• “Candida albicans remains the fungal species most commonly associated with biofilm formation.”
• “…formation of Candida biofilms carries important clinical repercussions because of their increased resistance to antifungal therapy and the ability of cells within biofilms to withstand host immune defenses.”
• “Biofilm formation on medical devices can negatively impact the host by causing the failure of the device and by serving as a reservoir or source for future continuing infection.”

Candida Transformation
• To infect host tissue, the unicellular form of Candida switches to a more invasive form based on environmental stressors.
• Examples: pH, food supply, temperature, CO2 at the tissue level.
• Candida can control its environment too to become invasive.
YOUR LOGO
YOUR LOGO
Candida Transformation and Biofilm Formation
• Heat shock proteins (HSP) – these specialized proteins are designed to prevent against protein unfolding and aggregation, caused by environmental stress, which normally induces cell death. HSPs are involved in Biofilm formation, morphogenesis, virulence, and drug resistance too.
• Metal accumulation – Candida acquires iron, zinc, manganese and copper for metabolic survival, with iron and zinc as primary minerals.
YOUR LOGO
Adhesins and Invasins
• Candida has specialized proteins which allow it to adhere to other microorganisms, abiotic surfaces, host cells and tissues (biotic surfaces). These adhesion proteins are also involved in Biofilmformation.
YOUR LOGO
Candida Biofilm Formation
Candida biofilms form in a sequential process:
1. Adherence of yeast cells
2. Proliferation
3. Hyphal cell formation in upper biofilm layer
4. Extracellular matrix material accumulation and dispersion of yeast cells from biofilm.

Contact Sensing
• Contact with certain surfaces will induce yeast cells to switch to hyphal transformation and biofilm formation.
• Thigmotropism – different topography, i.e. ridges will induce hyphal invasiveness damaging adjacent cells and tissues.
• Secreted hydrolases – protease, phospholipases, and lipases.

APMIS Suppl.2013 May;(136):1-51“The role of bacterial biofilms in chronic infections.”
Bjarnsholt, T. et.al.
• “Bacteria have two life forms during growth and proliferation. In one form, the bacteria exist as single, independent cells (planktonic) whereas in the other form, bacteria are organized into sessile aggregates. The latter form is commonly referred to as the biofilm growth phenotype.”
• “Acute infections are assumed to involve planktonic bacteria, which are generally treatable with antibiotics, although successful treatment depends on accurate and fast diagnosis.”
• “In cases where the bacteria succeed in forming a biofilm within the human host, the infection often turns out to be untreatable and will develop into a chronic state.”
• “The important hallmarks of chronic biofilm-based infections are extreme resistance to antibiotics and many other conventional antimicrobial agents, and an extreme capacity for evading the host defenses.”
YOUR LOGO
• Although enteric biofilms are likely in a steady state of shedding and regrowth, and although the percentage of epithelium covered with biofilms is unknown…
• “There is no doubt that biofilms are indeed present in the normal bowel.”
• It is not overly surprising to observe biofilms in the normal colons of humans since similar observations have been made in the normal colons of laboratory animals as diverse as mice.
Gut. 2007 Oct; 56(10): 1481–1482. “Biofilms in the normal human large bowel: fact
rather than fiction” R Randal Bollinger, et.al.

Biofilm Resistance
Biofilms have different levels of resistance:
1. Complex architecture of biofilm
2. The biofilm matrix
3. Efflux pumps
4. Metabolic plasticity

Quorum Sensing
YOUR LOGO
Quorum Sensing
• The ability of a single organism, i.e. yeast or bacteria to sense how many other organisms are in its vicinity and allowing it to join up with the biofilm colony.
• Can occur amongst a specific species or varied species. For example, different bacteria or bacteria and yeast.
• P. aeruginosa – and the creation of biofilms in cystic fibrosis.

