Microbiology of the food chain - Preparation of test samples, initial suspension and decimal dilutions for microbiological examination - Part 1: General rules for the preparation of the initial suspension and decimal dilutions (ISO 6887-1:2017)

This document defines general rules for the aerobic preparation of the initial suspension and of dilutions
for microbiological examinations of products intended for human or animal consumption.
This document is applicable to the general case and other parts apply to specific groups of products
as mentioned in the foreword. Some aspects might also be applicable to molecular methods where
matrices can be associated with inhibition of the PCR steps and consequently affect the test result.
This document excludes preparation of samples for both enumeration and detection test methods
where preparation instructions are detailed in specific International Standards.

Dieser Teil von ISO 6887 legt allgemeinen Regeln für die aerobe Herstellung von Erstverdünnungen und Verdünnungen für mikrobiologische Untersuchungen von Produkten fest, die für den Verzehr durch Menschen oder Tiere vorgesehen sind.
Dieser Teil von ISO 6887 gilt für den allgemeinen Fall und andere Teile gelten für spezifische Produkt¬gruppen, wie im Vorwort dargelegt. Einige Aspekte sind möglicherweise auch auf molekulare Verfahren anwendbar, bei denen Matrices mit der Hemmung von PCR Schritten in Zusammenhang stehen und folglich das Untersuchungsergebnis beeinflussen können.
Dieser Teil von ISO 6887 schließt die Vorbereitung von Proben für Untersuchungsverfahren zur Zählung und zum Nachweis aus, bei denen die Anweisungen für die Vorbereitung in spezifischen Internationalen Normen ausführlich dargelegt sind.

Microbiologie des aliments - Préparation des échantillons, de la suspension mère et des dilutions décimales en vue de l'examen microbiologique - Partie 1: Règles générales pour la préparation de la suspension mère et des dilutions décimales (ISO 6887-1:2017)

ISO 6887-1:2017 définit des règles générales pour la préparation de la suspension mère et des dilutions réalisées en aérobiose, en vue des examens microbiologiques des produits destinés à la consommation humaine ou à l'alimentation animale.
ISO 6887-1:2017 est applicable aux cas généraux et les autres parties s'appliquent aux groupes de produits spécifiques indiqués dans l'Avant-propos. Certains aspects peuvent aussi être applicables aux méthodes moléculaires dans lesquelles les matrices peuvent être impliquées dans l'inhibition des étapes de PCR et, de ce fait, affectent le résultat d'essai.
ISO 6887-1:2017 exclut la préparation d'échantillons en vue des méthodes de dénombrement et de recherche dans lesquelles les instructions de préparation sont détaillées dans des Normes internationales spécifiques.

Mikrobiologija v prehranski verigi - Priprava preskusnih vzorcev, osnovne suspenzije in decimalnih razredčin za mikrobiološko preiskavo - 1. del: Splošna pravila za pripravo osnovne suspenzije in decimalnih razredčin (ISO 6887-1:2017)

Ta dokument določa splošna pravila za aerobno pripravo osnovne suspenzije in razredčin za mikrobiološke preiskave izdelkov, namenjenih za prehrano ljudi ali živali. Ta dokument se uporablja za splošne primere, drugi deli pa veljajo za posebne skupine izdelkov, kot je omenjeno v predgovoru. Nekateri vidiki se lahko uporabljajo tudi za molekularne metode, kjer je mogoče matrice povezati z zaviranjem verižne reakcije s polimerazo, kar vpliva na rezultate preskusa. Ta dokument ne zajema priprave vzorcev za preskusni metodi za ugotavljanje števila in odkrivanje, kadar so navodila glede priprave podrobneje opisana v določenih mednarodnih standardih.
