The results of amplification of nucleic acids extracted from the samples using universal primers specific for the 16S rRNA gene. Lane 1: tampon number 1, 2: washout from the cavity number 1, 3: membrane of tampon number 2, 4: washout from the tampon number 2, 5: membrane of washout number 2, 6: washout from the cavity number 2, 7: membrane of washout number 1, 8: tampon number 2, 9: tampon number 2, 10: membrane of tampon number 1, 11: negative control (PCR k−). Molecular weight markers (step 100 bp.) are applied on the last lane.
