the antibacterial activity of a series of ionic liquids containing short-chained 1-alkyl-3-methylimidazolium cations ([cnmim+]; n = 2, 4, 6 and 8) and bis (trifluoromethylsulfonyl) imide anion ([tf2n]) against e. coli and b. subtilis was measured, for the first time. all ils used in this work were synthesized and analyzed by fourier transform infrared (ft-ir) spectroscopy, nmr, and karl-fischer...

ABSTRACT: This study examines the antibacterial effects of Arum conophalloides on S. typhimurium bacteria at different temperatures (–18°, 8°, 16°, 24°, and 32°C) and time intervals (1, 2, 3, 6, 12, 24, and 48 days). This local plant was studied to determine the greatest effect caused by the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) as well as the a...

In the emerging issue of increased multi-resistant properties in foodborne pathogens, silver nano particles are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Nano Colloidal Silver towards food-borne pathogens such as Escherichia coli O157:H7, Listeria monocytogenes, Salmonella enterica Serovar Ty...

Four strains of Burkholderia pseudomallei were used to determine the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and time-kill curves with 13 single antimicrobial agents: ceftazidime, piperacillin, imipenem, amoxicillin/clavulanic acid, doxycycline, cotrimoxazole, kanamycin, rifampicin, ciprofloxacin, trovafloxacin, clarithromycin, azithromycin and meropenem...

OBJECTIVES This study was aimed to find out the minimum inhibitory concentration (MIC) of five essential oils against oral pathogens and to find out the minimum bactericidal concentration (MBC) and minimum fungicidal concentration (MFC) of five essential oils against oral pathogens. MATERIALS AND METHODS The antimicrobial activities by detecting MIC and MBC/MFC of five essential oils such as ...

Bactericidal testing historically has exhibited variable reproducibility, even when prior standardized methods were employed. Several modifications to the National Committee for Clinical Laboratory Standards (NCCLS) broth macrodilution method are proposed to improve reproducibility. Recommended changes from the approved NCCLS guidelines (M21-A and M26-A) include omitting serum supplementation o...

this study has been done to survey of solvent system effect on extraction of grape seed extract and its antimicrobial properties. for this purpose, grape seed extracts were extracted with six different solvent systems. minimum bactericidal concentration (mbc) of extract on six spoilage and food-born pathogens was determined. the results indicated that mbc of different extracts have no significa...

In this study, based on our previous derivatives of naphtho[2,3-b]furan-4,9-diones were synthesized and their antimicrobial activities evaluated. The screening these naphthoquinones revealed that the fluorine-containing NQ008 compound exhibited potent broad against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), Gram-negative bacteria, fungi. results ratio m...

This study sought to give a scientific basis to plants already used for traditional purposes and also probe new antibacterial constituents from randomly selected plants whose anti-infective properties have not been evaluated. The antibacterial activity of ethanolic extracts from 19 Zimbabwean plants was assessed using the agar diffusion assay, minimum inhibitory concentration and minimum bacter...

According to biologically active compounds and traditional use of the Satureja bachtiarica, seem that this plant has significant antimicrobial effects. In this study antimicrobial effect of extracts evaluated by two methods, “Collins method” and “disk agar diffusion method” on Escherichia coli PTCC 1330 and Staphylococcus aureus PTCC 1337 microorganisms. The minimum inhibitory concentration (MI...
