Staphylococcus aureus News and Research

RSS

Staphylococcus aureus is a spherical bacterium (coccus) which on microscopic examination appears in pairs, short chains, or bunched, grape-like clusters. These organisms are Gram-positive. Some strains are capable of producing a highly heat-stable protein toxin that causes illness in humans.

Study may lead to personalized treatments for cystic fibrosis

Some 2,103 mutations have been identified in patients with cystic fibrosis (CF), the most common fatal genetic disease in Canada, and together they pose huge challenges for patients and researchers, including those affiliated with Université de Montreal and its teaching hospital, the Centre hospitalier de l'Université de Montréal (CHUM).

Adults carrying MRSA bacteria are twice as likely to die within the next decade

A University of Florida study of middle-aged and older adults finds those who unknowingly carry methicillin-resistant Staphylococcus aureus, or MRSA, on their skin are twice as likely to die within the next decade as people who do not have the bacteria.

New study uncovers potential therapeutic target for lupus

A recent study published in JCI found that a neutrophil's endoplasmic reticulum, the organelle that normally makes proteins in the cell, becomes stressed in the autoimmune disorder lupus.

Repurposed heart and flu drugs that protect platelets improve survival of septic mice

Despite continued improvements in antibiotics and hospital intensive care, staph sepsis -; a bloodstream infection caused by Staphylococcus aureus bacteria -; still causes severe illness or death in 20 to 30 percent of patients who contract it.

Standardized drying protocol for goldenseal could lead to more predictable health outcomes

Developing a standardized drying protocol for goldenseal could lead to more predictable health applications and outcomes by preserving the alkaloids found in the plant, which is native to Appalachia, according to Penn State researchers, who conducted a new study of the medicinal forest herb.

Highly sensitive DNA nanosensor can accurately detect lethal superbugs

The persistent overuse of antibiotics has led to the evolution of antibiotic resistant pathogens, or “superbugs,” which can cause severe life-threatening infections that must be diagnosed and treated early on.

University of Strathclyde signs licensing deal for its patented HINS-light technology

The new Environment Care Lighting technology range created by Linea Light Group using High Intensity Narrow Spectrum (HINS) light developed and patented by the University of Strathclyde in Glasgow, will enable the Woofer and Rollip appliances from the i-LèD Professional collection to decontaminate surfaces and prevent infection, destroying up to 70-80% of bacteria with continuous use.

Synthesis of photocatalytic and antibacterial materials for removing medicines from wastewater

The Theoretical and Computational Chemistry Laboratory (QTC) of the Jaume I University of Castellón (UJI), in collaboration with the Centre for the Development of Functional Materials (CDMF) of the Universidad Federal de São Carlos (UFSCar), has published an article entitled “Selective Synthesis of α-, β-, and γ-Ag2WO4 Polymorphs: Promising Platforms for Photocatalytic and Antibacterial Materials” in scientific journal Inorganic Chemistry, which showcases new photocatalytic and antibacterial materials to remove medicines from wastewater.

Scientists optimize wastewater disinfection process to minimize spread of antibiotic resistance

Antibiotic-resistant bacteria have become a global threat today, owing in part to the efficiency with which resistance spreads among them. Some of this spread happens in waterbodies—and our wastewater systems are no exception.

Multidrug-resistant S. aureus strains may be spreading between pigs, farmworkers in North Carolina

DNA sequencing of bacteria found in pigs and humans in rural eastern North Carolina, an area with concentrated industrial-scale pig-farming, suggests that multidrug-resistant Staphylococcus aureus strains are spreading between pigs, farmworkers, their families and community residents, and represents an emerging public health threat, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health.

Study profiles the nose to predict immune response during COVID-19

SARS-CoV-2 resides in mucous membranes, making it easy to detect viral load in the nasal cavities. An international group of researchers has characterized the immunological and diagnosis characteristics of patients who may have or are confirmed with SARS-CoV-2 infection. The team found a distinct nasal cytokine profile that could help identify patients at risk for high inflammatory responses to SARS-CoV-2 infection.

Self-sterilizing polymers are effective at inactivating SARS-CoV-2 virus

Researchers from North Carolina State University, Boston University, and Kraton Corporation have demonstrated a family of self-sterilizing polymers that are effective at inactivating coronaviruses, including SARS-CoV-2 - the virus that causes COVID-19.

Researchers develop new weapon to fight against resistant bacteria

Every day, people die from simple infections even though they have been treated with antibiotics. This is because more and more bacteria have become resistant to the types of antibiotics that doctors can prescribe.

Research highlights public health burden posed by livestock-associated MRSA

For Michigan State University's Felicia Wu, the surprise isn't that people who work with livestock are at higher risk of picking up antibiotic-resistant bacteria, but instead how much higher their risk levels are.

Iron-carrying extracellular vesicles promote viral-bacterial co-infection

The mechanism by which acute viral respiratory infections promote secondary bacterial growth and infection in the airways depends on iron-carrying extracellular sacs secreted by the cells lining the host's airways, report researchers from the University of Pittsburgh School of Medicine in a paper published today in Cell Reports.
