Nadi Ergenc Contaminated water, poor sanitation and low hygienic standards are the leading cause of global disease. Plastic articles are increasingly gaining on importance in our daily live. The primary target of microbial attack is not the polymeric material but residual nutrients found in dead spots, surface roughness or microcracks. These areas provide ideal conditions for microbial growth as they can not be reached by application of standard cleaning procedures. Mo. The same elements are found in water, sweat, skin residues, dirt and organic waste thus being the nutrients for bacteria.
Nourished bacteria don t grow bigger but multiply instead.
This is the reason for rapid spread of bacteria. Not all bacteria are a problem, but certain types and strains can be harmful or can generate irritant or toxic substances. All these microbiological processes can take place in microhabitats on plastic surfaces. The combination of high compatibility with the polymeric substrate and the high level of activity ensures long lasting efficacy typically for the useful life of the article. The Agar Diffusion Test is one way to analyze the efficacy of an antimicrobial additive incorporated into plastics.
