Impact of test protocols and material binding on the efficacy of antimicrobial wipes

ConclusionsThe use of different wiping cloth materials may not impact severely on the efficacy of potent disinfectants, despite the absorption of different volumes of formulation by the materials. QAC-based formulations may be at higher risk when a low concentration is used. There were large differences in efficacy depending on the standard test performed, highlighting the need for more stringency in choosing the test to make a product claim on label.

Here, we demonstrate a novel technique to induce the antibacterial response in biomaterial substrates via surface polarization. In the present work, hydroxyapatite, HA-xZnO (x = 3.0, 4.5 and 7.5 wt. %) composites were processed by solid state sintering route at 1250 °C for 2 h. After phase evolution analyses, the detailed dielectric and electrical measurements were perf...

The surface morphology and chemical composition of the obtained multilayers were characterized by atomic force microscopy (AFM), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The plate ...

Molecules doi: 10.3390/molecules24224104 Authors: Katarzyna Zawadzka Marta Nowak Ireneusz Piwoński Katarzyna Lisowska Staphylococcus aureus infections are common and difficult to treat. The increasing number of drug-resistant staphylococcal infections has created the need to develop new strategies for the treatment of these infections. The synergistic antimicrobial activity of different pharmaceuticals seems to be an interesting alternative. The aim of this st...

The high potency of PBL relative to CW blue light makes it a suitable antimicrobial for suppressing bacterial growth in biofilms as wel...

AbstractPurpose of ReviewStaphylococcus aureus is the primary pathogen responsible for osteomyelitis, which remains a major healthcare burden. To understand its dominance, here we review the unique pathogenic mechanisms utilized byS. aureus that enable it to cause incurable osteomyelitis.Recent FindingsUsing an arsenal of toxins and virulence proteins,S. aureus kills and usurps immune cells during infection, to produce non-neutralizing pathogenic antibodies that thwart adaptive immunity.S. aureus also has specific mechanisms for distinct biofilm formation on implants, necrotic bone tissue, bone marrow, and within the osteo...
