“…The results of the macrodilution tests showed that silver nanoparticles have a good antimicrobial effect against S. aureus at low concentrations, which is consistent with the results of recent researches performed by Alizadeh et al ( 22 ) and Bokaeian et al ( 23 ). Also, the microdilution test showed the antibacterial activity of plant peptide MBP-1 against S. aureus .…”

Background:Wound infection is a common problem in hospitals and is typically caused by the antibiotic-resistant Staphylococcus aureus, which is a major pathogen for skin and soft tissue infections worldwide.Objectives:The aim of this study was to investigate the synergistic antibacterial effect of plant peptide MBP-1 and silver nanoparticles on infected wounds caused by S. aureus.Materials and Methods:The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of MBP-1 and silver nanoparticles both on their own and in combination form were determined against S. aureus via macrodilution and microdilution methods. The synergistic antibacterial effect of silver nanoparticles and MBP-1 was investigated on infected wounds caused by S. aureus in a mouse model.Results:The MIC and MBC of MBP-1 were found to be 0.6 and 0.7 mg/mL, respectively. MIC and MBC of silver nanoparticles were determined to be 6.25 and 12.5 mg/L, respectively. MIC and MBC of the silver nanoparticles and MBP-1 combination were found to be 3.125 mg/mL, 0.5 mg/L; and 6.25 mg/mL, 0.6 mg/L, respectively. The infected wound healed properly after the combined use of MBP-1 and silver nanoparticles.Conclusions:The synergistic effect was found on the healing of infected wounds caused by S. aureus by using an MBP-1 and silver nanoparticles combination in a mouse model.

“…Silver nanoparticles have powerful antimicrobial properties and it is recorded to have an antimicrobial effect against S. aureus at concentrations (100 μg/ml and 200μg/ml). These results were in accordance with several authors worldwide [23][24][25] who stated tha AgNPs exhibited antimicrobial1activity against S. aureus at a concentration (100 μg/ml), While [7] stated that S .aureus growth was inhibited at higher concentration reached 800 μg/ml AgNPs. The bacterial growth inhibition by AgNPs was found to be concentration-dependent as the antibacterial activity was elevated with the increase-of (AgNPs) concentration.…”

Silver nanoparticles (AgNPs) are of special concern as a result of their unique chemical, physical and biological characteristics. It has become an attractive alternative to antibiotics due to their broad-spectrum antimicrobial activity.The study aimed to determine the antibacterial activity of AgNPs against S. aureus bacteria and the effect of AgNPs on the viability of normal cell line (vero cell). A total of 70 clinical samples (wound and vagina swab, stool and urine) were used in this study. Bacterial isolates were subjected to the microscopical, cultural and biochemical evaluation.AgNPs were prepared and checked for their antimicrobial activity by the use of various concentrations employing agar dilution method. In addition, the effect of different concentrations of AgNps on a viability of vero cells was examined. The results showed that out of 70 clinical samples, 11 (15.7%) isolates were Staphylococcus aureus.AgNps showed high activity against S. aureus at concentrations (100 μg/ml and 200μg/ml). It was found that there was no effect of AgNPs on the viability of the normal vero cells at (≤ 250 μg/ml) concentration, but they have cytotoxic effect on the viability of the these cells at high concentrations. This study concluded that AgNPs possess good antimicrobial activity and the concentrations that maintain the cell viability could be used as an alternative therapy to treat S. aureus infections.

Background and Objectives: The aim of this study was to investigate the effect of ethanol extract of green tea on biofilm formation of Staphylococcus aureus. Methods: Staphylococcus aureus samples were obtained from hospital sources and plant extracts; green tea was made using the rotary. The minimum inhibitory concentration was determined using the microdilution method. Inhibition of biofilm formation was determined by using a microplate. Results:The results of this study showed that the greatest resistance was to the antibiotics penicillin (88.2%) and erythromycin (82.4%) and the least resistance to the antibiotic Amikacin (76/11%), respectively. The results of the effect of green tea extract showed the lowest inhibitory concentration (MIC) is equal to 0.3 milligrams per milliliter, which is a strain on the inhibitory concentration, and the highest concentration (MBC) MBC resistant Staphylococcus aureus equal to 20 milligrams per milliliter, which is controlled unidirectional. The results of green tea extract effects on biofilm showed that with increasing concentrations of less biofilm formation the biofilm formation has been much lower concentration of the extract. Conclusions:The results of this study indicate good effects of green tea extract to inhibit biofilm formation of Staphylococcus aureus, which can be used to treat infections caused by these bacteria's.
