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.

Bacterial toxin closes gate on immune response

Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes.

NSW patients at greater risk of infection by super bugs

A study published late last year on the prevalence of the bug, methicillin-resistant Staphylococcus aureus, or MRSA which showed that far more MRSA bugs were collected in NSW-ACT hospitals than in other states, has been supported by one of Sydney's most senior surgeons.

Weakness found in anthrax bacterium

MIT and New York University researchers have identified a weakness in the defenses of the anthrax bacterium that could be exploited to produce new antibiotics.

No high quality studies on reducing MRSA infection in nursing homes for elderly people

Nursing homes for older people provide environments where bacteria such as meticillin-resistant Staphylococcus aureus (MRSA) are likely to thrive.

Most dangerous form of staph infection comes from single strain

Researchers have discovered that the most dangerous form of staph infection now occurring in the United States originates from a single strain of bacteria, not multiple strains as previously believed.

Studies highlight MRSA evolution and resilience

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain USA300 of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists.

Kiss but don't shake hands to stay healthy!

Scientists from the London School of Hygiene say a quick "air kiss" on the cheek is a relatively-germ free affair when compared to a hand-shake.

New multi-drug resistant microbe bad news for gay men

Sexually active gay men are many times more likely than others to acquire a new, highly antibiotic-resistant strain of the so-called MRSA bacteria widely know as the "superbug," a UCSF-led study shows.

MRSA spike among gay men: More effective prevention needed for MRSA, HIV and other STDs

AIDS Healthcare Foundation (AHF), today expressed concern over a recent study first reported publicly today in an 'Annals of Internal Medicine' article which found that sexually active gay men in San Francisco were 13 times as likely to contract methicillin-resistant Staphylococcus aureus (MRSA), a drug-resistant strain of bacteria, than their heterosexual counterparts.

New superbug puts gay men at risk

New research from the U.S. has found that a potentially deadly bacteria, a type of drug-resistant staph infection, is being transferred between gay men by way of sexual activity.

Research could turn the tables on superbugs

Scientists in Australia and America believe they have found a way to deal with the increasing antibiotic resistance of deadly superbugs such as MRSA.

Australian researchers tackle antibiotic resistance

The development of antibiotic resistant strains of bacteria that are problematic and expensive to treat is a major healthcare problem around the world. The "selective pressure" of antibiotic usage inevitably results in the emergence and proliferation of resistant bacteria.

U.S. healthcare facilities aren't doing enough to protect patients from MRSA

U.S. healthcare facilities aren't doing enough to protect patients from Methicillin-resistant Staphylococcus aureus (MRSA) infections, according to a new poll of infection control professionals released today.

Hospitals cut down on Christmas decorations to curb superbugs

In an attempt to curb the spread of superbugs such as Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile, this Christmas some hospitals in Britain will have fewer Christmas decorations.

Benzethonium chloride products identified as best for killing MRSA

One type of over-the-counter product for topical wound care is more effective than others in killing methicillin-resistant Staphylococcus aureus bacteria, or MRSA, which is potentially deadly and in recent years has moved from its historic hospital setting to a much broader public concern.

New anti-infective drug aims to fight drug-resistant bacteria at source

Deadly methicillin-resistant Staphylococcus aureus - MRSA - a bacterium that responds poorly to conventional antibiotic treatment, infects 90,000 Americans per year and causes 19,000 deaths, most in hospital settings.
