title: [Influence of some substances on the titration of a poliovirus aqueous suspension (author's transl)].
abstract: Important changes of virus titer are observed when low concentration of mineral salts (NaCl, MgCl2, AlCl3) or detergents (Tween 80) are added to a poliovirus suspension in distilled water. Calf serum addition to these suspensions induces new variations of virus titer. The highest titre is obtained in isotonic medium with calf serum.
