a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

Bacterial infection of biomaterials is a major concern in medicine, and different kinds of antimicrobial biomaterial have been developed to deal with this problem. To test the antimicrobial performance of these biomaterials, the airborne bacterial assay is used, which involves the formation of biohazardous bacterial aerosols. We here describe a new experimental set-up which allows safe handling...

introduction: zhumeria majdae is an herbal plant which is only found in hormozgan province. the aim of this study was to compare the antimicrobial property and toxicity of essential oil (eo) and encapsulated form of the essential oil (efeo) of zhumeria majdae. materials and methods: first, the plant was dried, grinded, and its eo extracted by hydrodistallation. then, the eo was encapsulated by ...

conclusions shiitake essential oil is an effective anti-bacterial and anti-biofilm agent on important oral pathogens and has a possible therapeutic potential as an oral anti-biofilm agent. results no inhibitory effect was observed on f. nucleatum biofilms (p > 0.05). significant disruptive properties on a. actinomycetemcomitans at values lower than the mic (3.90 µg/ml) was detected (p < 0.05). ...

Background: Bacteremia due to Enterococcus faecalis is usually caused by strains resistant to most antibiotics. Effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. The aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococc...

In this study the extracellular proteins from isolate LC3 belonging to Aspergillus were purified for new antimicrobial polypeptide (AMP) discovery and then tested activity against Staphylococcus aureus (ATCC 25923) Methicillin-resistant S. (MRSA). Antimicrobial was determined by trypsin/proteinase K assay, which polypeptide-based, it observed that protein a of about 11 kDa gel overlay assay. Th...

New sulfonamide and amide derivatives containing coumarin moieties; oxo-2H-chromen-sulfamoylphenylacetamides and oxo-2H-chromen-arylacetamides were synthesized starting from diverse 2-chloroacetamide derivatives and a wide range of coumarins. The structures of the obtained compounds were elucidated by IR and NMR spectra and also analytical elemental analysis. In the next step, the above mention...

An antimicrobial validatory screening of short nosed tripod fish Triacanthus biaculeatus (Bloch, 1786) collected from the Visakhapatnam coastal waters, India is done in such a way T. biaculeatus muscle extracts were subjected for antimicrobial assay. Antimicrobial screening assay was done in five bacterial pathogens viz., Escherichia coli (MTCC-443), Salmonella typhi (MTCC-421), Pseudomonas aer...

Methicillin-resistant Staphylococcus aureus (MRSA) infection is a serious clinical problem worldwide. The aim of the present study was to examine the antimicrobial activity of oxyresveratrol (ORV) against MRSA. The antimicrobial activity of ORV was evaluated against three strains of MRSA and one methicillin-susceptible S. aureus (MSSA) strain using a minimal inhibitory concentration (MIC) assay...
