Abstract
Für den holländischen Vanillepudding (Vla) wurde der ELISA-Test zum Nachweis von Staphylokokken-Enterotoxin-B (SEB) geprüft. Dabei zeigte sich, daß die fur einen serologischen Nachweis (Ouchterlony-Test) notwendige Aufarbeitung weitgehend verkürzt, and damit der erforderliche Arbeitsaufwand entscheidend reduziert werden kann. Die Empfindlichkeit des ELISA-Tests reicht aus, um nach zwei aufeinanderfolgenden Extraktionen bei pH 7,4 und pH 4,5 and anschließender Konzentrierung (1:20) noch 0,1 mcg SEB in 100 g Probe nachzuweisen. The ELISA for the detection of staphylococcal enterotoxin type B (SEB) was employed to demonstrate SEB in Dutch Vanilla custard. Due to the sensitivity of the ELISA the extraction procedure, which is necessary when the Ouchterlony test is used, can be abbreviated to a great extent. Two successive extractions at pH 7.4 and pH 4.5 followed by a concentration (1:20) was sufficient to detect 0.1 mcg SEB in 100 g custard.Keywords
