Evaluation of Antimicrobial Effects of Photo-sonodynamic Antimicrobial Chemotherapy Based on Nano-micelle Curcumin on Virulence Gene Expression Patterns in Acinetobacter baumannii.

Background: Abaumannii baumannii rapidly resistant to a wide range of antimicrobial agents. The combination of Antimicrobial Photodynamic Therapy (aPDT) and Sonodynamic Antimicrobial Chemotherapy (SACT), known as Photo-Sonodynamic Antimicrobial Chemotherapy (PSACT), has received considerable attention as one of the emerging and promising strategies against microbial infections.

Objective: This study aimed to investigate the antimicrobial effects of PSACT based on nano-micelle curcumin (N-MCur) on the virulence gene expression patterns in A.

Antibiofilm activity of natural zeolite supported NanoZnO: inhibition of Esp gene expression of Enterococcus faecalis.

Aim: To evaluate the antibiofilm effect and esp gene downregulation of Enterococcus faecalis through nanozinc oxide fabricated on natural zeolite (NanoZnO/Ze). Materials & methods:Zeolite and NanoZnO/Ze materials were characterized by x-ray diffraction, x-ray fluorescence and field emission scanning electron microscopy coupled with energy dispersive x-ray. Atomic absorption spectroscopy was used to evaluate zinc release.
