nowadays, uncontrolled and frequent use of antibiotics may cause emergence of microbial resistanceamong pathogenic agents. therefore, the use of new synthetic and natural antimicrobial compounds isinevitable. one source of natural compounds in this respect comes from plants. the purpose of this study was to examine the antibacterial effects of peel extracts from sour and sweet pomegranate. meth...

The in vitro susceptibility of group D streptococci (enterococci) to ampicillin was studied comparing the results obtained in Mueller-Hinton broth (MHB) with those obtained in normal human serum (NHS). The rate of enterococcal killing was consistently faster in NHS than in MHB at equivalent ampicillin concentrations. Whereas an increasing media pH appeared to decrease the susceptibility of ente...

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...

licorice (glycyrrhiza glabra l.) is an important medicinal plant. in this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. bacillus subtilis, enterococcus faecalis, klebsiella pneumoniae, pseudomonas aeruginosa, staphylococcus aureus and escherichia coli, and candida albicans were used as test organisms...

Dried leaves of Acalypha indica was extracted with methanol by cold percolation. From the observed data, crude extraction concentration 500 and 250 μg completely arrest the bacterial growth except Enterococcus faecalis and Shigella boydii. 125 μg concentration crude extract also completely inhibit the bacterial cell growth in Escherichia coli, Pseudomonas aeruginosa, and P. mirabilis and Staphy...

In the present study, antibacterial activity of aqueous and organic extracts of Psidium guajava leaves was evaluated against multidrug resistant (MDR) clinical isolates of Staphylococcus aureus strains collected from hospitals in northern (Malabar region) Kerala. The strains which exhibited resistance against all the antibiotics tested was selected for antibacterial assays. Minimum inhibitory c...

BACKGROUND The ability of bacteria to develop common mechanisms of resistance to antibiotics and disinfectants raises doubts about the effectiveness of disinfection processes. Glucoprotamin (GP) is an antimicrobial active substance which is widely used to the disinfection in medical area. OBJECTIVE The aim of study was to compare GP's effectiveness with susceptibility of reference strains use...

Introduction:  Nowadays  the  medical,  therapeutic  and  pharmacological  application  of  magnetic  fields  (MF)  and  its  biological  effect  has  raised  question  about  the  safety  of  MF.  This  study  aimed  at  scrutinizing the effect of static MF on the resistance of S. aureus to antibiotic.  Materials and Methods: This prospective, case–control study was conducted to evaluate the e...

The current investigation aims to test the susceptibility of human pathogenic clinical isolates and MTCC strains leaf seed extracts Terminalia catappa Nigella sativa. Disc diffusion assay, micro dilution assay minimum Bactericidal Concentration investigated bacteria extracts. active extract was subjected phytochemical screening, separation phytochemicals by Thin Layer Chromatography, bioactivit...
