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.

Nationwide safety program successfully cuts hospital-onset MRSA infections

A large-scale, federally funded quality improvement program developed in collaboration with infection prevention experts at the Johns Hopkins Armstrong Institute for Patient Safety and Quality was associated with a 65% reduction in hospital-onset bloodstream infections caused by methicillin-resistant Staphylococcus aureus (MRSA) among participating hospital units.

Far-UVC light tested to combat avian influenza on farms

When a strain of highly pathogenic avian influenza, HPAI, tore through U.S. poultry farms in early 2025, farmers culled tens of millions of birds and egg prices soared.

POET-II trial reduces antibiotic duration for infective endocarditis by two weeks

A response-tailored strategy reduced antibiotic duration by two weeks without compromising the safety of patients with left-sided infective endocarditis.

Ancient proteins revived to inspire new antimicrobial treatments

University of Oregon biologists have resurrected prehistoric proteins up to 160 million years old that carry natural antimicrobial properties.

AI predicts vaccine response based on pre-existing antibody patterns

Vaccines protect most people from serious illness, but the strength of that protection can vary considerably from one person to another. A new study led by Arizona State University helps us understand why.

Engineered immune cells help eliminate severe bacterial infections effectively

Severe bacterial infections remain a major global health challenge because antibiotics alone often fail when the host immune system becomes dysfunctional.

Natural gut molecule could strengthen chickens' immune response against bacterial infections

A naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections, has been identified by University of Bristol-led research.

Firearm injury patients face measurable risk of bacterial infections

A new study from researchers at the University of Maryland School of Medicine (UMSOM) found that bacterial infections develop in approximately 5 percent of adults hospitalized with firearm injuries, with most infections occurring during the initial hospitalization rather than after patients return home.

Genome-mining tool reveals new antibiotic hidden in a silent gene cluster

Researchers developed DiscERN, a genome-mining platform that combines four complementary algorithms to identify evolutionarily related biosynthetic gene clusters and prioritize candidates for experimental study. The approach revealed discomycin A, a previously unknown calcium-dependent lipopeptide antibiotic with potent activity against several Gram-positive bacteria.

New plant-based wound dressing delivers antibiotics to fight infections

A new dressing made from plant-based materials can deliver antibiotics directly to wounds during critical early stages of infection, according to researchers from the University of Bath.

New bionic skin wound dressing accelerates infected tissue healing

Dressings face a critical limitation: no single product has successfully integrated protective function, wearing comfort, and efficient antibacterial activity.

Botanical prebiotics may steer skin microbes toward healthier balance

Researchers tested plant-derived prebiotic candidates against selected skin-associated bacteria and found that garlic, flaxseed, and mango ginger extracts inhibited S. aureus or acne-associated C. acnes in vitro. Onion and guduchi extracts modestly promoted S. epidermidis, suggesting a microbiome-targeted skincare route that now needs validation in skin models and human studies.

New strategy restores vancomycin effectiveness against resistant bacteria

Antibiotic resistance is one of the most urgent threats to global health, linked to an estimated 4.7 million deaths worldwide in 2019 alone.

AI-guided microneedle patch changes shape to heal chronic wounds

Chronic wounds remain a major healthcare challenge, especially for people with diabetes, who often experience delayed healing, persistent inflammation, and a higher risk of infection.

Bionic cooling skin accelerates healing and combats wound infections

As the global burden of infected wounds continues to rise-with over 300 million surgeries performed annually and postoperative infections affecting 5–20% of patients-conventional wound dressings face a critical limitation: no single product has successfully integrated protective function, wearing comfort, and efficient antibacterial activity.

Australia’s diphtheria outbreak shows why boosters, antibiotics, and better housing all matter

A 131-case diphtheria outbreak in Australia’s Northern Territory showed how toxigenic Corynebacterium diphtheriae can re-emerge even in highly vaccinated populations. Genomic and epidemiological evidence linked most cases to a dominant ST381 strain, with transmission shaped by overcrowding, poor skin health, and persistent health inequities.
