In vitro anti- biofilm and anti-bacterial activity of Sesbania grandiflora extract against Staphylococcus aureus
The main objective of this research is to investigate the anti-biofilm and anti-bacterial activity of Sesbania grandiflora (S. grandiflora) against Staphylococcus aureus. S. grandiflora extract were prepared and analyzed with UV -Vis spectroscopy, Fourier transform infrared spectroscopy, Dynamic light scattering. Biofilm forming pathogens were identified by congo-red assay. Quantification of Ex...
متن کاملAnti-biofilm Activity of Selected Plant Essential Oils against Pseudomonas aeruginosa and Staphylococcus aureus
Antibiotic resistance is a crucial grievous menace to public health on a planetary scale as it plummet the effectiveness of treatment and increase morbidity and mortality (Cassandra et al., 2008). Highly resistant bacterial evolution resulted in the compromised use of new generation of antibiotics (Levy, 2002). Antibiotic resistance is due to an inherent ability of microorganism to form surface...
متن کاملCutaneous injury induces the release of cathelicidin anti-microbial peptides active against group A Streptococcus.
Cathelicidins are a family of peptides thought to provide an innate defensive barrier against a variety of potential microbial pathogens. The human and mouse cathelicidins (LL-37 and CRAMP, respectively) are expressed at select epithelial interfaces where they have been proposed to kill a number of gram-negative and gram-positive bacteria. To determine if these peptides play a part in the prote...
متن کاملPropolis: anti-Staphylococcus aureus activity and synergism with antimicrobial drugs.
Propolis is a natural resinous substance collected by bees from tree exudates and secretions. Its antimicrobial activity has been investigated and inhibitory action on Staphylococcus aureus growth was evaluated. The in vitro synergism between ethanolic extract of propolis (EEP) and antimicrobial drugs by two susceptibility tests (Kirby and Bauer and E-Test) on 25 S. aureus strains was evaluated...
متن کاملActivity of maltodextrin and vancomycin against staphylococcus aureus biofilm.
We aimed to assess the anti-biofilm activity of vancomycin, maltodextrin, and their combination against vancomycin resistant Staphylococcus aureus (VRSA) and vancomycin-susceptible S. aureus (VSSA) strains based on an in vitro static model. Biofilms of 4 VSSA and 2 VRSA strains were grown in a 96-well static model. Vancomycin 2 mM, maltodextrin 10 mM, and both in combination were tested using t...
