In this study, the antimicrobial activity of the acetone, diethyl ether and ethanol extracts of the lichen Cetraria aculeata has been investigated. The extracts were tested against twelve bacteria and eight fungi and found active against Escherichia coli, Staphylococcus aureus, Aeromonas hydrophila, Proteus vulgaris, Streptococcus faecalis, Bacillus cereus, Bacillus subtilis, Pseudomonas aerugi...

Since the traditional methods of treatment have proven ineffective against chronic wounds involving biofilms, the present study evaluates the in vitro efficacy of a novel wound gel comprising an antibiofilm DispersinB ® enzyme and a broad-spectrum antimicrobial triclosan against chronic wound-associated bacteria. The antimicrobial and antibiofilm activity of DispersinB ® -triclosan wound gel wa...

abstract         background and objective: lavandula stoechas is a species of native and permanent plants in golestan province that belongs to the family lamiaceae. l. stoechas has been used in traditional medicine for treatment of various diseases. the aim of this study was to extract essential oil using steam distillation method from the flowers of l. stoechas collected from jahan-nama region...

Licorice (Glycyrrhiza glabra L.) is an important medicinal plant. In this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. Bacillus subtilis, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli, and Candida albicans were used as test organisms...

Endophytes are microorganisms that live inside the host plant tissues which have novel metabolites exhibiting a variety of biological activities against different pathogens. This study was carried out to isolate endophytic bacteria and fungi from Terminalia arjuna (marutham), Catharanthus roseus (nithyakalyani) and Azadirachta indica (vembu) and to assess their antimicrobial activity against Ps...

background and objectives: endophytic actinobacteria colonize inside the plant tissues without causing damages to the host plant. since these microorganisms colonize in the different parts of plants and can stop plant disease, they have been applied as biological agents for controlling human diseases. the aim of this study was molecular identification and measuring the antimicrobial activity of...

Different N-substituted benzisoselenazol-3(2H)-ones, analogues of ebselen were designed as new antiviral and antimicrobial agents. We report their synthesis, chemical properties as well as study on biological activity against broad spectrum of pathogenic microorganisms (Staphylococcus aureus, Staphylococcus simulans, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Candida albic...

Innate immunity involving antimicrobial peptides represents an integrated and highly effective system of molecular and cellular mechanisms that protects host against infections. One of the most frequent hospital-acquired pathogens, Staphylococcus aureus, capable of producing proteolytic enzymes, which can degrade the host defence agents and tissue components. Numerous antimicrobial peptides der...