Observed Clinical Indicators:
Lack of stool culture findings for yeast and/or bacteria:• However, by clinical history, individual seems to improve
when placed on antibiotics or antifungal medication or botanicals.
No Improvement With Antifungal or Antibacterial Treatment – Think Biofilm Problem
YOUR LOGO
Individuals with Obsessive-Compulsive Disorder (OCD), or other MH or physical problems:• Who tend to get worse seasonally or worsen with strep
exposure (may or may not test positive), or who have recurrent infections despite benefit of antibiotic treatment.
Persistent yeast and/or bacteria infections despite treatment:• As evidenced on Organic Acids Test such as arabinose
for yeast or HPHPA and/or 4-cresol for clostridia bacteria.

General Recommendations for Implementing Biofilm Program
• Avoid implementing biofilm program for a ‘new’ parent just getting starting with anti-pathogen treatment.
• Determine how sensitive patient is to initial antimicrobial remedies.
• Expect “die-off” with initial implementation of biofilm supplements. Go slow at first:• Start with before breakfast dose of enzyme for 5 to 7 days before
adding a before lunch or dinner dose.
• Also, consider starting ½ dose for sensitive individuals.
• Generally, biofilm program should be reserved for parents with experience in giving antimicrobials to their kids.

• Step #1 – Lysis (breakdown) and Detachment of Polysaccharides.• plus additional interventions, i.e. Stevia
• Step #2 – Attacking the Microbes
• Step #3 – Cleaning Up

YOUR LOGO
Step #1 – Lysis & Detachment
• Enzymes (good option is Interfase Plus)• Another option = Interfase (w/o EDTA) for sensitive
individuals.
• NaEDTA (helps to bind minerals in biofilm)
• Taken on empty stomach 30 minutes before or 90 minutes after meals (breakfast, lunch, dinner).
• Polysaccharides = complex sugars with mineral linkages – iron, calcium, magnesium.
• Take minimally 30 minutes before Step #2
Biofilm Enzymes - example
YOUR LOGO
Additional Consideration to Enhance Biofilm Breakdown
• Stevia – is a sugar substitute and sweetener taken from the plant species Stevia rebaudiana.
• Reported to help in the degradation of biofilms by opening up fluid channels which allows for antimicrobial remedies to penetrate deeper into the biofilm matrix.
• Good options for kids as it can be added to dilute juice.
• Full dose = 7 drops (reported for Lyme?). For kids, consider using 2 to 4 drops on empty stomach.
YOUR LOGO
Step #2 – Attacking the Microbes
• Antibiotics – Flagyl, Vancomycin, Alinia, Penicillin, Zithromax, etc.
• Antifungals – Nystatin, Diflucan, Sporanox, Lamisil
• Natural Remedies:• Biocidin, Oil of Oregano, Olive Leaf Extract, Uva Ursi,
Caprylic Acid, Allimax, Candida Yeast Packet, other individual or combination botanicals.
• These are taken approximately 30 minutes after Step #1 biofilm enzyme product is administered.

Additional Biofilm Remedies
• Lactoferrin – binds to iron which is an important mineral for candida and bacteria.
• Essential plant oils, i.e. Biocidin – oils reported to turn off ‘quorum sensing’ and pump system, and disrupt biofilm formation.
• Curcumin (turmeric) + Quercetin Complex –Curcumin aides in decreasing inflammation, liver and colon support; whereas the Quercetin helps with decreasing excess histamine production.

Step #3 – Cleaning Up
• Give remedies 60 to 90 minutes after Step #2
• Activated Charcoal – ½ to 2 capsules
• Fiber, i.e. TruFiber, Apple Pectin, Ground Flax Seeds – ½ to 1 tablespoon.
The main reason for the Activated Charcoal (AC) is to bind “die-off” toxins generated by Step #1 and #2. If individual is not experiencing “die-off” than AC is not absolutely necessary. However, a fiber product is worthwhile to keep the stool
consistency bulky and prevent against constipation.
