Antimicrobial assays are important tools to test and screen the inhibitory effects of myriad compounds against microorganisms before establishing their inhibitory spectra (broad vs. narrow). Knowledge of the inhibitory spectra of antimicrobial compounds before their application in the fields of agriculture, biotechnology, and medicine is crucial. Various conventional and contemporary methods ar...

We examined the frequency of isolation and the antimicrobial resistance of Burkholderia cepacia complex, Stenotrophomonas maltophilia and Achromobacter xylosoxidans in cystic fibrosis patients from 2000 to 2004. Strains susceptibility to tobramycin, piperacillin/tazobactam, imipenem, gentamicin, ciprofloxacin and ceftazidime was determined by disc diffusion assay. B. cepacia complex showed a ve...

In this work the antimicrobial activity of TiO2 nanopore thin films sensitized by Copper tetracarboxyphthalocyanines (TcPcCu) was investigated. TiO2 thin films were deposited by magnetron sputtering and the sensitization process was done by adsorption process. The samples were characterized by scanning electronic microscopy (SEM), Fourier Transform infrared spectroscopy (FTIR), UV-Vis spectroph...

Early targeted antimicrobial therapy helps decrease costs and prevents the spread of antimicrobial resistance, including in Escherichia coli, the most frequent Gram-negative bacterium that causes sepsis. Therefore, rapid susceptibility testing represents the major prerequisite for knowledge-based successful antimicrobial treatment. To accelerate testing for antibiotic susceptibility, we have de...

the antimicrobial efficacy of methanol and water extracts of seeds of the plant swietenia macrophylla (family: meliaceae) was evaluated against selected pathogenic bacterial strains (bacillus cereus mtcc 430, klebsiella penumoniae mtcc 109, pseudomonas aeruginosa mtcc 424, escherichia  coli mtcc 443, staphylococcus aureus mtcc 96, salmonella typhimurium mtcc 98, micrococcus luteus mtcc 106) and...

abstract         background and objective: lactic acid bacteria are gram-positive, catalase-negative, nonsporulating, either rod- or coccus-shaped bacteria that have beneficial effects on their hosts by producing antimicrobial substances such as lactic acid, hydrogen peroxide, bacteriocins and biosurfactants. bacteriocins are antimicrobial peptides that are produced by bacteria and can inhibit ...

BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the chemical composition and antimicrobial activity of Satureja hortensis and Trachyspermum copticum essential oils against different kinds of microorganisms in vitro. MATERIAL AND METHODS The antimicrobial activity was evaluated by micro broth dilution assay and the chemical composition of essential oils was analyzed by GC and G...

Marine bacteria were isolated from seawater was collected from different coastal areas of the Tamilnadu Sea. The antimicrobial activities of these bacteria were investigated. Ethyl acetate extracts of marine bacterial fermentation were screened for antimicrobial activities using the method of agar diffusion. The results showed that 25 strains of the isolates have antimicrobial activity. The pro...
