Many patients with autistic symptoms have persistent dysbiosis. Treatment of GI issues often alleviates the symptoms we call autism. Hypothesis:
Patients with autism, who have toxic metal burdens and toxic chemical burdens are likely to grow resistant organisms in their GI tract. This resistance to treatment is perpetuated by the production of biofilms. Treatment of biofilms will help to eradicate dysbiotic flora and improve the symptoms we call autism.

What is Biofilm?
 A biofilm is a collection of microbial
communities enclosed by a matrix of extracellular polymeric substance (EPS) and separated by a network of open water channels. manmade and natural surfaces, such as metals and teeth, typically at a liquid-solid interface . Their architecture is an optimal environment for cell-cell interactions, including the intercellular exchange of genetic material, communication signals, and metabolites, which enables diffusion of necessary nutrients to the biofilm community. negatively charged polysaccharide substance, held together with positively charged metal ions (calcium, magnesium, and iron). biofilm are embedded protects them from UV exposure, metal toxicity, acid exposure, dehydration salinity,

5 stages of biofilm development.
Stage 1, initial attachment; stage 2, irreversible
attachment; stage 3, maturation I; stage 4, maturation II; stage 5, dispersion.
Each stage of development in the diagram is paired
with a photomicrograph of a developing P. aeruginosa biofilm.
Where do they grow?
•Biofilm formation appears common near polluted and toxic areas and environments. Account for the majority of all microbial infections of the human body.

Device-related infections, intravenous catheters, joint prostheses

•Human body – Mouth, teeth, pancreaticbiliary tracts, lungs, sinuses, adenoids, tonsils and the intestinal tract….
Why are they so difficult to treat?
•Remarkably difficult to treat with antimicrobials, resistant to doses of antimicrobials 100- to 1000-fold over the minimum lethal dose for microbes outside of biofilms. •Antibiotics do not penetrate the polysaccharide matrix. •Highly resistant to both immunological and nonspecific defense mechanisms of the body. •Difficult to diagnose, difficult to culture. •Microbes impart genetic material to one another to maintain resistance. •Colonies communicate with one another through the use of quorum sensing molecules. •Colonies fail to express OMP (outer membrane

