A well known anti-cancer lignan arctiin has not been studied for its antibacterial activity based on our literature search. In the present work, the antibacterial and general toxicity of the arctiin from the seeds of Centaurea sclerolepis is studied. Arctiin did not show any significant antibacterial activity against both Gram-positive and Gram-negative bacteria when compared with the positive ...

Silver is considered as antibacterial agent with well-known mode of action and bacterial resistance against it is well described. The development of nanotechnology provided different methods for the modification of the chemical and physical structure of silver, which may increase its antibacterial potential. The physico-chemical properties of silver nanoparticles and their interaction with livi...

Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...

Background: Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP again...

Aim Silver nanoparticles have long been used as potent antibacterial agents. However, toxicity concerns of silver nanoparticles have limited their successful clinical applications. Hence, development of silver-based novel biocompatible nanomaterials for antibacterial applications is a challenging task. Materials & methods Accordingly, in this work, we synthesized a biocompatible silver-based ...

Titanium implants have been widely used for many medical applications, but bacterial infection after implant surgery remains one of the most common and intractable complications. To this end, long-term antibacterial ability of the implant surface is highly desirable to prevent implant-associated infection. In this study, a novel antibacterial coating containing a new antibacterial agent, (Z-)-4...

Three mouthwashes Gengigel, Oradex and Salviathymol N, were tested using experimental microorganisms included Fusobacterium nucleatum, Streptococcus mitis, Streptococcus constellatus, Eikenella corrodens and dental plaque. Staphylococcus aureus and Escherichia coli were used as internal controls. Antibacterial activity was done by diffusion test. Minimum inhibitory concentration test and assess...

background and objective: early determination of antibacterial susceptibility increases the success of therapy, decreases unnecessary use of antibacterial agents and side-effects, and lowers the overall healthcare cost. materials and methods: a rapid colorimetric method for antibacterial susceptibility testing named qui-sensitest (inovative biotechnology organization, istanbul, turkey) was eval...

Methanol, chloroform, petroleum ether and aqueous extract of Crotalaria burhia (whole plant) were investigated for their antibacterial activity against Staphylococcus aureus using cup plate agar diffusion method. The 4 extracts tested, the methanol extract presented the best results. Various investigations like physicochemical standards, preliminary phytochemical screening of the plant was carr...

The plant Spondias pinnata (Linn. f.) Kurz belonging to Anacardiaceae family, is used as a medicinal agent in Bangladesh. In the present investigation, attempt was undertaken to study the antibacterial potency and cytotoxic activity of 80% ethanol extract of its fruit. The antibacterial activity was performed by the disc diffusion method and cytotoxicity was observed by brine shrimp lethality b...
