New antibiotic shows promise for treating MRSA pneumonia
A drug approved just two years ago for treating bacterial infections may hold promise for treating the potentially fatal MRSA pneumonia, according to a Henry Ford Hospital study. Researchers found that patients treated with the antibiotic ceftaroline fosamil, or CPT-F, had a lower mortality rate after 28 days than the mortality rate seen in patients treated with vancomycin, the most common drug therapy for MRSA pneumonia.

Trial shows using two drugs not better than one when treating MRSA blood infections
Researchers attempting to improve the treatment for methicillin-resistant Staphylococcus aureus (MRSA) blood infections have discovered the combination of two antibiotics was no better than one, and led to more adverse effects. In what is the biggest trial of MRSA bloodstream infections to date, (352 participants from Australia, Singapore, New Zealand and Israel), the CAMERA2 clinical trial, researchers were surprised to see the drug combination wasn't as effective as anticipated. (2020-02-11)

Manuka honey may kill bacteria by destroying key bacterial proteins. Dr. Rowena Jenkins and colleagues from the University of Wales Institute -- Cardiff investigated the mechanisms of manuka honey action and found that its antibacterial properties were not due solely to the sugars present in the honey. The work was presented this week at the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh. (2009-09-06)

Study could help battle against superbugs
Targeting a toxin released by virtually all strains of MRSA could help scientists develop new drugs that can fight the superbug, research suggests. A study led by the University of Edinburgh has discovered the toxin -- SElX -- which leads the body's immune system to go into overdrive and damage healthy cells. (2011-10-13)

Community-acquired MRSA spreads
Drug resistant hospital superbugs like MRSA have been kept under control in Denmark for more than 30 years. But the latest reports say that in the last 10 years MRSA cases have risen 10 times as new strains of bacteria with resistance genes spread through the community, scientists heard Tuesday, April 1, 2008, at the Society for General Microbiology's 162nd meeting being held this week at the Edinburgh International Conference Center.

(2013-10-26)

New MRSA variant detected in cow's milk that can evade some existing detection methods
An article published online first by the Lancet Infectious Diseases reports detection of a new variant of meticilin-resistant Staphylococcus aureus in cow's milk -- genetically different to existing MRSA strains -- from the UK and Denmark. This new variant is associated with clinical disease in people, yet some existing testing methods would wrongly identify this new variant as meticillin-susceptible, leading to prescriptions of the wrong antibiotics. (2011-06-02)

Risk of transmission of livestock-associated MRSA to non-farm dwellers is negligible
At a swine farm with pigs carrying methicillin-resistant Staphylococcus aureus, levels of MRSA among 95 percent of visitors became virtually undetectable only two hours after exposure. MRSA in the nasal passages was associated with exposure to airborne MRSA and not directly on physical contact with the animals. The research is published Sept. 29 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. (2017-09-29)

Cigarette smoke makes superbugs more aggressive
Methicillin-resistant Staphylococcus aureus, 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. The study, published March 30 by Infection and Immunity, shows that MRSA bacteria exposed to cigarette smoke become even more resistant to killing by the immune system. (2015-04-02)

Study: Optimal treatment duration for MRSA-related pneumonia
The national practice guideline for treating MRSA-related pneumonia is seven to 21 days. A Henry Ford Hospital study found that effective treatment can be done in half the time. Researchers found that 40 percent of patients were treated for eight to 13 days on a therapy of the antibiotics vancomycin or linezolid, and had the highest survival rate. (2012-10-19)

Antibiotics and biocidal cleaners may spread multidrug resistance in MRSA
Antibiotic use on people or pets, and use of biocidal cleaning products such as bleach, are associated with multidrug resistance in methicillin-resistant Staphylococcus aureus (MRSA) in the home. This contamination of the home environment may contribute to reinfection of both humans and animals with MRSA, and to subsequent failure of treatment. The research is published Sept. 22 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. (2017-09-22)

MRSA: Political point-scoring over hospital cleanliness ignores the real issue
Political point-scoring over policies to control MRSA (meticillin-resistant Staphlococcus aureus) confuses cleanliness with the real failure in UK hospitals - poor hand hygiene and inadequate use of gloves, states an editorial in this week's issue of THE LANCET. (2005-03-31)

Being an MRSA carrier increases risk of infection and death
Patients harboring methicillin-resistant Staphylococcus aureus for long periods of time continue to be at increased risk of MRSA infection and death, according to a new study in the July 15 issue of Clinical Infectious Diseases, currently available online. (2008-07-02)

A MRSA infection with a reduced susceptibility to the potent antibiotic drug vancomycin is linked to high mortality, according to a Henry Ford Hospital study. Researchers found that patients who contracted a MRSA infection with heteroresistance, called hVISA, stayed in the hospital longer, were more likely to have the infection return after 90 days, and were twice as likely to die from it after 90 days than patients who do not have hVISA. (2010-09-12)

Ring fencing of hospital wards and simple infection control measures can eradicate MRSA in patients having planned operations and allow more patients to be treated, show researchers in this week's BMJ. (2004-07-15)

Genome sequencing traces MRSA spread in high transmission setting
Methicillin-resistant Staphylococcus aureus is a common cause of hospital-acquired infections, with the largest burden of infections occurring in under-resourced hospitals. While genome sequencing has previously been applied in well-resourced clinical settings to track the spread of MRSA, transmission dynamics in settings with limited infection control is unknown. In a study published online today in Genome Research, researchers used genome sequencing to understand the spread of MRSA in a resource-limited hospital with high transmission rates. (2014-12-09)
