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 outbreak tracked and contained using DNA sequencing

Scientists have used DNA sequencing for the first time to effectively track the spread of, and ultimately contain, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA), according to new research published in The Lancet Infectious Diseases.

DNA sequencing helps detect MRSA outbreaks in hospitals

This study used DNA sequencing to examine an outbreak of MRSA in a hospital, to uncover new cases and, as the study developed, to intervene in the outbreak to end it more quickly. Sequencing illuminated each person infected and described the transmission of MRSA between people coming to the hospital and within the hospital.

Certain UTI-causing bacteria become more difficult to treat with current antibiotics

Certain types of bacteria responsible for causing urinary tract infections (UTIs), the second-most-common infection in the United States, are becoming more difficult to treat with current antibiotics, according to new research from Extending the Cure (ETC), a project of the Center for Disease Dynamics, Economics & Policy.

Study: Superbug MRSA prevalent at wastewater treatment plants in the U.S.

A team led by researchers at the University of Maryland School of Public Health has found that the "superbug" methicillin-resistant Staphylococcus aureus (MRSA) is prevalent at several U.S. wastewater treatment plants (WWTPs).

Universal approach to MRSA-prevention in ICU is most effective

Universal decolonization of all patients admitted to intensive care units using chlorhexidine baths and mupirocin treatment for 5 days significantly reduces the risk for infection with methicillin-resistant Staphylococcus aureus , report researchers.

Simple approach results in low rates of MRSA infections

High compliance with hand hygiene and focusing on other simple infection control measures on medical, surgical and neuroscience intensive care units resulted in reduced rates of methicillin-resistant Staphylococcus aureus (MRSA) infection by 95 percent in a nine-year study, according to research findings by Virginia Commonwealth University physicians presented during IDWeek 2012.

Researchers increase potency of a compound that reactivates antibiotics against MRSA

Researchers from North Carolina State University have increased the potency of a compound that reactivates antibiotics against methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant form of Staphylococcus that is notoriously difficult to treat. Their improved compound removes the bacteria's antibiotic resistance and allows the antibiotic to once again become effective at normal dosage levels.

People living near livestock may be at increased risk of LA-MRSA

People who live near livestock or in livestock farming communities may be at greater risk of acquiring, Methicillin-resistant Staphylococcus Aureus (MRSA), according to a new study led by an international team of researchers from the Johns Hopkins Bloomberg School of Public Health, the Dutch Institute for Public Health and the Environment (RIVM) and VU University Medical Center in Amsterdam.

Positive results from Cempra's IV solithromycin Phase 1 study

Cempra, Inc., a clinical-stage pharmaceutical company focused on developing antibiotics to meet critical medical needs in the treatment of bacterial infectious diseases, today announced results of its Phase 1 study of intravenous (IV) solithromycin in healthy subjects. The study demonstrated that IV solithromycin was well tolerated, showed a favorable pharmacokinetic profile (PK) and achieved relevant plasma concentrations.

Report finds increase in occurrence of MRSA bacteria in Denmark

In 2011, more Danes became infected with MRSA bacteria, and the number was the highest in over 25 years. The increase was primarily seen in otherwise healthy people without any hospital relation. Although the number of MRSA positive pig herds is on a par with the level seen in 2010, significantly more pigs at slaughter were found to be infected with the so-called pig MRSA, and the number of people infected with pig MRSA is increasing. This appears from the Danish surveillance report, DANMAP, for 2011.

Small fragments of keratin protein in the eye play a key role in warding off pathogens

When it comes to germ-busting power, the eyes have it, according to a discovery by University of California, Berkeley, researchers that could lead to new, inexpensive antimicrobial drugs.

Ciprofloxacin use is major contributor to MRSA spread in hospitals

The use of a commonly prescribed antibiotic is a major contributor to the spread of infection in hospitals by the 'superbug' MRSA, according to new research. The study also found that increasing measures to prevent infection - such as improved hygiene and hand washing - appeared to have only a small effect on reducing MRSA infection rates during the period studied.

New tools can help track healthcare-associated infections in nursing homes

The Society for Healthcare Epidemiology of America (SHEA) and Centers for Disease Control and Prevention (CDC) have each released new tools and information to help track deadly healthcare-associated infections (HAIs) in nursing homes and other long-term care settings.

Orthopedists should suspect necrotizing fasciitis in patients with out of proportion pain

Dr. Russell Russo, an Orthopedic Surgeon at LSU Health Sciences Center New Orleans, and other researchers stress that orthopedists should have a high index of suspicion for necrotizing fasciitis, or flesh-eating bacterial infection, in every patient with pain or other symptoms that are out of proportion to the initial diagnosis. Their recommendations are published in the September 2012 issue of Orthopedics Today.
