ANTIBIOTIC SENSITIVITY OF GOLD AND SILVER NANOPARTICLES AGAINST ENTEROCOCCAL PATHOGENS
Abstract
Although disinfection methods currently used in drinking water treatment can effectively control microbial pathogens, research in the past few decades have revealed a dilemma between effective disinfection and formation of harmful and to consider innovative approaches that enhance the effectiveness. With the rapid advancement of nanoscience and nanotechnology, detailed knowledge of interactions between engineered nanomaterials and cells, tissues and organisms has become increasingly important, especially in regard to possible hazards to human health. The study was mainly designed to study the effect of silver and gold nanoparticles against the enterococcal pathogens. The organisms were also tested against the antibiotics to prove of their susceptibility towards the drugs. The enterococcal pathogens studied here showed a positive response for all the drugs used. The silver and gold nano particles are studied in this context to prove of their effect on the bacterial pathogens. Gold and silver particles are studied separately and are found to show some significant effect on the growth of bacteria. The pathogens studied showed susceptibility towards both the particles (gold and silver). And the effect of the nano particles was completely dose dependent i.e., the effect was found to be more at higher concentration. All effects were statistically significant at the 0.05 significance level. There was a significant effect of the nano particles (gold and silver) among the four different concentrations remembered at the p < 0.05 level. Gold nano particles showed a significance to the concentration [F(1,7) = 13.36364, p = 0.035353].
