Being naturally derived from the cellular glucose metabolism, glucosamine is present in the hyaluronic acid present in the synovial fluid and also the fluids that help in lubrication of the cartilage in the joint cavities. This monomer, derived from the shell-fish waste or shell-fish chitosan by hydrolysis, it is widely accepted as a dietary supplement by FDA with its increasing commercial pote...

background bacterium-bacterium antagonistic interactions could be important in the ecology of marine bacteria. antimicrobial properties of microorganisms are exploited in various fields of human activities. objectives antagonism of heterotrophic bacteria from different marine environments of tropical and temperate zones was examined. materials and methods bacteria were isolated from biofilm sam...

In this experiment, biosynthesized silver nanoparticles (AgNPs) were synthesized using aqueous leaf extract of Erythrina suberosa (Roxb.). The biosynthesis of silver nanoparticle was continuously followed by UV-vis spectrophotometric analysis. The response of the phytoconstituents resides in E. suberusa during synthesis of stable AgNPs were analyzed by ATR- fourier-transform infrared spectrosco...

There is a need for non-antibiotic, antimicrobial compositions with low toxicity capable of broad-spectrum eradication of pathogenic biofilms in food preparation and healthcare settings. In this study we demonstrated complete biofilm eradication within 60 min with synergistic combinations of caprylic and polygalacturonic (PG) acids in an in vitro biofilm eradication model against representative...

Adhathoda vasica is a well-known herb used in Ayurvedic system of medicine which possesses diverse pharmacological properties. In the present study leaves of Adhathoda vasica were extracted using four different solvents of increasing polarities (chloroform, methanol, ethanol and water). The efficacy of these extracts was tested against various bacterial strains through agar well-diffusion metho...

Leptospira Vanaporn Wuthiekanun (LVW) agar was used to develop a disk diffusion assay for Leptospira spp. Ten pathogenic Leptospira isolates were tested, all of which were susceptible to 17 antimicrobial agents (amoxicillin/clavulanic acid, amoxicillin, azithromycin, cefoxitin, ceftazidime, ceftriaxone, chloramphenicol, ciprofloxacin, clindamycin, doripenem, doxycycline, gentamicin, linezolid, ...

Sida acuta is a shrub indigenous to pantropical regions. The plant is widely used for its various pharmacological properties. Among compounds of pharmacological interest occurring in the plant, are indoloquinoline alkaloids. The aim of the present study was to investigate the antimicrobial activity of alkaloids of S. acuta from Burkina Faso. The alkaloids had a good antimicrobial activity again...

BACKGROUND The formation of biofilms is crucial in the pathogenesis of many acute and subacute microbial infections, including chronic wounds and foreign-body-related infections. Topical antimicrobial therapy with chemical antiseptics or physical treatment with tissue-tolerable plasma (TTP) may be promising to control bacterial infection. METHODS We assessed the efficacy of 0.1% chlorhexidine...

Flow cytometry is a rapid method to quantitate live and dead bacteria in a sample.1-4 It can be used to measure the efficacy of antimicrobial compounds by exposing organisms to the disinfectant and subsequently staining with permeant and impermeant DNA dyes. Test organism viability, measured using a 30-minute flow cytometry assay, showed comparable sensitivity with a standard 48-hour plate coun...

This study aimed to analyze the chemical composition and antioxidant antimicrobial activities of Laurus nobilis L. essential oil (LEO) its fractions obtained by short-path molecular distillation. According composition, it can be said that LEO proved have activity sinceboth a high content total phenolic (TPC). Short-path distillation was used separate with superiorantioxidant activity. Laurel re...
