the presence of antibacterial activity in bovine β-lactoglobulin and in α-lactalbumin hydrolysates was investigated. the plasmin-digest of β-lactoglobulin (pdβ) and of α-lactalbumin (pdα) were fractionated, using reversed phase high performance liquid chromatography. the antibacterial activity of β-lactoglobulin, α-lactalbumin, nisin, plasmin, pdβ and pdα were in vitro tested against pathogenic...

In the present investigation, aqueous, ethanol and petroleum ether, ethanol (1:1) root extracts of Seidenfia rheedii were tested against 12 different human pathogenic bacteria for antibacterial activity. It was found that ethanolic extracts inhibited the growth of all the bacterial strains tested whereas moderate antibacterial activity was associated with petroleum ether, ethanol (1:1) root ext...

A glycine-mediated mixed-solvothermal approach has been proposed for the synthesis of novel Cu(2)O structures with different morphologies and the morphology effect on the antibacterial activity of the obtained Cu(2)O crystals has been studied, confirming that the obtained Cu(2)O crystals all show good antibacterial effects and that with the morphology of the Cu(2)O crystals changing from cubic ...

background and objective: nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. medicinal plants are also of great importance as antibacterial agents. therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of net...

Treatment of clinical isolates of human pathogenic bacteria, which were known to be resistant to multiple commonly-used antibiotics, with refined leukocyte extracts from the American alligator (Alligator mississippiensis) resulted in a timeand concentration-dependent inhibition of bacterial proliferation. The alligator leukocyte extract exhibited the strongest antibacterial effect on Pseudomona...

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 ...

This article reviews the present state of the art in the field of flexible antibacterial coatings which efficiently kill bacteria on their surfaces. Coatings are formed using a reactive magnetron sputtering. The effect of the elemental composition and structure of the coating on its antibacterial and mechanical properties is explained. The properties of Cr-Cu-O, Al-Cu-N, and Zr-Cu-N antibacteri...

The purpose of the present study was to determine the antibacterial activity of oolong tea extract on oral streptococci, including Streptococcus mutans and Streptococcus sobrinus, and to identify the response to its components. Antibacterial activity was found when the extract was added to S. mutans cells in chemically defined medium but not in complex broth media. Further, pretreatment with bo...

Background and objective: Six families of thiazole, thiazolidine, imidazole, tetrahydropyrimidine, oxazolidine and thiazepine are new and important heterocyclic antibacterial compounds. Aim of this study is evalution the antibacterial effect of thirty new thiazole, thiazolidine, imidazole, tetrahydropyrimidine, oxazolidine and thiazepine derivatives against Bacillus subtilis and salmonella ente...

objective(s): the present study was designed to investigate the antibacterial function and pharmacological effect of elephant garlic (allium ampeloprasum var. ampeloprasum) on u2os human osteosarcoma cells.   materials and methods: seven kinds of bacteria were reconstituted, inoculated and tested in this research to evaluate elephant garlic antibacterial activity. by the means of facs analysis,...
