Avian influenza virus (H5N1) inactivation by binary ethylenimine

Abstract

Avian influenza virus (AIV) subtype H5N1 is known as a highly pathogenic agent for man and various kinds of animals, especially avian species. Herein, AIV H5N1 was inactivated by binary ethylenimine (BEI), an aziridine compound, produced from 2-bromoethylamine hydrobromide. BEI was used at concentrations of 0.001 and 0.01 M for AIV inactivation. At the lower concentration (0.001 M), AIV could be inactivated within 24 hr. At the higher concentration (0.01 M), AIV could be inactivated within 6 hr. After inactivation, no hemagglutination activity had been found meaning that AIV had been completely inactivated.
