Abstract
The present invention relates to a new test for detecting influenza viruses. This test comprises: 1- the addition of influenzia virus or of allantoic liquid containing said virus to neuraminidase substrate containing at least one sialic acid group. The substrate is fixed by covalent coupling to an appropriate insoluble solid support, it being understood that said substrate may be formed by all types of mucoproteins, oligosaccharides, mucopolysaccharides or mucolipids comprising at least one sialic acid group capable of being used as a neuraminidase substrate; 2- incubation of the influenza virus with its substrate for an appropriate length of time; 3- then reading the reaction.
