Microbiology of food and animal feed - Horizontal method for determination of hepatitis A virus and norovirus in food using real-time RT-PCR - Part 2: Method for qualitative detection (ISO/TS 15216-2:2013, Corrected Version 2013-05-01)
ISO/TS 15216-2:2013 describes a method for qualitative detection of HAV and NoV genogroups I (GI) and II (GII), from test samples of foodstuffs or food surfaces. Following liberation of viruses from the test sample, viral RNA is then extracted by lysis with guanidine thiocyanate and adsorption on silica. Target sequences within the viral RNA are amplified and detected by real-time RT-PCR.
This approach is also relevant for detection of the target viruses on fomites, or of other human viruses in foodstuffs, on food surfaces or on fomites following appropriate validation and using target-specific primer and probe sets.
Mikrobiologie von Lebensmitteln und Futtermitteln - Horizontales Verfahren zur Bestimmung von Hepatitis A-Viren und Noroviren in Lebensmitteln mittels Real-time-RT-PCR - Teil 2: Verfahren für den qualitativen Nachweis (ISO/TS 15216-2:2013)
In diesem Teil von ISO/TS 15216 wird ein Verfahren zur qualitativen Bestimmung des Gehalts an RNS von HAV und NoV der Genogruppen I (GI) und II (GII) in Untersuchungsproben von Lebensmitteln oder Lebensmitteloberflächen beschrieben. Nach der Freisetzung der Viren aus der Untersuchungsprobe wird die virale RNS durch Aufschluss des Viruskapsids mit Guanidinthiocyanat und Adsorption an Silica(-Partikel) extrahiert. Die Zielsequenz innerhalb der viralen RNS wird mittels Real-time-RT-PCR amplifiziert und nachgewiesen.
Dieses Verfahren gilt nach einer entsprechenden Validierung und bei Anwendung zielmolekülspezifischer Primer- und Sondensätze auch für den Nachweis der Zielviren auf Virusträgern sowie für den Nachweis von anderen humanen Viren in Lebensmitteln, auf Lebensmitteloberflächen oder Virusträgern.
Microbiologie des aliments - Méthode horizontale pour la recherche des virus de l'hépatite A et norovirus dans les aliments par la technique RT-PCR en temps réel - Partie 2: Méthode de détection qualitative (ISO/TS 15216-2:2013, Version Corrigée 2013-05-01)
L'ISO/TS 15216-2:2013 décrit une méthode de détection qualitative des VHA et NoV des génogroupes I (GI) et II (GII) présents dans des échantillons pour essai d'aliments ou sur des surfaces alimentaires. Après libération des virus contenus dans l'échantillon pour essai, l'ARN viral est extrait par lyse à l'aide de thiocyanate de guanidine et par adsorption sur silice. Les séquences cibles de l'ARN viral sont amplifiées et détectées par la technique RT-PCR en temps réel.
Cette approche est aussi applicable pour la détection desdits virus sur des matières contaminées, ou d'autres virus humains dans les aliments, sur les surfaces alimentaires ou sur les matières contaminées en suivant une validation appropriée et en utilisant des jeux d'amorces et de sondes propres à la cible.
Mikrobiologija živil in krme - Horizontalna metoda za ugotavljanje virusa hepatitisa A in norovirusov v živilih z RT-PCR v realnem času - 2. del: Kvalitativna metoda (ISO/TS 15216-2:2013, popravljena verzija 2013-05-01)
Ta del ISO/TS 15216 opisuje kvalitativno metodo za določevanje genske skupine virusa hepatitisa A in norovirusa I (GI) in II (GII) v vzorcih ali živilih oz. na površinah živil. Po sprostitvi virusov iz vzorca se nato virusni RNK odstrani z lizo z gvanidinijevim tiocianatom in adsorpcijo na silicijev oksid. Ciljna zaporedja v virusni RNK poudari in zazna RT-PCR v realnem času. Ta pristop je pomemben tudi za odkrivanje ciljnih virusov na predmetih oz. drugih človeških virusov v živilih, na površini živil ali na predmetih, in sicer po ustrezni validaciji ter uporabi ciljno specifičnega primerja in kompletov sond.
