Understanding Biofilm in Stool: What You Need to Know as a Patient and Practitioner

Biofilm in stool and gut have significant implications for health and well-being, as disruptions to intestinal mucus surfaces caused by biofilms may indicate disease. About 80% of ongoing bacterial infections are linked to biofilms. Healthy gut microbiome balance is vital to maximize body functioning; harmful biofilms in stool may hinder this.

This article for practitioners and patients explains the importance of understanding biofilm in the gastrointestinal tract. It’s an informational guide for lab tests, biomarkers, and treatment strategies to achieve microbiome balance.

What is Biofilm?

Biofilms are jellylike, slimy layers of microorganisms that stick to surfaces. Examples include plaque that forms on the teeth and a layer of microorganism groups that form in the inner lining of the digestive tract.

Bioflims may consist of fungi, bacteria, and communities of microorganisms joining together on surfaces to become more resistant to hostile environments, such as exposure to antibiotics. Biofilms consist of bacteria that are 1,000 times more antibiotic-resistant, which can be problematic when developing treatment plans for infections.

While some biofilms may cause health problems, others are helpful bacterial biofilms. The disruption of the good films and abnormal adherence to intestinal surfaces can lead to health concerns.

Biofilms form in the GI tract when intestinal molecules, flora, and host mucosa cells connect, giving bacteria a better ability to withstand environmental stressors. However, researchers found that GI tract biofilms are linked to chronic mucosal diseases, such as:

Inflammatory bowel disease (IBD)
Chronic gastritis
Colorectal cancer
Irritable bowel syndrome (IBS)
Ulcerative colitis
Adenomas
Crohn's disease
Diverticular disease
GI bleeding
Gastrointestinal (GI) disorders

IBD and IBS affect more than 10% of the Western population.

These and similar diseases are linked to specific biofilm markers, which may help detect the presence of gastrointestinal diseases and their risk factors.

Identifying Biofilm in Stool

Common signs and symptoms indicating the presence of biofilm in the gut include:

Gastrointestinal bleeding
Diarrhea
Constipation
Abdominal pain or cramping
Bloating
Inflammation
Unbalanced gut bacteria
Bowel dysregulation

Biofilms can create a barrier to absorbing bile acids and other gut molecules, possibly explaining these or similar symptoms.

Biofilms can develop because of bacterial overgrowth. Researchers found that biofilm formation in the gut may disrupt the mucous layer, increase contact with harmful microbes, and reduce the ability to clear infections.

Studies also show that mature biofilm detection on previously healthy GI tissue may indicate a damaged gut. For example, E.Coli biofilms could be an early sign of ulcerative colitis. Researchers suggest that patients with IBD often receive antibiotics to alleviate their symptoms, which can cause dramatic GI microbiota changes.

Lab Tests for Detecting Biofilm

Standardized lab tests can detect biofilm in stool or the gut, which could be an indicator of gastrointestinal problems. Examples include:

Stool Culture Tests

Stool culture tests are a simple way to detect the presence of biofilms and bacterial overgrowth. They identify bacteria that commonly cause infections in the gastrointestinal tract.

Direct Microscopic Examinations

Technicians can detect biofilms via imaging technology, including electron microscopy, light microscopy, and confocal microscopy, to identify biofilms and observe their 3D structures.

Polymerase Chain Reaction (PCR) Testing

PCR testing helps identify specific pathogens by amplifying nucleic acid sequences to detect biofilm-linked genes.

Congo Red Agar Test (CRA)

CRA is a rapid, sensitive assay that detects biofilm-producing organisms based on color changes. For example, black colonies indicate robust biofilm production and red colonies indicate a lack of biofilms.

Tube Biofilm Formation Test

Tube biofilm formation tests can detect biofilm-producing microorganisms using stained isolates incubated in plastic test tubes.

Microtiter Plate Assay

Microtiter plate assays provide a quantitative method of measuring biofilm production by staining and incubating isolates in microtiter plates.

