Transmission of MRSA Linked to Previous Intensive Care Unit Room Occupants
Staying in a room in the intensive care unit previously occupied by a patient with treatment-resistant bacteria may increase the odds of acquiring such bacteria, according to a report in the October 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Two particular microorganisms cause significant illness and death in hospitals: methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE), according to background information in the article. Researchers previously found that 29 percent of patients who acquire these pathogens develop infections or other complications within 18 months. Floors, beds, gowns, faucets and other hospital room fixtures are persistently contaminated with these bacteria, but it is not known whether levels of the bacteria are high enough to infect additional patients or whether currently mandated cleaning practices are effective in reducing bacterial spread. “Although high-risk rooms may exist because of difficult-to-clean design or poor placement of hand hygiene equipment, transmission may be more directly linked to a prior occupant who harbors a resistant organism rather than to a particular room,” the authors write.

Study shows rising incidence of CA-MRSA muscle infections
Researchers in Houston, Texas have found two bacterial muscle infections common in tropical countries becoming more frequent occurrences along with the emergence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), according to a study published in the Oct. 15 issue of Clinical Infectious Diseases, now available online.

Acanthamoeba polyphagam acts as an incubator for MRSA
Scientists in the UK have found that a type of amoeba acts as an incubator for MRSA bacteria. As amoebae are often found in healthcare environments this discovery has implications for the infection control strategies adopted by hospitals.

MRSA infects and replicates in amoebae
The MRSA ‘superbug’ evades many of the measures introduced to combat its spread by infecting a common single-celled organism found almost everywhere in hospital wards, according to new research published in the journal Environmental Microbiology.

Two Million Americans Harbor MRSA Superbug
New research estimates that about 2 million people carry a strain of drug-resistant bacteria in their noses. The research, conducted by the Centers for Disease Control and Prevention (CDC), is the first reliable nationwide estimate of colonization with Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA). It is published in the Jan. 15 issue of The Journal of Infectious Diseases, now available online.

25% Of Hospital MRSA Bacteraemia Occurs In New Arrivals
One in four cases of MRSA blood stream infection in hospital occur in patients who have just arrived from the community. These patients tend to be older and have been in hospital before.

Zyvox® More Effective than Vancomycin in Treating Complicated Soft Tissue Infections
Pfizer's antibiotic ZYVOX® (linezolid injection, tablets, and for oral suspension) is more effective than vancomycin for the treatment of complicated skin and soft tissue infections (cSSTIs) caused by methicillin-resistant Staphylococcus aureus (MRSA), according to the largest MRSA cSSTIs study to date published in Antimicrobial Agents and Chemotherapy.

Drug-Resistant MRSA a Growing Threat
Infectious diseases researchers at Vanderbilt University Medical Center are noticing a significant increase in the number of infections due to Methicillin-Resistant Staphylococcus Aureus (MRSA) and the number of asymptomatic individuals who harbor the organism in their bodies.

Return of the Staphylococcus aureus "superbug"
Staphylococcus aureus causes a wide variety of diseases including boils and furuncles and more serious diseases such as septicemia and pneumonia, and a debate has long raged about the existence of S. aureus "superbugs" – more dangerous strains that may be associated with particularly invasive disease.
In the December 15 issue of the Journal of Clinical Investigation, Damian Melles and colleagues from University Medical Center Rotterdam examined 829 S. aureus strains from healthy donors from the city of Rotterdam. The genetic relatedness of the strains was compared and revealed the existence of 3 major and 2 minor genetic clusters. These clusters corresponded to the predominant genetic groups identified in a similar analysis recently performed in the United Kingdom, indicating that the same clonal lineages of the organism appear to be dominant in 2 distinct geographic locations.
