An Antimicrobial Metabolite from Bacillus sp.: Significant Activity Against Pathogenic Bacteria Including Multidrug-Resistant Clinical Strains
In this study, the cell free modified tryptone soya broth (pH 7.4 ± 0.2) of Bacillus subtilis URID 12.1 showed significant antimicrobial activity against multidrug-resistant strains of Staphylococcus aureus, S. epidermidis, Streptococcus pyogenes and Enterococcus faecalis. The partially purified antimicrobial molecule was found to be resistant to extremes of pH and temperatures and also to high...
متن کاملSynergistic Antimicrobial Activity of Camellia sinensis and Juglans regia against Multidrug-Resistant Bacteria
Synergistic combinations of antimicrobial agents with different mechanisms of action have been introduced as more successful strategies to combat infections involving multidrug resistant (MDR) bacteria. In this study, we investigated synergistic antimicrobial activity of Camellia sinensis and Juglans regia which are commonly used plants with different antimicrobial agents. Antimicrobial suscept...
متن کاملActivity of topical antimicrobial agents against multidrug-resistant bacteria recovered from burn patients.
BACKGROUND Topical antimicrobials are employed for prophylaxis and treatment of burn wound infections despite no established susceptibility breakpoints, which are becoming vital in an era of multidrug-resistant (MDR) bacteria. We compared two methods of determining topical antimicrobial susceptibilities. METHODS Isolates of Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (...
متن کاملAedesin: Structure and Antimicrobial Activity against Multidrug Resistant Bacterial Strains
Multidrug resistance, which is acquired by both Gram-positive and Gram-negative bacteria, causes infections that are associated with significant morbidity and mortality in many clinical settings around the world. Because of the rapidly increasing incidence of pathogens that have become resistant to all or nearly all available antibiotics, there is a need for a new generation of antimicrobials w...
متن کاملAntimicrobial activity of bioactive compound(s) produced by Bacillus species
Antibiotics are metabolic by-products of complex biosynthetic pathways in microorganisms. They are usually produced by aerobic spore-forming bacteria in the genera Bacillus and Streptomyces and in the Fungi Penicillium and Cephalosporium. Antimicrobials such as bacteriocins are inhibitory peptides or proteins, which have bactericidal effects on micro-organisms closely related to the producer. T...
