Introduce some basic concepts of bacterial genetics. Botox® is made from Botulinum Toxin Type A, a protein produced by bacterium Clostridium. For the purposes of improving the appearance of wrinkles, small doses of the toxin are injected into the affected muscles blocking the release of a chemical that would otherwise signal the muscle to contract. The toxin thus paralyzes or weakens the injected muscle. The treatment usually begins to work within 24 to 48 hours and can last up to 4 months. The Food and Drug Administration (FDA) approved the cosmetic use of Botulinum Toxin Type A for the temporary relief of moderate to severe frown lines between the brow and recommends that the procedure be preformed no more frequently than once every 3 months. . 1.

The findings offer clues to the evolutionary origins of the potent toxins that enable bacterial pathogens to cause human diseases such as cholera and diphtheria. .. Research Details. Strategies for controlling pathogen growth There are a number of strategies for the control of pathogens in sh and shery products. They include: ontrolling the level of acidity (pH) in the E.
