Methodological approaches to disinfection of human hepatitis B virus.
Three commercial disinfectants (two quaternary formulations and one phenolic) were tested against human hepatitis B virus (HHBV). The treated virus was assayed for infectivity by the chimpanzee assay and for morphological alteration by the Morphological Alteration and Disintegration Test. The same agents were tested against duck hepatitis B virus in a duck hepatocyte infectivity assay. It is apparent that human and duck hepatitis viruses were relatively susceptible to disinfection, becoming noninfectious after < or = 10 min of contact with the disinfectant. The Morphological Alteration and Disintegration Test accurately predicted activity in the two infectivity tests. The anti-human hepatitis B virus effect of the low-level quaternary ammonium germicides is a novel finding and suggest that members of the family Hepadnaviridae are relatively susceptible to chemical agents.
