background: despite the discovery of numerous antibiotics, drug resistance still remains as a major problem. therefore, it is important to introduce and replace new sources of drug such as medicinal plants with antimicrobial properties. objective: the genus clematis (ranunculaceae family) has six species in iran. aerial parts of clematis have been used to cure fever and chronic diseases such as...

The purpose of the present study to examine the antibacterial and cytotoxic properties of ethanol extract of leaves of Mikania cordata (Burm.f.) B.L. Robinson. To determine antibacterial activities, the extract was tested against four Gram positive and six Gram negative bacteria at three concentrations (500, 800, 1000 μg disc(-1)) through disc diffusion method. The extract showed moderate antib...

To make use of nano-sized particles for biomedical applications such nanomedicines for different diseases, it is important to study how nanoparticles behave when they interact with microorganisms. In the present study, we investigated the antibacterial performance of chromium oxide nanoparticles (Cr3O4 NPs) against two gram negative bacterial strains, Escherichia coli, and Pseudomonas aeruginos...

Bacteriolyses of bacterial cell walls by zinc (II) ions on the basis of the results of halo antibacterial susceptibility tests were investigated for the nitrate and the sulfate solutions. From the results obtained by halo antibacterial tests of sulfate solutions against Staphylococcus epidermidis, the antibacterial order is Zn2+>Cu2+>Ag+>Al3+, in which Zn2+ ions indicate the highest antibacteri...

We examined whether household use of antibacterial cleaning and hygiene products is an emerging risk factor for carriage of antimicrobial drug-resistant bacteria on hands of household members. Households (N = 224) were randomized to use of antibacterial or nonantibacterial cleaning and hygiene products for 1 year. Logistic regression was used to assess the influence of antibacterial product use...

Polyunsaturated fatty acids, such as eicosapentaenoic acid (EPA; C20:5n-3), are attracting interest as possible new topical antibacterial agents, particularly due to their potency and perceived safety. However, relatively little is known of the underlying mechanism of antibacterial action of EPA or whether bacteria can develop resistance quickly against this or similar compounds. Therefore, the...
