Biofilm & motility studies on food borne pathogens under the treatmnet of silver Nanoparticles

Foodborne illness (sometimes called "foodborne disease," "foodborne infection," or "food poisoning) is a common, costly—yet preventable—public health problem. Many different disease-causing microbes, or pathogens, can contaminate foods, so there are many different foodborne infections. In addition, poisonous chemicals, or other harmful substances can cause foodborne diseases if they are present in food. The present study was focussed to check the effect of silver nano particles on the food borne pathogens. The study was aimed to screen the activity of the nanoparticles on the bacterila growth and its biofilm forming ability. Motility ability of the species was also assayed by capillary method. Percent inhibition of nanopartciles on the food borne pathogens was dose dependent. There was no much difference between the species. But with increasing concentrations of the nanoparticles the effect was found to be significant. The effect was found to be more at 500μg/ml. Biofilm inhibition assay was done under the treatment of nanopartciles on the food borne pathogens. This assay was also found to be dose dependent. There was no much difference between the species. But with increasing concentrations of the nanoparticles the effect was found to be significant. The effect was found to be more at 500μg/ml. The effect was significant and dose significant. There was no much difference between the species. But with increasing concentrations of the nanoparticles the effect was found to be significant. The effect was found to be more at 500μg/ml. The motility behaviour of the isolates was confirmed and was found to more with increasing time. The number of colonies was found to be more with the increase in time.
