AB The main objective of this study was to detect the antimicrobial activity and the presence of bacteriocin structural genes in 224 enterococcal isolates from fecal origin obtained from humans, pets, wild animals and birds. Direct antimicrobial activity against Listeria monocytogenes CECT4032 was detected in 102 (45.6%) of the tested isolates. From these, only 22 displayed bacteriocin activity against this indicator. The bacteriocinogenic strains contained one or more of the bacteriocin structural genes tested in this study, with those of enterocins P, A and L50 (L50A and L50B) being the most abundant. Our results show a high occurrence of the combination of different bacteriocin structural genes in the enterococcal isolates analyzed, indicating an elevated genetic potential of these strains to produce various bacteriocins.
