Antibacterial activity of Fe3O4 nanoparticles was investigated in three microorganisms including P. aeruginosa, E. Coli and Staphylococcus aureus. Fe3O4 nanoparticles were synthesized by chemical precipitation method (20 nm). The Fe3O4 nanoparticles antibacterial effect against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were studied by the culture method. First of all, e...

The present study includes antimicrobial activity of Memecylon umbellatum Alcoholic extract showed maximum antibacterial activity Staphylococcus aureus. (gram positive) and it also showed antibacterial activity against gram negative bacteria and also alcoholic extract alone showed slight antifungal activity.

In the past few years, the world has taken a new view to herbal remedies and their applications and many researchers in various fields of medicine are studying this subject. In our program searching for antibacterial agents we have selected an extract prepared from the Pentanema divaricata. No report on the antibacterial activity of this species has been published in literature. Pentanema divar...

background and objectives: the main aims of this study have been finding out the antibacterial activity and preliminary phytochemical screening of some fern species. methods: the antimicrobial activity of the methanol extracts of polypodium interjectum shivas, polystichum woronowii fomin, polystichum aculeatum (l.) roth., dryopteris affinis (lowe) fraser-jenk, athyrium filix-femina (l.) roth, a...

We synthesized peptide-resin conjugates (1 and 2) by immobilizing β-sheet antibacterial peptide and α helical antibacterial peptide on PEG-PS resin, respectively. Conjugate 1 showed considerable antibacterial activity in various conditions, whereas conjugate 2 did not exhibit antibacterial activity. The growths of various bacteria were inhibited by conjugate 1 even at lower concentrations than ...

A peptide (C13) corresponding to the last 13 amino acids of the carboxyl terminus of human platelet factor IV was found to be antibacterial. Amino acid substitutions predicted to disrupt either the amphipathic or alpha-helical nature of C13 rendered the peptide inactive. Antibacterial activity was demonstrated in normal human serum on bacteria which had been previously exposed to low levels of ...

abstract nanoparticles (nps) are increasingly recognized as their usage in biological applications including nanomedicine and food safety. purpose of this study was study on comparison of antibacterial effect of zno nanoparticles in apple juice at 25 and 4 ° c. the present study investigated the antibacterial activity of zno was tested against listeria monocytogenes, escherichia coli, staphyloc...

The study was to investigate the Antibacterial Activity of Some Medicinal Plants used against UTI Causing Pathogens. Bacteria were isolated from the UTI infected patients and characterized by using microscopic, staining, morphological and biochemical methods. The Ethanolic Extracts from plants were prepared and then used to check their antibacterial activity against the bacteria isolated from U...

The alcoholic and aqueous extracts of five medicinal plants (Cassia fistula, Albizia lebbeck, Cassia occidentalis , Sphaeranthus indicus and Vitex nigundo) collected from Uttarakhand, North India; were evaluated for antibacterial activity by Agar diffusion method against medically important bacteria viz. B. subtilis, K. pneumonia, E. coli, Enterobacter aerogenes, Pseudomonas aeruginosa, S. aure...
