Kao Corporation and Kitasato University have decided to provide the license of their patents free of charge for "technology for evaluating the inactivating effect of human norovirus on complex mixtures (products, etc.)".This is expected to develop an effective disinfectant for human norovirus.
Human norovirus (norovirus that infects humans) is a major virus that causes food poisoning that is prevalent in winter. There is no radical cure for human norovirus infection, and vaccines are under development.Therefore, in order to prevent the spread of food poisoning and infectious diseases caused by human norovirus, it is required to develop a disinfectant or the like that can inactivate human norovirus.
This patent (Patent No. 6777837) is a new method announced by Kao in July 2020 to evaluate the inactivating effect of human norovirus with a mixture as part of efforts to solve social hygiene issues. What the university owns.Specifically, when infecting intestinal organoids (organs) with human norovirus and evaluating the inactivating effect of various mixtures, components (surfactants, etc.) that may damage the intestinal organoids are used. It describes how to remove it properly.
In the past, it was not possible to evaluate the inactivation of a mixture (product, etc.) using human norovirus, so evaluation has been performed using a closely related alternative virus.By having this technology widely used, it will be possible to evaluate the inactivating effect of human norovirus on mixtures (products, etc.) consisting of complex components, and the development of disinfectants that are effective against human norovirus will progress. Is expected.
