Host-bacteria metabolic crosstalk drives S. aureus biofilm [PDF]

Microbial Cell, 2021
Staphylococcus aureus is a prominent pathogen that can cause intractable lung infections in humans. S. aureus persists in the airway despite inflammation and immune cell recruitment by adapting to host-derived antimicrobial factors.

Polarization-Sensitive Surface-Enhanced In Situ Photoluminescence Spectroscopy of S. aureus Bacteria on Gold Nanospikes. [PDF]

Sensors (Basel), 2020
We report the possibility of a time-resolved bacterial live/dead dynamics observation with the use of plasmonic nanospikes. Sharp nanospikes, fabricated on a 500-nm thick gold film by laser ablation with the use of 1030-nm femtosecond pulses, were tested as potential elements for antibacterial surfaces and plasmonic luminescence sensors. Staphylococcus

Anti-S. aureus and anti-List. monocytogenes molecules produced by cheese-isolated lactic acid bacteria [PDF]

Czech Journal of Food Sciences, 2014
Nine lactic acid bacteria from artisanal-made cheeses were investigated for their ability to inhibit Listeria monocytogenes and Staphylococcus aureus. Both extracellular and surface-bound bacteriocins were recovered. While Lb. plantarum molecule was present only extracellularly, all the other strains displayed interference in both compartments. Maximum

ZrO₂ Ceramic without and with Fullerene C₆₀ Films: In Vitro Direct-Contact Model Using <i>E. coli</i> and <i>S. aureus</i> Bacteria. [PDF]

J Funct Biomater
Zirconia is known as a strong and bioinert load-bearing material for dental implants. It typically exhibits no antibacterial activity. Inflammation is a crucial problem for dental implant surgery: about 3–5% of all dental implants experience inflammation.

MIL-53 MOF on Sustainable Biomaterial for Antimicrobial Evaluation Against <i>E. coli</i> and <i>S. aureus</i> Bacteria by Efficient Release of Penicillin G. [PDF]

J Funct Biomater
The development of efficient antibiotic-releasing materials derived from sustainable and recyclable compounds represents a key area within biomedical materials science, particularly in the treatment of antibacterial infections. Herein, a Fe3+/terephthalate-based metal–organic framework (MIL-53) and a novel advanced material made of MIL-53 with biogenic

Competition between skin antimicrobial peptides and commensal bacteria in type 2 inflammation enables survival of S. aureus

Cell Reports, 2023
During inflammation, the skin deploys antimicrobial peptides (AMPs) yet during allergic inflammation it becomes more susceptible to Staphylococcus aureus. To understand this contradiction, single-cell sequencing of Il4ra-/- mice combined with skin microbiome analysis reveals that lower production of AMPs from interleukin-4 receptor α (IL-4Rα ...

Recent Advances in Multi-Drug Resistance (MDR) Efflux Pump Inhibitors of Gram-Positive Bacteria S. aureus [PDF]

Antibiotics, 2013
The paper focuses on recent achievements in the search for new chemical compounds able to inhibit multidrug resistance (MDR) mechanisms in Gram-positive pathogens. An analysis of the results of the search for new efflux pump inhibitors (EPIs) for Gram-positive bacteria, which have been performed over the last decade, indicates that almost all efforts ...

Assessing the prevalence and antibiotic susceptibility patterns of S. aureus bacteria isolated from Iraqi women with vaginosis

Iraqi Journal of Science, 2022
     Bacterial vaginosis (BV) is a common infection that occurs when the number of lactobacillus spp. bacteria (vaginal flora) decreases in the vaginal canal. The study aimed to determine the prevalence of Staphylococcus aureus within vaginosis in order to emphasize the importance of early detection and treatment.

Comparative stability and growth requirements of S. aureus and faecal indicator bacteria in seawater

Water Science and Technology, 2006
The fate (stability, multiplication) of S. aureus, E. coli and E. faecalis was determined in three classes of recreational waters (seawater, estuarine, stream) supplemented with nutrients in the form of sewage and peptone. In the absence of sunlight (24±2 °C), all bacteria in all water samples did not multiply and were slowly (days) inactivated.
