“…The role of natural products in drug production is increasing, not only when biologically active compounds are used directly as therapeutic drugs, but also when used as raw materials for drug synthesis, or as a model the base is used for new biologically active compounds [13][14][15] . Studies show that only about 10% of the 250,000 species of plants studied worldwide 16 . Therefore, the use of herbal drugs as an alternative to chemical drugs and antibiotics was investigated in many research studies [17][18][19] .…”

The recent increasing use of artificial antibiotics has prompted an expansion in resistant strains and high site reactions. Medicinal plants have for quite some time been utilized as traditional medicine to treat pathogenic bacteria. In such manner, consistently numerous scientists are sending a range of plant’s secondary compounds to the customer advertise for the treatment of human illnesses. Accordingly, the distinguishing proof of plant spices with antimicrobial impacts can assist with delivering new medications with a wide range of impacts. The aim of the present research was to examine the ability of ethanolic leaves extracts of Rosmarinus officinalis plant as antibacterial agent against the Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli. The zone of inhibition increased with increase in concentration of the test solution. Higher activity of ethanolic extract was found against S. aureus (2.4 cm) than E. coli (1.8 cm). In addition, the repetitive element PCR (Rep-PCR) significantly showed that several genetic numbers of polymorphic bands were observed in S. aureus and E. coli treated bacteria with leaves extracts and not observed in the control. These results indicate that these extracts have a genotoxicity effect on the two bacterial genomes. The obtained results demonstrate that R. officinalis can be used as a potential source of antibacterial and genotoxicity factors.

“…Furthermore, the rosemary did not show any effect on bacterial growth, and this is in agreement with Jawad et al that extract of rosemary showed a wide range of antibacterial activity against positive and negative bacteria like Escherichia coli [37]. The extract of rosemary contains phenols which have the ability of inhibition on the cell walls and cell membranes synthesis, nucleic acid metabolism and on the Gram-positive and Gram-negative bacteria and wide range on bacteria and fungi inhibition.…”

Objective: The aim is to estimate the effect of curcumin and rosemary as antibacterial agents among dental caries cases. Methods: Samples of saliva were randomly collected from 40 patients in Al-Furat General Hospital who attended the hospital from July to September 2018. Swabs were cultured on blood agar at 37°C for 24 h and then subcultured in mannitol salt agar and trypticase soy broth at 37°C for 24 h. Different concentrations of aqueous extract curcumin solution (0.1, 0.3, 0.5, and 1 mg/ml) and rosemary solution (1 g/ml) were prepared and added to the bacterial culture. Later, minimum inhibition zones of the bacterial cultures were determined. Results: The results showed that there were 25 cases of Streptococcus mutans, 10 cases of Staphylococcus aureus, 3 cases of anaerobic bacteria, and 2 cases of normal flora among 40 culturing swabs of bacteria. Aqueous extract of curcumin showed antibacterial effect with concentrations (0.1, 0.3, 0.5, and 1 mg/ml) against oral bacteria; nevertheless, these bacteria were resistant to the aqueous extract of rosemary with concentration 1 g/ml. Conclusion: It can be concluded that curcumin can be an effective antibacterial agent against dental caries disease and its effect increases positively in relation to its concentration. On the other hand, rosemary with 1 g/ml concentration did not show any effect on oral bacteria.

“…The difference in this regard could be due to the active binding sites of the bioactive ingredients of EO with the applied surfactant, as well as the inhibition of bringing the EO into the proximity of the bacterial cell membrane [29]. On the other hand, the results of the present study demonstrated that P. aeruginosa had lower sensitivity to REO, which is in line with the findings of Jawad et al (2018) and Thanh et al (2017) [18,30].…”

Journal homepage: www.zums.ac.ir/jhehp Background: The purpose of this study was to determine the effect of rosemary essential oil (REO) nanoemulsion against some important food borne pathogens. Methods: Antibacterial effects of REO and REO nanoemulsion were determined using Agar disc diffusion, Broth microdilution and Steam phase diffusion methods against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Shewanella SP, Listeria monocytogenes and Salmonella enteritidis. Results: Antibacterial effect of REO and REO nanoemulsion was increased with concentration enhancing of REO. There was no significant antibacterial activity in the effectiveness of nanoemulsion on the studied bacteria in comparison with REO in both disk diffusion and steam phase diffusion methods. MIC and MBC analysis of REO and prepared REO nanoemulsion showed that REO and its nanoemulsion have inhibited all studied bacteria. REO showed better inhibitory effects. REO and nanoemulsion of rosemary essential oil have the greatest effect on Shewanella SP., L. monocytogenes, S. aureus, S.enteritidis, E. coli and P. aeruginosa, respectively. Conclusion: In total, it can be said that REO and its nanoemulsion are desirable to inhibit the growth of food borne pathogens and can be a good choice as antimicrobial agents in food industry to enhance safety and extend foods' shelf life.
