The aim of this study was to evaluate the effect of EDTA, lysozyme, or the combination of EDTA and lysozyme on the antibacterial activity of ovotransferrin against Escherichia coli O157:H7. Ovotransferrin solutions (20 mg/mL) containing 100 mM NaHCO3 (OS) with added EDTA (2.0 or 2.5 mg/mL), lysozyme (1.0, 1.5, or 2.0 mg/mL), or both were prepared. The antibacterial activities of OS, OSE (OS+EDT...

It is generally accepted that the composition of the medium exerts an important influence on the action of antibacterial substances on microorgani. Many workers have succeeded in paralyzing the effect of antibacterials by the addition to the media of substances such as organ extracts, peptone, and bacterial extracts. Thus, Mcllwain (1941) counteracted the antibacterial effect of acriflavin on E...

The mixture of olive oil and lime cream has been traditionally used to treat external burns in the region of Hatay/Antakya and middle Anatolia. Olive oil and lime cream have been employed by many physicians to treat many ailments in the past. A limited number of studies have shown the antibacterial effect of olive oil and that it does not have any toxic effect on the skin. But we did not find a...

A novel furanone derivative and a polyacid constructed from it were synthesized, characterized and formulated into experimental high strength cements. The compressive strength (CS) and Streptococcus mutans viability were used to evaluate the mechanical strength and antibacterial activity of the cements. The effect of human saliva and aging were investigated. The antibacterial activity against L...

OBJECTIVES We are often confused on selecting a suitable wound dressing for the treatment of infected wounds from huge number of available wound dressings. Then, to help clinicians easily select a wound dressing, we compared the antibacterial effects and bacterial retentivity (ie, potency of keeping absorbed bacteria inside wound dressings and preventing them from leaking out) of wound dressing...

A novel antibacterial glass-ionomer cement has been developed. Compressive strength (CS) and S. mutans viability were used to evaluate the mechanical strength and antibacterial activity of the formed cement. Compressive yield strength (YS), modulus (M), diametral tensile strength (DTS) and flexural strength (FS) were also determined. All the formulated antibacterial cements showed a significant...

Silver nanoparticles are increasingly recognized for their utility in biological applications, especially antibacterial effects. Herein, we confirmed the antibacterial effect of silver nanoparticles on Escherichia coli using the conventional optical density (OD) and colony-forming units (CFU) method and used flow cytometry (FC), TEM and BrdU ELISA to investigate the mechanisms of this effect. F...

The antibacterial activity of the ethanolic and methanolic extracts from the mossEntodon nepalensis Mizush. was evaluated against three bacterial species. The antibacterial activity was assessed by well diffusion method. The ethanolic extract of plant showed a stronger effect than the methanolic extract. The maximum antagonistic effect showed against tested Escherichia coli followed by Salmonel...

Homogeneously distributed zinc nanoparticles (NPs) on the glass substrate were investigated for the transmittance, mechanical durability, and antibacterial effect. The buffered Ti NPs between Zn NPs and glass substrate were studied for an enhancement of the transmittance and mechanical endurance. The Ti NPs buffered Zn NPs showed a high transmittance of approximately 91.5% (at a wavelength of 5...
