Abstract

Cette invention concerne une analyse biologique permettant de détecter un virus apte à la réplication non sélective dans une préparation de virus à réplication sélective (RCV). Le procédé consiste à faire passer la préparation virale au moins une fois sur des cellules qui amplifient de manière différentielle le virus à réplication sélective par comparaison avec un virus apte à la réplication, puis à poursuivre l'analyse de la préparation virale pour y détecter la présence d'un virus apte à la réplication. La poursuite de l'analyse virale comprend une ou plusieurs des opérations suivantes : détection d'un effet cytophathique accru, détection d'une production virale, détection d'un pouvoir de destruction accru de cellules normales, détection d'un schéma de digestion de restriction altéré, détection d'une séquence génomique altérée, détection de recombinants attendus avec amplification de la réaction en chaîne de la polymérase et détection d'une hépato-toxicité aiguë chez un animal auquel on a administré la préparation virale. Dans un mode de réalisation, l'analyse permet de détecter des adénovirus aptes à la réplication dans une préparation d'adénovirus oncolytique.This invention relates to a biological analysis for detecting a virus capable of non-selective replication in a preparation of selective replication virus (RCV). The method comprises passing the viral preparation at least once over cells which differentially amplify the selectively replicating virus by comparison with a replicable virus, then continuing the analysis of the viral preparation to detect therein. presence of a replicable virus. The continuation of the viral analysis includes one or more of the following operations: detection of an increased cytophathic effect, detection of a viral production, detection of an increased destructive power of normal cells, detection of a pattern of digestion of altered restriction, detection of an altered genomic sequence, detection of expected recombinants with amplification of the polymerase chain reaction and detection of acute hepatotoxicity in an animal to which the viral preparation has been administered. In one embodiment, the analysis makes it possible to detect adenoviruses capable of replication in an oncolytic adenovirus preparation.
