OBJECTIVES Mellitine, a major component of bee venom (BV, Apis mellifera), is more active against gram positive than gram negative bacteria. Moreover, BV has been reported to have multiple effects, including antibacterial, antivirus, and anti-inflammation effects, in various types of cells. In addition, wasp venom has been reported to have antibacterial properties. The aim of this study was to ...

Escherichia coli O157:H7 and Staphylococcus aureus are two of the major pathogens frequently involved in foodborne outbreaks. Control of these pathogens in foods is essential to food safety. It is of great interest in the use of natural antimicrobial compounds present in edible plants to control foodborne pathogens as consumers prefer more natural "green" foods. Allyl isothiocyanate (AITC) is a...

The antibacterial effect of Emblica officinalis essential oil was investigated against Staphylococcus aureus. The solvents used for extraction of essential oil were methanol, dichloromethane, hexane and chloroform. In vitro antibacterial activity was performed by agar well diffusion method. The results obtained in the present study suggest that Emblica officinalis essential oil used the treatme...

The objective of this study was to evaluate the effect of dietary supplementation of antibacterial peptide and zinc methionine on performance and some serum biochemical parameters of weaned piglets. Rongchang male piglets (28 days of age, initial weight 8.4 ± 0.65 kg) were used. All piglets were randomly allotted to four diets including the control group, the antibacterial peptide (AP) group co...

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...

Vancomycin and cholestyramine have been utilized both alone and in combination for the treatment of antibiotic-associated pseudomembranous colitis. Previous work for the treatment of antibiotic-associated pseudomembranous colitis. Previous work has demonstrated significant binding of vancomycin by the anion-exchange resin. The antibacterial activity of vancomycin was markedly reduced when the s...

The aim of this study was to investigate antibacterial effects of oregano and thyme essential oils (EOs) on some food-borne bacteria. GC-MS analysis of EOs was performed in order to determine their composition and phenols were predominant constituents. The investigation of the antibacterial effects of EOs was performed on Salmonella Enteritidis, Salmonella Thyphimurium, Staphylococcus aureus, m...

Antibacterial activity of A. sativum was tested against gram-positive and gram-negative bacterial isolates from Urinary Tract of Indian patients, which were confirmed for resistant against commonly used antibiotics for urinary tract infections. In present study, only five quantities (10, 20, 30, 40 and 50μg) of aqueous allicin from A. sativum cloves and leaves were used, which has antibacterial...

The aim of present work is to study the antibacterial activity of polyphenols isolated from the ethyl acetate soluble of methanol extract of stem bark of Garcinia indica against Staphylococcus aureus, Salmonella typhi and Escherichia coli by paper disc method. The results showed good antibacterial activity against S. aureus at higher concentrations, moderate at lower concentrations, against S. ...

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 ...
