4. 2 © 2007 MaxSpray International Corporation Kill Attacking Amoebae ScienceDaily (July 25, 2008) — Bacteria rarely come as loners; more often they grow in crowds and squat on surfaces where they form a community together. These so-called biofilms develop on any surface that bacteria can attach themselves to. The dilemma we face is that neither disinfectants and antibiotics, nor phagocytes and our immune system can destroy these biofilms. Environmental Professional Contracting Services  Amoebae normally attack and kill harmful pathogens  Pathogens have become Resistant (biofilm bacteria use chemical weapons to defend themselves.)  They clump together and build a slimy fortress of defense  Effective in the presence of all amoebae, killing them or causing them to become de-activated  Athletic Facilities  Hospitals  Implants  Catheters  Surfaces  Surgical equipment Common Problem Areas

16. 14 © 2007 MaxSpray International Corporation Overview Antimicrobial agents are used to kill or limit growth of microorganisms. ÆGIS Microbe Shield™, an antimicrobial agent composed of a silane quaternary ammonium salt, is featured for its durability and efficacy against both gram-negative and gram-positive bacteria. This research studied the effectiveness of the antimicrobial agent as a treatment for cotton fabric. Cotton fabric samples were coated with the antimicrobial agent, then tested against three species of bacteria. The samples were shaken in a bacterial solution to allow contact with the microbes, and the number of viable bacteria were counted. The data were compared to the numbers of bacteria with untreated fabric. This research reveals that the antimicrobial agent reduced the numbers of bacteria exposed to the treated cotton fabric.

17. 15 © 2007 MaxSpray International Corporation Environmental Professional Contracting Services Research  The three types of bacteria were Escherichia coli, Staphylococcus epidermidis, and Bacillus subtilus. For each test, the bacteria were grown in Tryptic Soy Broth (TSB) for eighteen hours at room temperature. The bacteria were diluted in 0.003M KH 2 PO 4 to 72 percent transmission using a Vitek Colorimeter. For testing, the bacteria were diluted 1:1000 to 1.5-3.0 x 10 5 cfu/mL. Then, 50mL aliquots of the diluted bacteria were distributed into sterile 250mL flasks.  The number of bacteria were determined by the pour plate method using Tryptic Soy Agar (TSA). The control was plated at “0” contact time. The nine flasks were agitated in a reciprocal shaker at 120 RPM. After one hour, all bacteria samples were plated and incubated for 24 hours at 35°C.

18. 16 © 2007 MaxSpray International Corporation Results Graph 1: Comparison of all pure cultures used with and without the antimicrobial agent. It was discovered that the antimicrobial agent did exhibit the ability to kill the three species of bacteria.
