[Adsorption of enteroviruses on nitrate cellulose membranes: influence of mineral salts, detergents and calf serum (author's transl)].

The filtration through cellulose nitrate membranes of a poliovirus type II suspension in distilled water alone or with added mineral salts (NaCl, MgCl2, AlCl3) results in adsorption of the virus. The maximal adsorption is obtained with NaCl. A detergent in the virus suspension or a pretreatment of the membranes with calf serum prevents this adsorption. Elution of the adsorbed enteroviruses is achieved with alcaline and proteinaceous buffer.
