title: Safety assessment of commercial Enterococcus probiotics in Korea.
abstract: There have been concerns about possible pathogenicity and antimicrobial resistance in Enterococcus, which constitute more than 50% of probiotics in the worldwide market. In this study, Enterococcus in sixteen products manufactured by ten different companies was tested for the presence of six virulence genes and two vancomycin resistance genes. Results in this study showed the safety of Enterococcus on the Korean market and the importance of screening vanA, vanB, agg, cylA, esp, and gelE. Pulse-field gel electrophoresis showed that the sixteen isolates tested in this study are originated from three strains.
