Staphylococcus aureus News and Research RSS Feed - Staphylococcus aureus News and Research

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.
Bathing patients in common hospital soap can reduce MRSA contamination

Bathing patients in common hospital soap can reduce MRSA contamination

Holding hope for a relatively inexpensive way to improve care and prevent the spread of deadly hospital-acquired infections, a new study reports that bathing patients in a common hospital soap, called chlorhexidine, was equally effective in preventing the transmission of the methicillin-resistant Staphylococcus aureus (MRSA) as the common practice of having healthcare workers avoid physical contact with the patients.

Common tapeworm drug effectively treats MRSA superbugs in lab

Common tapeworm drug effectively treats MRSA superbugs in lab

A new study provides evidence from lab experiments that a drug already used in people to fight tapeworms might also prove effective against strains of the superbug MRSA, which kills thousands of people a year in the United States. [More]
Rising shortages of key antibiotics raise serious concerns about effects on patient care

Rising shortages of key antibiotics raise serious concerns about effects on patient care

Shortages of key antibiotics, including gold-standard therapies and drugs used to treat highly resistant infections, are on the rise, according to a new study of shortages from 2001 to 2013 published in Clinical Infectious Diseases and available online. The trends raise serious concerns about the effects on patient care, particularly for infections without effective alternative treatment options. [More]
New UV light method could help stop spread of hospital superbugs

New UV light method could help stop spread of hospital superbugs

Can a robot clean a hospital room just as well as a person? According to new research out of the Texas A&M Health Science Center College of Medicine, that is indeed the case. Chetan Jinadatha, M.D., M.P.H., assistant professor at the Texas A&M College of Medicine and chief of infectious diseases at the Central Texas Veterans Health Care System in Temple, is studying the effectiveness of a germ-zapping robot to clean hospital rooms, which could hold the key to preventing the spread of "superbugs" - in turn, saving countless dollars and, most importantly, lives.

MRSA bacteria exposed to cigarette smoke become more resistant to antimicrobial peptides

MRSA bacteria exposed to cigarette smoke become more resistant to antimicrobial peptides

Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers at the University of California, San Diego School of Medicine now report that cigarette smoke may make matters worse. [More]

Researchers at Thomas Jefferson University and the National Institutes of Health are building on their research which seeks to understand why joint infections persist despite standards of care designed to stop them. [More]
Two common antibiotic treatments equally effective against MRSA skin infections

Two common antibiotic treatments equally effective against MRSA skin infections

Researchers funded by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, have found that two common antibiotic treatments work equally well against bacterial skin infections caused by methicillin-resistant Staphylococcus aureus (MRSA) acquired outside of hospital settings.

Antibiotic nanoparticles can help treat lung infection, prevent drug resistance

Antibiotic nanoparticles can help treat lung infection, prevent drug resistance

Treating respiratory disease is often difficult because drugs have to cross biological barriers such as respiratory tissue and mucosa, and must therefore be given in large quantities in order for an effective amount to reach the target. [More]
Study shows that households can serve as reservoir for transmitting MRSA

Study shows that households can serve as reservoir for transmitting MRSA

Households can serve as a reservoir for transmitting methicillin-resistant Staphylococcus aureus (MRSA), according to a study published this week in mBio, the online open-access journal of the American Society for Microbiology. Once the bacteria enters a home, it can linger for years, spreading from person to person and evolving genetically to become unique to that household. [More]
