l-14C) zugefügt. Versuchsdauer 48 Stun­ den. Die Isolierung und Reinigung der Isoflavone er­ folgte wie im vorigen Versuch. Ausbeuten: Versuch 1. 4,8 mg Biochanin-A und 1,88 mg F...
