If you have high enterococcus reported, please verified that none of the probiotics that you have taken included enterococcus in the prior month. If so, this may be just residue from those probiotics.
“Vancomycin-resistant enterococci (VRE) are both of medical and public health importance associated with serious multidrug-resistantinfections and persistent colonization. Enterococci are opportunistic environmental inhabitants with a remarkable adaptive capacity to evolve and transmit antimicrobial-resistant determinants. The VRE gene operons show distinct genetic variability and apparently continued evolution leading to a variety of antimicrobial resistance phenotypes and various environmental and livestock reservoirs for the most common van genes. Such complex diversity renders a number of important therapeutic options including “last resort antibiotics” ineffective and poses a particular challenge for clinical management. Enterococci resistance to glycopeptides and multidrug resistance warrants attention and continuous monitoring.” 
- Trametes versicolor
- Glycyrrhizic acid
- Polymannuronic acid
- Glyphosphate ( an organophosphorus compound – avoid)
- Resistant starch (type IV)
There are 25000+ studies on PubMed — this is just from a select sampling.
- ” The incidence of Hirschsprung-associated enterocolitis with/without probiotics [Lactobacillus, Bifidobacterium, Streptococcus, and Enterococcus] was 22.6 and 30.5%, respectively, but this was not statistically different (OR 0.72; 95% CI 0.37-1.39; P = 0.33).” 
- “L. reuteri strains tested were able to inhibit and displace (P < 0.05) the adhesion of …. Enterococcus faecalis NCDC115. The probiotic strain L. reuteri LR6 showed the strongest adhesion and pathogen inhibition ability among the eight L. reuteri strains tested” 
- ” Lactobacilli (Lactobacillus plantarum ATCC 8041 and Lactobacillus rhamnosus ATCC 7408 ) had an inhibitory effect on the growth of E. faecalis by agar cup method but not by deferred antagonism test.” 
- “Lactobacillus strains ((L. gasseri, L. rhamnosus, L. acidophilus, L. plantarum, L. paracasei, L. acidophilus) ) had similar moderate antimicrobial activities against uropathogens.” 
- ” all the Lactobacillus isolates[Lactobacillus acidophilus, L. paracasei, L. delbrueckii, L. casei, L. helveticus, L. brevis, L. salivarius, L. fermentum, L. rhamnosus, L. animalis, and L. plantarum} displayed antimicrobial activity against 6 out of 7 antibiotic-resistant uropathogens (E. fecalis….), L. fermentum and L. plantarum strains demonstrated remarkable inhibitory activities against E. faecalis,” 
- “No decline in (enterococci) colony counts was seen over time in subjects who received Lactobacillus rhamnosus GG . ” 
This is a tough genus to reduce — antibiotics are likely to do more harm than good because of the high resistance reported. Many probiotics have only a moderate effect at best.
- Lactobacillus Plantarum
- Lactobacillus Fermentum
- Triphala (see this post)
- Hyperiform (St. John’s Wort)
- Glycyrrhizic acid (a.k.a. Licorice)
- Resistant starch (type IV)
- Propolis (from bees)
Personally, I tend to use Triphala, Lactobacillus Fermentum, and Licorice as part of my regular maintenance routine.
