Abstract: 16 chicken isolates and four clinical isolates of VanB-vanA incongruent vancomycinresistant Enterococcus faecium strains without vanS were isolated in 1999. Pulsed-field gel electrophoresis revealed only a peripheral relationship between the chicken isolates and clinical isolates, but suggested clonal spread in the chicken isolates.

In vitro Activity of Sodium Benzoate Against Clinically Relevant Enterococcus faecalis and Enterococcus faecium Isolates: Oguz Karabay , Esra Kocoglu , Nevin Ince , Tufan Sahan , Davut Ozdemir; J. Microbiol. 2006;44(1):129-131.; DOI: https://doi.org/2325 [pii]

Abstract: The antimicrobial effects of sodium benzoate against Enterococcus faecalis and Enterococcus faecium were investigated. The MIC90 of sodium benzoate were 64 mg/L for E. faecalis and 32 mg/L for E. faecium, while the MBC90 were 128 mg/L and 64mg/L, respectively. Although further studies are required for clinical evidence, sodium benzoate seems to be effective against Enterococcus spp.

Optimization of Bacteriocin ST311LD Production by Enterococcus faecium ST311LD, Isolated from Spoiled Black Olives: Svetoslav D. Todorov , Leon M.T. Dicks; J. Microbiol. 2005;43(4):370-374.; DOI: https://doi.org/2251 [pii]

Abstract: Bacteriocin ST311LD is approximately 2.3 kDa in size. Low levels of bacteriocin activity were recorded in BHI and M17 broth (800 AU/ml) and in 10% (w/v) soy milk (3,200 AU/ml). No bacteriocin production was recorded in 10% (w/v) molasses, despite good growth. Optimal levels (12,800 AU/ml) were detected in MRS broth which had been supplemented with tryptone (20.0 g/l), saccharose (5.0 or 10.0 g/l) or vitamin C (1 ppm). Increased potassium levels did not result in higher levels of activity, and glycerol (1.0 g/l) inhibited the production of bacteriocin ST311LD.
