Streptococcus pyogenes plays an important role in the pathogenesis of tonsillitis. The present study was conducted to evaluate the in vitro antibacterial activities of 18 essential oils chemotypes from aromatic medicinal plants against S. pyogenes. Antibacterial activity of essential oils was investigated using disc diffusion method. Minimum Inhibitory Concentration of essential oils showing an...

Germanium (Ge), as an elemental semiconductor material, has been an attractive candidate for manufacturing semiconductor microelectronic device. In the present investigation, to improve the biocompatibility of Ge-based device, graphene film is directly deposited on the Ge surface with different coverage area by controlling the growth time. Compared to bare Ge, the presence of graphene film enti...

The aim of this study was to assess the antibacterial activity of grape vinegar against F. psychrophilum.The antibacterial activity was determined by using agar well diffusion assays. The vinegar was tested against two strains of F.psychrophilum.While the highest inhibition zone diameter of grape vinegar was determined as 60 mm, the lowest was 47mm against to the pathogen. Grape vinegar display...

Interest in antibacterial textiles has been increasing recently. Different kinds of antibacterial textiles with different effectivity are being sold in the market. The influence of time on the antibacterial activity of such textiles is not known generally. The goal of this research was to study the mechanism of commercially available antibacterial agent meant for cotton with regard to the influ...

BACKGROUND Recent public health efforts, including in the UK and US, have targeted decreasing unnecessary antibiotic use. In the US, prescribing for acute non-specific respiratory infections (ARIs) has decreased, but broad-spectrum antibacterial prescribing has soared. AIM To assess recent trends in antibacterial prescribing for ARIs in the UK. DESIGN OF STUDY Retrospective cohort. SETTIN...

This study evaluated the effect of EDTA and lysozyme on the antibacterial activities of activated ovotransferrin against 5 strains of Listeria monocytogenes. First, a disc test was performed to screen the concentrations of EDTA or lysozyme that showed antibacterial activities in ovotransferrin (O) or ovotransferrin in 100 mM NaHCO3 (OS) solution. Turbidity and viability tests were conducted usi...

Staphylococcus aureus is a Gram-positive bacterium that causes many harmful and life-threatening diseases. Some strains of this bacterium are resistant to available antibiotics. This study was designed to evaluate the ability of indigenous actinomycetes to produce antibacterial compounds against S. aureus and characterize the structure of the resultant antibacterial compounds. Therefore, a slig...

in the present study, we reported the essential oils chemical composition and antibacterial activities of the aerial parts of ajuga chamaecistus ging. ex benth. subsp. scoparia (boiss.) rech.f. thatwere collected duringmay 2013 and april 2014 and extracted by sde (simultaneous distillation–extraction) and clevenger apparatus. gc/ms analysis of the plant essential oils led to the identification ...

INTRODUCTION Many essential oils have been advocated for use in complementary medicine for bacterial and fungal infections. However, few of the many claims of therapeutic efficacy have been validated adequately by either in vitro testing or in vivo clinical trials. OBJECTIVE To study the antibacterial activity of nine commercially available essential oils against Streptococcus mutans in vitro...
