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.

Scientists engineer powerful novel anti-microbial molecules from wasp venom

Now, a team of scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered potent novel anti-microbial molecules from toxic proteins found in wasp venom. The researchers believe that the discovery holds promise in fighting the increasing number of antibiotic-resistant bacteria, that cause serious illness.

Special formulation of inhaled niclosamide may be effective against SARS-CoV-2

Now in new research published on the preprint server bioRxix*, a novel formulation of the drug Niclosamide (NIC) is observed to be effective against SARS-CoV-2 and MERS-CoV in mouse models; it also protects against methicillin-resistance Staphylococcus aureus pneumonia and inflammatory lung damage.

New document discusses how to prevent staphylococcus aureus infections in critically ill infants

Neonatal intensive care units (NICU) should balance prevention of Staphylococcus aureus infections in critically ill infants with the need for skin-to-skin contact with parents and siblings, according to a Society for Healthcare Epidemiology of America (SHEA) white paper published in the journal Infection Control & Hospital Epidemiology.

Allergic immune response against bacteria is not pathological but protective

Allergy is one of the most common diseases in Europe, it is estimated that more than 150 million Europeans suffer from recurring allergies and by 2025 this could have increased to half of the entire European population.

Researchers identify biomarkers associated with bacterial infection mortality

David Gonzalez's "a-ha" moment came when a physician-colleague, George Sakoulas, MD, shared with him one of the biggest problems faced in clinical practice: How long it takes to diagnose a patient.

Lysin-based antibacterial agent can help treat drug-resistant bacterial infections

The Centers for Disease Control and Prevention (CDC) has prioritized finding effective treatment of Methicillin-resistant Staphylococcus aureus (MRSA), one of the most common bacterial pathogens and the single most deadly drug-resistant bacteria in the United States.

Exponential rise in COVID-19 hospitalization risk with age due to waning T cell immunity

The age-related increase in the risk of severe disease and death from COVID-19 mirrors earlier patterns seen with infections. Such trends may help understand the mechanisms underlying the clinical feature. A recent study published in the preprint server medRxiv* in August 2020 shows the effect of age and sex on COVID-19 hospitalization rates in the USA and helps understand how immune function is involved in this pandemic.

Study suggests novel strategy to slow down evolution of antibiotic resistance

The rise of antibiotic resistance in many pathogens has been driven by the spread of a small number of strains, suggesting that some bacteria may be genetically pre-disposed to evolving resistance.

Synthetic peptide can make multidrug-resistant bacteria sensitive to antibiotics

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a synthetic peptide that can make multidrug-resistant bacteria sensitive to antibiotics again when used together with traditional antibiotics, offering hope for the prospect of a combination treatment strategy to tackle certain antibiotic-tolerant infections.

Researchers show usefulness of potential 'phage cocktail' therapy on wound infections

Australian researchers have shown how viruses can be used to save lives, developing the potential use of bacteriophages in bandages to treat life-threatening golden staph infections which may not respond to traditional antibiotics.

Medieval medicine to tackle antibiotic resistance

Biofilm-associated infections are notoriously difficult to treat, and they also play a role in antibiotic resistance as more antimicrobials are urgently needed to treat biofilm-associated infections. These biofilms act as protective layers that prevent the antibiotics from reaching and destroying the targeted bacteria.

Research highlights the potential of AI in identifying pathogens of pneumonia

A team of researchers showed that artificial intelligence (AI) could help predict the type of bacteria that caused the infection in patients with pneumonia.
