Enterococcus spp.
Enterococcus is a genus of Gram-positive bacteria that lives in the human gut as part of the normal microbiome. Common species include E. faecalis and E. faecium. In healthy amounts, they coexist with other microbes; when present in excess, Enterococcus can behave opportunistically, forming biofilms, irritating the gut lining, and—if it translocates—contributing to infections outside the gut (e.g., urinary tract).
Helpful context & related markers
-
Calprotectin: inflammation signal—helps gauge gut wall irritation.
-
Secretory IgA (sIgA): mucosal immunity; low levels predispose to overgrowth.
-
Pancreatic Elastase-1: low suggests poor enzyme output.
-
Bile markers / steatocrit (on other panels): bile insufficiency favors dysbiosis.
-
H. pylori (if present): can reduce acid and indirectly promote overgrowth.
FAQs
Does a high Enterococcus mean I have an infection?
Not necessarily. Stool qPCR shows abundance, not invasive infection. Clinical context is key.
Should I take Enterococcus-based probiotics?
Not during an Enterococcus overgrowth. Consider non-Enterococcus probiotics while you rebalance, then reassess.
Is a low result bad?
Usually no. Focus on symptoms and overall microbial diversity rather than boosting this single genus.
Takeaway: On GI-MAP, elevated Enterococcus spp. points to dysbiosis and digestive barriers (acid, bile, enzymes, motility) more than a frank infection. Fix the terrain—diet, digestion, and drivers—and the numbers often follow.
What does it mean if your Enterococcus spp. result is too high?
Enterococcus is a type of bacteria normally present in the gut in small amounts. On a GI-MAP report, elevated levels suggest an imbalance (dysbiosis) where this genus has overgrown relative to other microbes. While not always harmful, high Enterococcus can act opportunistically, irritating the gut lining, producing biofilms, and sometimes contributing to infections if it moves outside the gut.
Why levels may be high
-
Recent antibiotics or hospital exposure (Enterococcus often thrives after disruption of gut flora)
-
Low stomach acid, poor bile flow, or low pancreatic enzymes (reducing natural digestive defenses)
-
Diets high in sugars and refined carbohydrates that fuel bacterial overgrowth
-
Constipation or slow motility creating an environment where Enterococcus can expand
-
Low immune defenses in the gut (low secretory IgA)
Possible symptoms
-
Gas, bloating, or abdominal discomfort
-
IBS-like symptoms or post-meal fullness
-
Increased risk for urinary tract infections (via bacterial migration)
-
Low-grade inflammation in the gut
Why it matters
When elevated, Enterococcus can crowd out beneficial microbes and contribute to symptoms of dysbiosis. It is also known to be antibiotic-resistant in hospital settings, so reducing excess growth in the gut helps prevent potential downstream issues.
Supportive steps
-
Diet: Limit refined sugars and processed foods; emphasize diverse plant fibers and whole foods to rebalance the microbiome.
-
Digestion: Support stomach acid, bile flow, and enzyme activity if low—since weak digestion allows overgrowth.
-
Probiotics: Avoid probiotics containing Enterococcus species; focus instead on Lactobacillus and Bifidobacterium blends.
-
Targeted therapies: Clinicians may use herbal antimicrobials (e.g., berberine, oregano, garlic extracts) for short courses if overgrowth is significant and symptomatic.
-
Lifestyle: Support bowel regularity, stress management, and adequate sleep—all of which influence microbial balance.
When to retest
If treatment is undertaken, it’s common to retest in 8–12 weeks to see if Enterococcus levels have normalized and symptoms improved.
Takeaway: Elevated Enterococcus spp. on a GI-MAP points to gut imbalance, reduced digestive defenses, or diet/lifestyle factors favoring overgrowth. Addressing digestion, diet, and microbiome support helps restore balance and reduce symptoms.

What does it mean if your Enterococcus spp. result is too low?
Low or undetectable Enterococcus on your GI-MAP is usually not a concern and does not require treatment. Everyone’s gut is unique, and many people naturally carry lower levels without any health problems.
What it means
-
Enterococcus is a type of bacteria that normally lives in the gut.
-
Unlike certain “beneficial” bacteria (such as Bifidobacterium or Faecalibacterium), Enterococcus is not essential for digestion or gut balance.
-
Having low levels does not usually cause symptoms like bloating, diarrhea, or constipation.
Why your levels may be low
-
Recent antibiotics or antimicrobial herbs – these can reduce many bacteria temporarily.
-
Dietary choices – very restricted or low-fiber diets may lower gut bacteria overall.
-
Normal shifts in balance – sometimes it just reflects your unique microbiome mix.
Is it harmful?
-
Low Enterococcus is not harmful on its own.
-
In fact, lower levels may even reduce the chance of problematic overgrowth by strains seen in hospital infections.
-
It matters more if many different bacteria are also showing low — which could point to reduced gut diversity.
When to pay attention
Bring it up with your healthcare provider if:
-
You recently took antibiotics or antimicrobials (temporary changes expected).
-
Your GI-MAP shows multiple low commensal bacteria, suggesting broader imbalance.
-
You have ongoing digestive symptoms alongside low bacterial diversity.
How to support your gut overall
Instead of focusing on Enterococcus alone, the best approach is to keep your gut microbiome as a whole resilient and diverse:
-
Eat plenty of plant-based foods rich in fiber (veggies, fruits, beans, whole grains, resistant starch).
-
Include fermented foods like yogurt, kefir, sauerkraut, or kimchi (if tolerated).
-
Avoid unnecessary antibiotics or antimicrobials.
-
Support your lifestyle: reduce stress, sleep well, and stay physically active.
Takeaway
Low Enterococcus is not worrisome by itself. What matters most is overall gut balance and diversity, since this has the biggest impact on digestion and long-term health.
