background and objectives: the present work was carried out to investigate the ability of spirulina platensis to produce antimicrobial substance against bacteria and fungi. materials and methods: the cells of the cyanobacterium were subjected to different extractions and the purified antagonistic compound proved to be effective against broad spectrum of bacteria and fungi. the antagonistic com...
abstract sesbania grandiflora leaves are extensively used locally since ancient time as in traditional systems. base on mainly folkloric use, we investigated to know the potential of sesbania grandiflora leaves extracts through biological works in vivo and in vitro. the ethanolic extract of s. grandiflora leaves was partitioned into ethyl acetate soluble fraction (esf), petroleum ether soluble ...
nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. antimicrobial nanocomposite ldpe films containing zno nanoparticles at different concentrations (e.g. 1%, 3%, 5% and 3% nano-zno pulse 10% polyethylene grafted maleic anhydride (pe-g-ma), w/w pure ldpe), were p...
The Metagenomics and Metadesign of the Subways and Urban Biomes (MetaSUB) International Consortium is a novel, interdisciplinary initiative comprised of experts across many fields, including genomics, data analysis, engineering, public health, and architecture. The ultimate goal of the MetaSUB Consortium is to improve city utilization and planning through the detection, measurement, and design ...
conclusions the excellent antimicrobial activities of the tested eos might be due to their major phenolic or alcoholic monoterpenes with known antimicrobial activities. hence, these eos can be possibly used as an antimicrobial agent in treatment and control of oral pathogens. results the tested eos inhibited the growth of examined oral pathogens at concentrations of 0.015-16 µl/ml. among the ex...
OIMOMI found that Escherichia coli 443, E. coli 5 and Enterococcus 1294 produced an ether-extractable compound active against Candida1), and applied this ether extract locally for treatment of nasal complications of the common cold and trychophytiasis of the feet.2,3) The results suggested some effect of this crude extract, which was found also to inhibit growth of staphylococci and streptococc...
Background and purpose: Research for discovery and development of new and effective antimicrobial agents has been raised due to increasing rate of numerous multi-drug resistant pathogens. Marine bacteria especially Bacillus species are a rich source of potentially versatile secondary metabolites with antimicrobial activities. In this study, sediments of the Caspian Sea were screened for natural...
Fidaxomicin is bactericidal against Clostridium difficile. The combined results of 8 in vitro studies of 1323 C. difficile isolates showed the minimum inhibitory concentration (MIC) range of fidaxomicin to be ≤ 0.001-1 μg/mL, with a maximum MIC for inhibition of 90% of organisms (MIC(90)) of 0.5 μg/mL. Isolates from 2 phase III clinical trials demonstrated that fidaxomicin MICs of baseline isol...
hyssopus officinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...
