ABSTRACTWe here report on thein vitroactivity of toremifene to inhibit biofilm formation of different fungal and bacterial pathogens, includingCandida albicans,Candida glabrata,Candida dubliniensis,Candida krusei,Pseudomonas aeruginosa,Staphylococcus aureus, andStaphylococcus epidermidis. We validated thein vivoefficacy of orally administered toremifene againstC. albicans and S. aureusbiofilm formation in a rat subcutaneous catheter model. Combined, our results demonstrate the potential of toremifene as a broad-spectrum oral antibiofilm compound.

 Objectives: Hydrocotyle sibthorpiodes is known to contain several phytoconstituents which are constantly involved in the formation of Silver nanoparticles that may affect several multi-drug resistant microbes. Therefore, the study was undertaken to evaluate the efficacy of different concentration of nano silver solution on three bacterial isolates. It was also aimed to qualitatively assess the different phytoconstituents responsible for the synthesis. Methods: Three bacterial isolates of Klebsiella pneumonia, Pseudomonas aeroginosa and Staphylococcus aureus were identified. Synthesis of AgNPs with different concentration (2/4/6/8/10μl/ml) was done and applied to the selected isolates. The phytochemical compounds of the ethyl acetate extract were assayed by several colored reactions qualitatively. Results: The size and stability biosynthesis of the metallic silver nanoparticles were confirmed by photophysical characterization as well as SEM (Scanning Electron Microscopy), XRD (XRay Diffraction), Zeta potential and DLS (Dynamic Light Scattering) with an average size of 13.37 ±10 nm. The increasing concentration of the particle solution showed significant inhibition zone for all the three isolates viz., Klebsiella pneumonia, Pseudomonas aeroginosa and Staphylococcus. aureus showing the value of 3.0±0.17, 2.7±0.32 and 3.6±0.57 respectively for 10 μl/ml concentration. Phytochemical screening of the whole plant extract also revealed an array of bioactive compounds which may have an effective role in the reduction process. Conclusion: The study demonstrated a simple, efficient and eco-friendly synthesis of stable silver nanoparticles from the ethyl acetate extract of Hydrocotyle sibthorpiodes having fairly superior antimicrobial activity against human pathogens.

Abstract Methicillin-resistant Staphylococcus aureus is the cause of nosocomial and community-acquired infections. This study aimed to evaluate the effect of zinc oxide and silver nanoparticles (ZnO-Ag NPs) on biofilms formation and icaA gene expression in methicillin-resistant S. aureus (MRSA). In this study, three standard strains (ATCC 43300, 25923, and 29913) and a clinical isolate are included. The minimum inhibitory concentration (MIC) of nanoparticles was determined by microdilution broth method. The antibacterial effects of ZnO-Ag NPs either alone or in combination with each other were compared with vancomycin (as the control group). The effect of MIC and sub-MIC concentrations of ZnO-Ag NPs on biofilm formation was determined by the microtiter plate method. The expression level of the icaA gene was assessed by real-time PCR LightCycler® 96 software (Version 1.1.0.1320, Roche, Germany). technique. All experiments were repeated three times. Data were analyzed using SPSS software through ANOVA and t-test. The P-value of less than .05 was considered as statistically significant. The average MICs of ZnO, Ag, and ZnO-Ag NPs compounds were 393.2, 179.8, and 60.8 μg/ml, respectively. The compound of ZnO-Ag NPs had a synergistic effect against all isolates. ZnO-Ag NPs decreased the biofilm formation rate at MIC and sub-MIC concentrations (P < .001). Sub-MIC ZnO-Ag NPs concentration significantly reduced the icaA gene expression in S. aureus strains (P < .03). The sub-MIC concentration of ZnO-Ag NPs reduced biofilm formation rate and icaA gene expression in Staphylococcus aureus strains compared with vancomycin. It can be used to cover medical devices after examining more clinical isolates to prevent bacterial colonization.
