OBJECTIVE To examine the in vitro antibacterial activity of the ethanol extract of fresh fruits of Solanum incanum L., fresh leaves of Ricinus communis L. and Allium ampeloprasum var. porrum L., and to determine and quantify the phenol compounds of the investigated plant parts. METHODS This study was carried out at the Faculty of Science, King Khalid University, Abha, Kingdom of Saudi Arabia ...

Silver-based hybrid nanomaterials are gaining interest as potential alternatives for conventional antimicrobial agents. Herein, we present a simple, facile and eco-friendly approach for the deposition of silver nanoparticles (AgNPs) on ZnO nanorods, which act as a nanoreactor for in situ synthesis and as an immobilizing template in the presence of arginine. The presence of arginine enhanced the...

Exposure to the soil-borne pathogens Burkholderia pseudomallei and Burkholderia cenocepacia can lead to severe infections and even mortality. These pathogens exhibit a high resistance to antibiotic treatments. In addition, no licensed vaccine is currently available. A nanoscale platinum-containing titania photocatalyst (TiO(2)-Pt) has been shown to have a superior visible light-responsive photo...

Swift developments in nanotechnology have prominently encouraged innovative discoveries across many fields. Carbon-based nanomaterials have emerged as promising platforms for a broad range of applications due to their unique mechanical, electronic, and biological properties. Carbon nanostructures (CNSs) such as fullerene, carbon nanotubes (CNTs), graphene and diamond-like carbon (DLC) have been...

Bamboo materials with improved antibacterial performance based on ZnO and graphene oxide (GO) were fabricated by vacuum impregnation and hydrothermal strategies. The Zn2+ ions and GO nanosheets were firstly infiltrated into the bamboo structure, followed by dehydration and crystallization upon hydrothermal treatment, leading to the formation of ZnO/GO nanocomposites anchored in the bulk bamboo....

The crude venom of the centipede Scolopendra subspinipes mutilans, injected with Escherichia coli K12D31 for 3-4 days showed broad-spectrum antimicrobial activity against Gram-positive. Gram-negative bacteria and fungi. It showed good antibacterial activity against E. coli K12D31 at different temperatures, pH, and ionic strengths. The crude venom was heated at 100 degrees C for 30 min, centrifu...

The objective of this study was to evaluate the antibacterial activities of joint fluids of patients undergoing total-knee arthroplasty (TKA). Thirty patients who were scheduled for primary cemented TKA were enrolled in the study. The patients were grouped on the basis of whether the cement was without antibiotic loading (control group) or loaded with oxacillin (oxacillin group) or vancomycin (...

The aim of this research was to test the antibacterial activity of Pinus pinaster aqueous bark extract (PABE) and its basic components against multidrug-resistant isolates of Acinetobacter baumannii belonging to European clone I and II, isolated previously from the clinical outbreaks. The minimum bactericidal concentration of PABE against both clones of A. baumannii was 200 mg ml–1, while lower...

To prevent and treat diseases caused by the spread of microbes, humans have invented all sorts of effective antimicrobial substances. The most widely used antimicrobial substance is antibiotics. However, misuse of antibiotics can generate various negative effects, bacterial resistance, decreased immunity, and internal flora imbalance which can lead to endogenous infection. In addition, existing...

This study was carried out to synthesize 1D inorganic nanostructure using an electrochemical method without any template and additives. Copper foils were anodized in a KOH bath and were tested for their antibacterial performance. After anodizing, the obtained samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) to determine the corresponding morphology an...
