Applying the microarray (chip) DNA technique for bacteriological examinations of foodstuffs [Polish]

摘要

Conventional methods used in bacteriological examinations of foodstuffs are time-consuming and do not always result in the correct identification of the microorganism. For this reason laboratories more and more frequently employ highly sensitive, molecular techniques. One of them is the microarray DNA method. The aim of the study was to check the use of NUTRI(R)-Chip (GeneScan Europe AG, Germany) for the detection of the following bacteria: Campylobacter coli, Campylobacter was affirmed in four cases and Listeria monocytogenes in one case. Thanks to the existence of control spots on the chip, it was possible to avoid adulterating results. Moreover, microarray technique made it possible to obtain the results of the study in a relatively short period of time.