Probiotics to Prevent the Need For, and Augment the Use Of, Antibiotics Can J Infect Dis Med Microbiol. 2006 Sep
Gregor Reid, BSc, PhD MBA
Reduce the risk of antibiotic-induced super
infections in the gut and the vagina; Secrete antibacterial substances that lower pathogenic bacterial populations locally and at distant mucosal sites, and disrupt biofilms, making it easier for antibiotics to function; Enhance generalized mucosal immunity, which in turn aids in the eradication of the organisms at the mucosal site.
Microbial biofilms in the human gastrointestinal tract.
J Appl Microbiol. 2007 May;102(5):1187-96. Macfarlane S, Dillon JF.
There is mounting interest in mucosal biofilms in the colon, especially with respect to their role in inflammatory bowel disease. Because bacteria growing in biofilms are more resistant to antibiotics than unattached organisms, it is often difficult to modify the structure and composition of these communities, or to eradicate them from the body. However, recent work has shown that there is considerable potential to alter the species composition of mucosal biofilms in a beneficial way using synbiotics.
The Efficacy of EDTA Against Biofilm Bacteria
(Kim, 2005)
Biofilms = complex communities of micro-
organisms attached to surfaces held together by EPS (extracellular polysaccharides, that are negatively charged and held together by positively charged cations, specifically Fe2+, Ca2+, and Mg2+. EDTA complexes with cations in the extracellular matrix. Neither Vancomycin or EDTA alone detached Staph biofilm. EDTA plus Vancomycin together caused biomass
Chelator-Induced Dispersal and Killing of Pseudomonas aeruginosa Cells in a Biofilm (Banin, 2005)
EDTA is a potent Pseudomonas biofilm disrupter. 1000x killing when EDTA combined with Gentamicin. EDTA causes dispersal and killing of biofilm cells. Ca, Fe, and Mg protect biofilm. When Ca or Fe are added, killing and detachment are
completely blocked.
EDTA as an Adjuct Antifungal Agent for Invasive Pulmonary Aspergillosis in a Rodent Model
(Hachem, 2006)
Immunosuppressed rats infected with Aspergillus
who were treated with an antifungal drug and EDTA in combination had less severe disease and greater survival
EDTA acts like an antifungal –enhancing agent Absence of direct toxic effect of EDTA, no tissue
damage associated with EDTA
Iron Chelating Compounds
Outer membrane proteins(OMP) are
expressed when iron is restricted. If OMP are not expressed, the immune system is not alerted appropriately, and can not illicit a normal immune response.
Transferrin and Lactoferrin
Synthesized by host to inhibit bacterial growth
by sequestering free Iron. Pathogenic bacteria secrete iron chelators (siderophores) to compete with transferrin and lactoferrin for Iron.
A Component of Innate Immunity Prevents Bacterial Biofilm Development.
Nature. 2002 May 30;417(6888):552-5. Singh PK, Parsek MR, Greenberg EP, Welsh MJ. Antimicrobial factors form one arm of the innate immune system, which protects mucosal surfaces from bacterial infection. These factors can rapidly kill bacteria deposited on mucosal surfaces and prevent acute invasive infections. In many chronic infections, however, bacteria live in biofilms, which are distinct, matrixencased communities specialized for surface persistence. The transition from a freeliving, independent existence to a biofilm lifestyle can be devastating, because biofilms notoriously resist killing by host defence mechanisms and antibiotics. We hypothesized that the innate immune system possesses specific activity to protect against biofilm infections.
Here we show that lactoferrin, a ubiquitous and abundant constituent of human external secretions, blocks biofilm development by
the opportunistic pathogen Pseudomonas aeruginosa. This occurs at lactoferrin concentrations below those that kill or prevent growth
. By chelating iron, lactoferrin stimulates twitching, a specialized form of surface motility, causing the bacteria to wander across the surface instead of forming cell clusters and biofilms. These findings reveal a specific anti-biofilm
defence mechanism acting at a critical juncture in biofilm development, the time bacteria stop roaming as individuals and aggregate into durable communities.

Enzymatic Degradation
Dispersing biofilms with engineered enzymatic bacteriophage.
Proc Natl Acad Sci U S A. 2007 Jul 3;104(27):11197-202. Epub 2007 Jun 25.  Lu TK, Collins JJ.   Synthetic biology involves the engineering of biological organisms by using modular and generalizable designs with the ultimate goal of developing useful solutions to realworld problems. One such problem involves bacterial biofilms, which are crucial in the pathogenesis of many clinically important infections and are difficult to eradicate because they exhibit resistance to antimicrobial treatments and removal by host
we engineered bacteriophage to express a biofilmdegrading enzyme during infection to simultaneously attack the bacterial cells in the biofilm and the biofilm matrix, which is composed of extracellular polymeric substances. We show that the efficacy of biofilm removal by this two-pronged enzymatic bacteriophage strategy is significantly greater than that of
immune systems. To address this issue,
Biofilm formation of Staphylococcus aureus strains isolated from impetigo and furuncle: role of fibrinogen and fibrin.
J Dermatol Sci. 1997 Nov Akiyama H, Ueda M, Kanzaki H, Tada J, Arata J.
The formation of membranous structure (thickness from the plastic tissue-culture coverslip (hematoxylin-eosin) > 1 mm; periodic acid-Schiff-positive) was more prominent with Staphylococcus aureus (S. aureus) strains isolated from impetigo (coagulase types I.V origin) than with S. aureus strains isolated from furuncle (coagulase type IV origin) (P < 0.05) in the plastic tissue-culture coverslip in human plasma after 72 h. Attachment of S. aureus cells to a plastic tissue-culture coverslip was more marked in 0-3% fibrinogen/tryptic soy broth (TSB) than in plasma (P < 0.05). The formation of the membranous structure was observed on the plastic tissue-culture coverslip with 0.3%
Electron microscopy revealed abundant fibrin around S. aureus cells at
fibrinogen/human serum but not with 0.3% fibrinogen + 5% glucose/TSB. 4 h and Ruthenium red-positive materials increased at 24 and 72 h in plasma. Staphylococcus aureus cell attachment to the plastic tissue-culture coverslip in plasma decreased by addition of levofloxacin (LVFX) at 1/2 minimum inhibitory concentration (MIC) and clarithromycin (CAM) at 1/4 MIC. Polysaccharide production of S. aureus cells on the plastic tissue-culture coverslip in plasma decreased with the addition of CAM at
Fibrinogen is closely related to initiation of infection but biofilm formation requires the conversion of fibrinogen to fibrin. Thus, attachment of S. aureus cells to the plastic tissue-culture coverslip,

