Twelve extracts obtained from nine plants belonging to six different genera of Clusiaceae were analyzed against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus and Enterococcus faecalis) bacteria using the microdilution broth assay. Tovomita aff. longifolia, T. brasiliensis, Clusia columnaris, Garcinia madruno, Haploclathra paniculata, and Ca...

The aim of this study was to determine the effects of the essential oil of Thymus serpyllum L. and of its components thymol and total phenols (total phenolic content, TPC) extracted from the plant on the growth and mycotoxin production of Aspergillus ochraceus, A. carbonarius, and A. niger. Minimal inhibitory concentration (MIC) determined for the essential oil and thymol, and selected concentr...

antimicrobial activity of different parts of croccus sativus l. (saffron) including stigma, stamen, leaves and colora, extracted by various solvents, were tested against different bacteria (microccucos luteus, staphylococcus epidermitis, staphylococcus aureus and e. coli) and fungi (candida albicans, aspergillus niger and cladospourium sp) by cup plate diffusion method. minimal inhibitory conce...

A new class of highly functionalized tetrahydroisoquinolines with a quaternary carbon stereocenter was synthesized starting from an easily accessible L-tartaric acid. Nine strains of bacteria (Staphylococcus aureus, Streptococcus pyogenes, Streptococcus mutans, Streptococcus salivarius, Bacillus subtilis, Enterococcus faecalis, Moraxella catarrhalis, Escherichia coli, Campylobacter jejuni) were...

Campylobacter fetus is a rare etiological agent of neonatal meningitis. However, it is a clinically significant bacterium because many cases of neonatal meningitis caused by C. fetus result in death or severe sequelaen. Recently, two new carbapenem antibiotics, meropenem (MEPM) and panipenem (PAPM), which possess relatively good ability to penetrate into the cerebrospinal fluid and a lower risk...

The composition of supercritical CO2 extracts and essential oils obtained by hydrodistillation of Bupleurum fruticosum L., growing spontaneously in Italy and Portugal, and its antifungal activity is reported. The collected extracts were analyzed by GC-FID and GC-MS methods. The minimal inhibitory concentration (MIC) and the minimal lethal concentration (MLC) were used to evaluate the antifungal...

Antimicrobial activity of different parts of Croccus sativus L. (saffron) including stigma, stamen, leaves and colora, extracted by various solvents, were tested against different bacteria (Microccucos luteus, Staphylococcus epidermitis, Staphylococcus aureus and E. coli) and fungi (Candida albicans, Aspergillus niger and Cladospourium sp) by cup plate diffusion method. Minimal Inhibitory Conce...

Serious concerns have been expressed about potential health risks of Nano silver containing consumer products (AgNPs) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of AgNPsinbiomedicalproducts with special concerns to the mutagenic potentials. In this study, we examined the inhibitory and mutagenicity effects of AgNPs in three different ...
