  1. School of Earth & Space Exploration Antibacterial Clays D. D. Eberl, Lynda B. Williams, David Metge and Keith Morrison USGS and Arizona State University Research funded by National Institutes of Health National Center for Complementary and Alternative Medicine

  2. French Green Clays Heal Buruli ulcer From http://burulibusters.com

  3. Day 1

  4. Day 2

  5. Day 103

  6. Could this be the result of a bite ? Lethocerus Buruli ulcer prevails in women and children who forage for food in swamps. These common aquatic bugs may carry the Mycobacterium ulcerans that attack skin cells years after the bite occurs.

  7. Argicur Argiletz

  8. Clays tested against E. coli and S. aureus “Healing Clays” Pascalite (Wy) Redmond (UT) Black Manna (OR) ‘Dead Sea’- IL black clay (?)

  9. Killing efficiency of some ‘antibacterial clays’ OMT 07 Walker 07 Argiletz 02 Argicur 02

  10. 1.0 µm TEM on E.coli after Critical Point Drying E. coli after 1hrs in AMT leachate 0.5 µm E. coli after 24hrs in AMT leachate

  11. Nano-Secondary Ion Mass Spectrometry E. coli treated with OMT clay (Morrison, Misra, Williams, Nature, Sci. Rep. 2016)

  12. Requirements for antibacterial clay • Source for iron (e.g., pyrite) • Source for aluminum (e.g., clay or feldspar) • pH<4.2 (weathering of pyrite) or >10 • Eh = 450 to 800mV (to stabilize Fe2+) • Swelling clay with CEC to buffer chemistry

  13. Changes in oxidation state produce the observed mineralogy

  14. Conclusion • The Oregon clay is effective at killing a broad spectrum of pathogenic bacteria, including antibiotic resistant strains (e.g., MRSA). • Experiment with the Oregon clay at your own risk. Please report your results to: antibacterialclay@gmail.com • High tech instruments (e.g., NanoSIMS) reveal the science behind a low tech but effective cure • For more information please consult our website: www.AntibacterialClay.net
