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.

MRSA study suggests strategy shift needed to develop effective therapeutics

USA300-the major epidemic strain of methicillin-resistant Staphylococcus aureus (MRSA) causing severe infections in the United States during the past decade-inherits its destructiveness directly from a forefather strain of the bacterium called USA500 rather than randomly acquiring harmful genes from other MRSA strains.

Supermarkets should offer free flu shots rather than free antibiotics

As influenza season shifts into high gear, with 24 states now reporting widespread activity, the nation's infectious diseases experts are urging supermarket pharmacies with free-antibiotics promotions to educate their customers on when antibiotics are the right prescription-and when they can do more harm than good.

Johns Hopkins safety team works to eliminate bloodstream infections in the nation and the world

A widely heralded Johns Hopkins safety initiative to reduce bloodstream infections in intensive care units (ICUs) was implemented in 30 states starting Feb. 1 and could save an estimated $3 billion dollars and 30,000 lives annually.

MRSA infections in ICU patients have been decreasing in recent years

In contrast to the perception that methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections associated with use of a catheter is an increasing problem in intensive care unit (ICU) patients, the incidence of this type of infection decreased by nearly 50 percent from 1997 - 2007, according to a study in the February 18 issue of JAMA.

MRSA head and neck infections increase among children

Rates of antibiotic-resistant head and neck infections increased in pediatric patients nationwide between 2001 and 2006, according to a report in the January issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.

MRSA's weak point visualised by scientists

An enzyme that lives in Methicillin-resistant Staphylococcus aureus (MRSA) and helps the dangerous bacterium to grow and spread infection through the human body has been visualised for the first time, according to a study out today in Proceedings of the National Academy of Sciences (PNAS).

Discovery of new way for bacteria to transfer toxic genes to unrelated bacterial species

In a laboratory experiment, the scientists from NYU School of Medicine discovered that Staphylococcus aureus, a notorious bacterium that causes toxic shock syndrome and many other types of infections and is the scourge of hospitals nationwide due to its growing antibiotic resistance, could co-opt viral parasites as secret pipelines for transferring toxin genes to vastly different bacterial species.

MRSA pre-screening effective in reducing otolaryngic surgical infection rates

Pre-operative screening of patients for methicillin-resistant Staphylococcus aureus (MRSA) may be an effective way to reduce infection rates following otolaryngic surgeries, according to new research published in the January 2009 issue of Otolaryngology - Head and Neck Surgery.

Blocking mechanism found for antibiotic resistance in bacteria

It's as simple as A, T, G, C. Northwestern University scientists have exploited the Watson-Crick base pairing of DNA to provide a defensive tool that could be used to fight the spread of antibiotic resistance in bacteria -- one of the world's most pressing public health problems.

Evolutionary roots of ancient bacteria may open new line of attack on cystic fibrosis

The redox-active pigments responsible for the blue-green stain of the mucus that clogs the lungs of children and adults with cystic fibrosis (CF) are primarily signaling molecules that allow large clusters of the opportunistic infection agent, Pseudomonas aeruginosa, to organize themselves into structured communities.