Additional Testing and Biomarkers

Additional testing options for comprehensive biofilm analyses include:

Metagenomic Sequencing

Metagenomics uses culture-independent methods to characterize and identify organisms present in various samples.

Biofilm-Specific Staining Techniques

Staining biofilms with crystal violet or safranin helps determine total biofilm mass during microplate testing.

Inflammatory Markers

The following inflammatory markers can detect GI inflammation linked to biofilm production:

Microbial Markers

Examples of microbial markers that help detect specific fungi, bacteria, or other microbes include:

Immune Response Indicators

Consider the following immune system response tests to detect the effects of biofilms:

Treatment Strategies: Biofilm Disruptors

Fortunately, treatment can disrupt harmful biofilms to optimize gastrointestinal and overall health. Examples of biofilm disruptors include:

Natural Biofilm Disruptors

Natural biofilm disruptors based on research studies include:

Enzymes

Nattokinase
Lumbrokinase
Alginate lyase enzymes with polyM/G activity

Herbal Remedies

‍Amino Acids

Probiotics

Studies show that because probiotics produce organic acids, lactic acid, enzymes, hydrogen peroxide, and other antagonistic substances — and support balanced immune function and a healthy gut microbiome — they can inhibit biofilm formation and remove preformed biofilms.

Pharmaceutical Biofilm Disruptors

Some practitioners treat GI biofilms with antibiotics, biofilm-targeted therapies (such as DNase), other medications, or combinations of treatments. However, researchers suggest that conventional therapies like phage therapy, antibiotics, monoclonal antibody therapy, and QS inhibitors do not efficiently treat biofilms.

Studies show that the presence of biofilms can increase the need for doses of antibiotics of up to 1,000-fold to eliminate infections.

Integrative Approaches to Managing Biofilm

Providers should consider natural solutions to reduce biofilms or combine natural with pharmaceutical treatments.

Researchers suggest that alginate lyase enzymes with polyM/G activity enhance the effects of antibiotics in addition to destroying harmful biofilms. Diet and lifestyle modifications, such as taking probiotics and prebiotics, play a vital role in supporting optimal gut health.

Case Studies and Practitioner Insights

A case study involving the treatment of biofilm in stool and IBS included a 21-year-old female patient complaining of postural orthostatic tachycardia syndrome (POTS), nausea, fatigue, headaches, and syncope.

She was diagnosed with mixed irritable bowel syndrome but had stable digestion with well-formed bowel movements. However, after being treated for POTS symptoms, she developed bloating, abdominal pain, urgency after meals, diarrhea, constipation, and foul-smelling flatulence.

Her symptoms improved after drinking pink Himalayan salt in water, consuming whole foods, reducing endocrine disruptors, exercising regularly, stretching, using castor oil packs, and taking vitamin C and collagen powder supplements. She avoided added sugar, alcohol, cheese, vinegar, and yeast.

She also completed a liver cleanse (Thorne); took L-glutamine supplements to preserve gut lining integrity during the breakdown of biofilm; and used sunbutyrate to support short-chain fatty acid intake, healing, and cell turnover.

The patient continued with her treatment plan by trying biofilm defense capsules, activated charcoal, lymphatic drainage, castor oil packs, and the following antimicrobial supplements:

Phytostan
Garlic
Coconut oil
Matcha powder
Oregano
Onion
Thyme
Ginger
Dandelion
Burdock root tea
Leeks
Turmeric
Citrus

The end result was a 90% improvement in GI symptoms.

Natural medicine physician David Jockers, DNM, DC, MS, suggests that the following natural remedies to reduce biofilm:

Curcumin
Apple cider vinegar
Garlic
Oregano
Activated charcoal
Berberine
Proteolytic enzymes

Amy Myers, MD, suggests avoiding inflammatory foods like dairy, gluten, added sugar, food additives, trans fats, alcohol, and preservatives. She suggests taking supplements containing sweet wormwood, black walnuts, and other holistic ingredients to disrupt harmful biofilms.

While natural remedies are generally safe and often more effective than traditional medications for reducing harmful biofilms, individuals should always ask a healthcare provider before trying new dietary supplements.
