NRL Salmonella ringonderzoek IV en V (1999); Bacteriologische detectie van Salmonella in aanwezigheid van competitieve floraTranslated Title
Dutch National Reference Laboratorys collaborative studie IV and V on Salmonella (1999); Detection of Salmonella in the precence of competive micro-organismsPubliekssamenvatting
In 1999 zijn door het Nationaal Referentie Laboratorium (NRL) Salmonella 2 bacteriologische ringonderzoeken georganiseerd. Hieraan deden 26 laboratoria mee in het kader van het plan van aanpak Salmonella en Campylobacter in de pluimveehouderij. Het belangrijkste doel van deze ringonderzoeken was te testen of de deelnemende laboratoria in staat zijn om Salmonella te detecteren in aanwezigheid van stoorflora. Referentiematerialen met Salmonella Typhimurium moesten getest worden op Salmonella met en zonder toevoeging van kippenfeces. In het eerste ringonderzoek mochten de laboratoria de laboratorium-eigen methode voor onderzoek van pluimveemestmonsters gebruiken. In het tweede ringonderzoek was de PVE branchemethode verplicht, hierin wordt alleen MSRV als selectief ophopingsmedium gebruikt. Afhankelijk van de resultaten in eerdere ringonderzoeken moesten laboratoria 15 of 50 capsules onderzoeken.<br>In 1999, two bacteriological collaborative studies were organized by the Dutch National Reference Laboratory (NRL) for Salmonella among 26 laboratories participating in the Dutch national programme for control of Salmonella in the poultry sector. The main objective of these studies was to test the capacity of these laboratories to detect Salmonella in the presence of competitive micro-organisms. Reference capsules containing sublethally injured Salmonella Typhimurium had to be tested for the presence of Salmonella with and without the addition of chicken faeces. In the first study the laboratories were allowed to use the method they usually apply to detect Salmonella in chicken faeces. In the second study, however, the method was prescribed by the Product Boards for Livestock, Meat and Eggs. They had to use MSRV as selective enrichment medium. As a result of previous collaborative studies laboratories had to test 50 or 15 capsules.<br>
