【Objective】

We examined antibacterial activities of Enterococcus faecalis TH10 against methicillin-resistant Staphylococcus aureus (MRSA) which is known as a bacterium causing nosocomial infection.

【Methods】

We extracted culture supernatant fluids of Enterococcus faecalis TH10. We prepared the extract apt for the test and performed an antibacterial test with a paper disk method.

【Results】

The prepared extract from culture supernatant fluids of Enterococcus faecalis TH10 showed a potent antibacterial activity against MRSA and a modest antibacterial activity against methicillin-sensitive Staphylococcus aureus. No antibacterial activity was observed in Enterococcus genus. We considered that Enterococcus faecalis TH10 is different from bacteriocin which shows antibacterial activity against the related species of lactic acid bacteria.
