Abstract

As there are a lot of antibacterial and anti-fungal resistant pathogens, researchers attempt to substitute antimicrobial drugs with various medical plants and novel nanoparticles. The present study was conducted to characterize antimicrobial activities of Euphorbia prostrata and Pelargonium graveolens extract alone and in combination with Mn-Ni@Fe3O4-NPs & Mn: Fe (OH)3-NPs on the DNA cleavage of E. coli and also Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Aspergillus oryzae, and Candida albicans. The effects of antimicrobial activities on above scenarios were evaluated using disc diffusion, MIC, MBC, and E. coli DNA electrophoresis methods. The results showed that the effects of antibacterial assay values of Euphorbia prostrata & Mn: Fe(OH)3 was 21.00 mm for E. coli and while it was 19.5 mm for Euphorbia prostrata & Mn-Ni@Fe3O4 against Pseudomonas aeruginosa at a concentration of 100mg/mL. The highest level of DNA cleavage was seen in mixed of Euphorbia prostrata & Mn: Fe(OH)3 nanoparticles. In conclusion, the combination of Euphorbia prostrata and Pelargonium graveolens extracts with nanostructures showed synergic effects on eliminating the bacteria via DNA destruction and others mechanisms. Moreover, the synergistic effect of nanoparticles with plant extracts seems to bring about new choices for the treatment of infectious diseases.
