PCR amplification of 16S rRNA gene of Listeria spp. with the expected size of 938 bp, in fertilizer samples obtained from organic farm B. Lane 1: 100 bp ladder. Lane 2: L. monocytogenes reference strains ATCC 19155. Lanes 3-8: presumptive Listeria spp. isolates from fertilizer samples. Lane 9: negative control.
