Antibiotic resistance in bacteria is a current threat causing an increasing number of infections difficult clinical management. While the overuse and misuse antibiotics are investigated to reduce them, need for alternatives approaches rising. Carbon-based materials shown recent moderate high antibacterial properties diamond, thanks its superior mechanical, tribological, electrical, chemical bio...
Background & Objective: Azole nucleuses are very important part of antimicrobial, analgesic and anti-inflammatory drugs. The azole class of compounds is the most popular among the antibacterial and antifungal classes because of its lower toxicity, higher efficacy and a broad spectrum of activity. Today, Efforts have focused on the development of new, less toxic and more efficacious antifungal a...
This study demonstrated that the bacteria could adsorb Fe(3+) and reduce Fe(3+) to Fe(2+). Iron had significant bacteriostatic effects, which were directly proportional to the iron concentration and under the influence of pH and chelator. It presumed that the inhibition of Fe(3+) acts through the formation of hydroxyl free radicals.
BACKGROUND The present study investigated the antibacterial activity and underlying mechanisms of ginkgolic acid (GA) C15:1 monomer using green fluorescent protein (GFP)-labeled bacteria strains. RESULTS GA presented significant antibacterial activity against Gram-positive bacteria but generally did not affect the growth of Gram-negative bacteria. The studies of the antibacterial mechanism in...
Peptidoglycan recognition proteins kill bacteria by activating protein-sensing two-component systems
Multicellular eukaryotes have several mechanisms to kill bacteria, including oxidative killing by phagocytic cells, complement and antimicrobial peptides present in phagocytic cells, on body surfaces, secretions and tissue fluids. The mechanisms of killing by these antibacterial systems are well established. Eukaryotes also produce antibacterial proteins such as antibacterial lectins1,2 and PGR...
Selective antibacterial peptides containing less than 30 amino acid residues, cationic, with amphipathic properties, have been the subject of several studies due to their active participation and beneficial effects in strengthening the immune system of all living organisms. This manuscript reports the results of a comparison between the group of selective antibacterial peptides and another grou...
The antibacterial activity and mechanism of berberine against Streptococcus agalactiae were investigated in this study by analyzing the growth, morphology and protein of the S. agalactiae cells treated with berberine. The antibacterial susceptibility test result indicated minimum inhibition concentration (MIC) of berberine against Streptococcus agalactiae was 78 μg/mL and the time-kill curves s...
