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 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.

Novel target for therapeutics against Staphylococcus aureus

Researchers at the Texas A&M Health Science Center Institute of Biosciences and Technology, and the University of Edinburgh have uncovered how a bacterial pathogen interacts with the blood coagulation protein fibrinogen to cause methicillin-resistant Staphylococcus aureus (MRSA) infections, a finding that could aid in developing therapeutics against the potentially deadly disease.

FDA issues complete response letter for Ceftobiprole for treatment of complicated skin infections

Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD), today announced that it received a Complete Response letter from the U.S. Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for ceftobiprole for the treatment of complicated skin and skin structure infections, including diabetic foot infections.

New approach to stopping germs

Keeping germs from cooperating can delay the evolution of drug resistance more effectively than killing germs one by one with traditional drugs such as antibiotics, according to new research from The University of Arizona in Tucson.

U.S. 'super bugs' invading several Colombian cities

Two clones of highly antibiotic-resistant organism strains, which previously had only been identified in the United States, are now causing serious sickness and death in several Colombian cities including the capital Bogota, say researchers at The University of Texas Medical School at Houston.

Superbugs on the rise in Canadian hospitals

Although infection control has been substantially ramped up in Canadian hospitals since the SARS crisis of 2003, the number of resistant bacterial infections post-SARS have multiplied even faster, a new Queen's University study shows.

Researchers downplay value of mandatory universal nasal screening of patients for MRSA

Three Virginia Commonwealth University epidemiologists are downplaying the value of mandatory universal nasal screening of patients for MRSA, arguing that proven, hospital-wide infection control practices can prevent more of the potentially fatal infections.

Ultra-sensitive nanoprobes help tackle MRSA

This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at University College London are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as methicillin-resistant Staphylococcus aureus (MRSA).

Disinfectants can make bacteria resistant to treatment

Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the October issue of the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially making it resistant to being killed by some antibiotics.
