Plant biostimulants - Detection of Shigella spp.

This document provides a method for verifying that the pathogen Shigella spp. is not present in microbial plant biostimulants in a concentration that exceeds the respective limits outlined in the EU Regulation on Fertilising Products.
The detection method for Shigella pathogens is not sensitive and quantification is rarely performed. Detection is usually performed using an enrichment medium followed by subculturing onto a variety of selective media.

Pflanzen-Biostimulanzien - Nachweis von Shigella spp.

Dieses Dokument liefert ein Verfahren zum Nachweis, dass das Pathogen Shigella spp. in mikrobiellen Pflanzen-Biostimulanzien nicht in einer Konzentration vorhanden ist, die die jeweiligen Grenzwerte überschreitet, die in der EU Düngeprodukteverordnung festgelegt sind.
Das Nachweisverfahren für Shigella-Pathogene ist nicht trennscharf, und eine Quantifizierung wird selten durchgeführt. Der Nachweis erfolgt in der Regel mit einem Anreicherungsmedium und anschließender Subkultivierung auf verschiedenen Selektivmedien.

Biostimulants des végétaux - Recherche de Shigella spp.

Le présent document fournit une méthode permettant de vérifier que le pathogène Shigella spp n’est pas présent dans les biostimulants microbiens des végétaux à une concentration dépassant les limites correspondantes indiquées dans le Règlement UE sur les fertilisants.
La méthode de détection des pathogènes Shigella n’est pas sensible et la quantification est rarement réalisée. La détection est généralement réalisée en utilisant un milieu d’enrichissement, puis en procédant à un repiquage sur une variété de milieux sélectifs.
