The invention relates to a method for modifying the conditions of the interaction between the sensitive cells of a living host and a pathogen for this host, characterized by bringing these cells sensitive to this pathogenic agent into contact with anti-antibodies. -NP, or with NP molecules chemically modified via a covalent bond at the C1 position of the phenyl ring or its phenol position, by a chemical group for neutralizing the toxic properties in vivo of NP without, however affect its ability to be recognized by anti-NP antibodies, and this in particular under conditions of assay of anti-NP antibodies or detoxified NP, depending on the degree of modulation sought for the above interaction. |