Proteolytic enzymes: a new treatment strategy for prosthetic infections?
Antimicrob Agents Chemother. 1993 Dec Selan L, Berlutti F, Passariello C, Comodi-Ballanti MR, Thaller MC.
Among the different mechanisms of bacterial resistance to antimicrobial agents that have been studied, biofilm formation is one of the most widespread. This mechanism is frequently the cause of failure in the treatment of prosthetic device infections, and several attempts have been made to develop molecules and protocols that are able to inhibit biofilm-embedded bacteria. We present data suggesting the possibility that proteolytic enzymes could significantly enhance the activities of antibiotics against biofilms. Antibiotic susceptibility tests on both planktonic and sessile cultures, studies on the dynamics of colonization of 10 biofilm-forming isolates, and then bioluminescence and scanning electron microscopy under seven different
Enhancement of the Fibrinolytic Activity in Plasma by Oral Administration of Nattokinase.
Acta Haematol. 1990;84(3):139-43 Sumi H, Hamada H, Nakanishi K, Hiratani H.
The existence of a potent fibrinolytic enzyme (nattokinase, NK) in the traditional fermented food called 'natto', was reported by us previously. It was confirmed that oral administration of NK (or natto) produced a mild and
frequent enhancement of the fibrinolytic activity in the plasma, as indicated by the fibrinolytic parameters, and the production of tissue plasminogen activator. NK capsules were also
administered orally to dogs with experimentally induced thrombosis, and lysis of the thrombi was observed by angiography. The results obtained suggest that NK represents a possible drug for use not only in the treatment
Dentists understand biofilm!
“Normal mouthwashes can only clean the surface, which is why bad breath returns quickly and gum disease is a constant problem. With the new patented technology in Biotene PBF mouthwash, you can dissolve the biofilm, expose hidden bacteria colonies and kill germs. In addition, Biotene PBF contains the proven LP3 salivary enzyme system to strengthen the body’s antibacterial action, dissolving biofilm and inhibiting excessive bacteria – maintaining a healthy oral balance.”
Chitosans and Biofilm
Effects of chitosans with different molecular weights on Streptococcus sanguis biofilm
Ma R, Zhu M, Liu Z.
Streptococcus sanguis biofilm was formed on saliva-coated glass (SCG) in a flow culture system, then exposed to 2% chitosans with different molecular weights (5 cps, 80 cps, 600 cps) for 3, 10, 30 minutes. Confocal laser scanning microscope and Vital/Dead fluorescent staining technique (vital stained green, dead stained red) were combined to observe the biofilm thickness, bacterial density. Analysis of variance was used for PMID: RESULTS:
the biofilm thickness and bacterial density reduced significantly after treatment with 2% chitosan. Low molecular weight chitosan seems most effective at detaching biofilms. Antimicrobial effects of chitosans and chitooligosaccharides, upon
