In vitro assessment of the antimicrobial activity of silver and zinc oxide nanoparticles against fish pathogens.

Background: Antibiotic resistance is a global issue that threatens public health. The excessive use of antibiotics contributes to this problem as the genes of antibiotic resistance can be transferred between the bacteria in humans, animals and aquatic organisms. Metallic nanoparticles could serve as future substitutes for some conventional antibiotics because of their antimicrobial activity.

Evaluation of hepatotoxic and genotoxic potential of silver nanoparticles in albino rats.

Unlabelled: Silver nanoparticles (AgNPs) have wide medical applications regarding their antimicrobial effects. They are applied also in appliances such as refrigerators and washing machines. For assessment of toxicological potential of silver nanoparticles 20 mature female albino rats were divided into four groups (five rats per each).
