Polyphenols from four medicinal plants of Burkina Faso, Combretum micranthum, Khaya senegalensis, Pterocarpus erinaceus and Sida acuta, were screened for their antioxidant and antimicrobial activities against pathogenic bacteria. The medicinal plants displayed different polyphenols contents and antioxidant activities. The bark of P. erinaceus had the highest antioxidant activity. Some microorga...

conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...

Resistance to antimicrobial agents is an emerging problem worldwide. Awareness of the undesirable consequences of its widespread occurrence has led to the initiation of antimicrobial agent resistance monitoring programs in several countries. In 1995, Denmark was the first country to establish a systematic and continuous monitoring program of antimicrobial drug consumption and antimicrobial agen...

herbs have been used for its medicinal properties from several thousand years ago. herbs, essences and extracts, possess a variety level of biological activities and antimicrobial activities of a large number of them have been proved. eucalyptus is one of these plants which the anti-virus effects of its extract has long been used to treat influenza and colds in most parts of the world. the aim ...

in this study, antimicrobial activity of chitosan and whey protein isolate edible films incorporated with different concentrations of zataria multiflora boiss essential oil ;zeo (1%, 2%, 3% and 4% v/v) and zataria multiflora boiss essential oil nanoliposome (0, 1, 2, 3 and 4%) against  listeria monocytogenes (atcc 19118), bacillus cereus (atcc 11778), staphylococcus aureus (atcc 65138), escheri...

Emergence of new infectious diseases such as tuberculosis, bacterial and fungal diseases have stimulated public interest and inspired commitments by medicinal chemists to control these diseases. Increasing microbial resistance has become a very serious clinical problem for many classes of antibiotics. Therefore, it is an urgent requirement to design and synthesize novel antimicrobial agents to ...

Natural Antimicrobial peptides (AMPs) are important components of immune systems and possess immuno-modulatory and broad spectrum antimicrobial activities. These host-defense peptides failed to resist protease degradation or to efficiently inhibit biofilm formation. We describe in this review the different strategies to improve AMPs and develop peptides that could be used clinically and in indu...

Ethanolic extract of Naringi crenulata or liminonia crenulata leaves was investigated for Phytochemical and Antimicrobial activities. The macroscopic characteristics of leaves, physical constant values, extractive values, behavior on treatment with different chemical reagents of the powdered leaves. Naringi crenulata were studied to fix some pharmacognostical parameters and preliminary phytoche...

Background The Psidium guajava, commonly known as the apple guava, has shown various biological activities related to its main constituents, such as flavonoids, carotenoids, terpenoids and phenolic compounds. Studies emphasize antispasmodic and antimicrobial properties in the treatment of diarrhea and dysentery. It also has hypoglycemiant, antioxidant, hepatoprotective, anti-allergic, antimicro...

Cationic host defence (antimicrobial) peptides are an important component of the innate immune systems of a wide variety of plants, animals, and bacteria. Although most of these compounds have direct antimicrobial activities under specific conditions, a greater appreciation for the diversity of functions of these molecules is beginning to develop in the field. In addition to their directly anti...
