Medicinal plants have played a vital role in drug production. Using plant extracts directly has proved to be risk-free. In the current studies, Crude extracts of Caralluma fimbriata stem were used to investigate its antibacterial activity along with their phytochemical screening .Antibacterial assay was carried out by agar disc diffusion technique. Zones of inhibition around the bacterial colon...

objective: nigella sativa (n. sativa) seeds were used in traditional medicine for the treatment of a variety of diseases. the seed extracts and oil of this plant have shown various pharmacological properties including antimicrobial actions. in this study, the in vitro and in vivo antibacterial effects of methanol extract of the seeds against pathogenic bacteria causing mastitis in cows have bee...

conclusions the results of our study showed that plant extracts have good antibacterial properties against pseudomonas aeruginosa and escherichia coli. objectives this research aims to discover the function of some medicine plants on pestiferous pseudomonas aeruginosa and escherichia coli in humans. materials and methods bacterial strains were obtained from a standard laboratory. the strains of...

UNLABELLED Antimicrobial peptides offer potential as novel therapeutics to combat food spoilage and poisoning caused by pathogenic and nonpathogenic bacteria. Our previous studies identified the peptide human beta-defensin 3 (HBD3) as a potent antimicrobial agent against a wide range of beer-spoiling bacteria. Thus, HBD3 is an excellent candidate for development as an additive to prevent food a...

Multidrug-resistant pathogens have become a major public health concern. There is a great need for the development of novel antibiotics with alternative mechanisms of action for the treatment of life-threatening bacterial infections. Antimicrobial peptides, a major class of antibacterial agents, share amphiphilicity and cationic structural properties with cell-penetrating peptides (CPPs). Herei...

Granulocyte chemotactic protein 2 (GCP-2)/CXCL6 is a CXC chemokine expressed by macrophages and epithelial and mesenchymal cells during inflammation. Through binding and activation of its receptors (CXCR1 and CXCR2), it exerts neutrophil-activating and angiogenic activities. Here we show that GCP-2/CXCL6 itself is antibacterial. Antibacterial activity against gram-positive and gram-negative pat...

Alcaligenes faecalisNBIB-017, a Gram-negative bacterium, was isolated from soil in China. Here, we provide the complete genome sequence of this bacterium, which possesses a high number of genes encoding antibacterial factors, including proteins and small molecular peptides.

In continuation of Nepalese medicinal plant screening research, we have examined the antibacterial property of 40 methanol crude extracts in vitro using disc diffusion method against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. Overall, 95 % of the extracts showed antibacterial activity against at least one Gram-negative bacteria and 90 % of the extract...

With increased prevalence of antibioticresistant bacterial, finding new sources with antibacterial activity could be an effective help in diseases. The antibacterial activity and Minimal Inhibitory Concentration (MIC) of the extracts of Calendula Officinalis L., Achillea millefolium L. Millefolium L., Allium haemanthoides Boiss. & Reut. ex Regel, Allium ampeloprasum L. and Echinophora platyloba...

OBJECTIVE To examine the in vitro antibacterial activity of the ethanol extract of fresh fruits of Solanum incanum L., fresh leaves of Ricinus communis L. and Allium ampeloprasum var. porrum L., and to determine and quantify the phenol compounds of the investigated plant parts. METHODS This study was carried out at the Faculty of Science, King Khalid University, Abha, Kingdom of Saudi Arabia ...
