Bacterial cells have membranes that are negatively charged, and the EquiCare anti-microbial agents are positively charged compounds. Negatively charged objects attract positively charged objects, and positively charged objects attract negatively charged objects, and when these charges come together they attach to each other. When the EquiCare molecule attaches to the bacterial cell membrane, large holes are formed in the membrane. A rapid exchange of ions, such as sodium, potassium, chloride, and other mineral ions pass through these holes. These ions move in two different directions: from the inside of the cell to the outside and from the outside of the cell back into the interior of the cell. This exchange of ions destroys the cell membrane, and destroys the internal balance of bacterial and fungal cells. This mechanism is how EquiCare stops fungal and bacterial infections.

Animal and human cells are neutral or positively charged. When the anti-microbial compounds in EquiCare come near a neutral or positively charged membrane it is repelled. It cannot attach itself to the membrane, or enter into these cells, or damage these cells. The electrostatic charge on the EquiCare anti-microbial agents makes EquiCare selectively toxic to bacterial and fungal cells, and harmless to the surrounding tissue.
