| NIH Scientists Link Quickly Spreading Gene to Asian MRSA Epidemic | National Institutes of Health (NIH) scientists and their colleagues in China have described a rapidly emerging Staphylococcus aureus gene, called sasX, which plays a pivotal role in establishing methicillin-resistant S. aureus (MRSA) epidemics in most of Asia. Senior author Michael Otto, PhD, of NIH's National Institute of Allergy and Infectious Diseases, says these findings illustrate at the molecular level how MRSA epidemics may emerge and spread. Moreover, their study identifies a potential target for novel therapeutics. |
| Dentures' Biofilm Eradicated by CHG, Microwave Irradiation | Researchers in Brazil say that biofilms growing on dentures can be eradicated by a dip in CHG and by microwave irradiation. Methicillin-resistant Staphylococcus aureus (MRSA) biofilm on dentures can be aspirated, thus causing infections such as aspiration pneumonia. The researchers evaluated the efficacy of two disinfectant solutions and microwave irradiation in disinfecting complete dentures contaminated with MRSA. |

| Fatal Flu Cluster in Maryland Highlights Dangerous | Recently, a cluster of 3 deaths and 1 case of severe pneumonia were reported in a single family in Calvert County, Maryland. Diagnostic testing confirmed influenza H3N2 in all 4 patients and methicillin-resistant Staphylococcus aureus (MRSA) in at least 2. While it is unusual to see such a dramatic cluster of severe disease in one family, death from H3N2 influenza complicated by secondary MRSA pneumonia is not surprising. S. aureus, including MRSA, is well known to complicate influenza. During the 1968 H3N2 influenza pandemic, S. aureus pneumonia was a lethal cofactor in many cases. |
| MRSA Infection Rates Decline From Infection Control Certification | A new study, in the March issue of the American Journal of Infection Control , reveals that hospitals with a board certified director in infection prevention and control have substantially lower rates of methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSI), compared to hospitals that are not led by a certified professional. MRSA is a form of staph bacteria, which is resilient to certain antibiotics and can cause serious infections. |
| Study suggests use of antimicrobial scrubs may reduce bacterial burden on health care worker apparel | The use of antimicrobial impregnated scrubs combined with good hand hygiene is effective in reducing the burden of Methicillin-Resistant Staphylococcus Aureus (MRSA) on health care workers’ apparel and may potentially play a role in decreasing the risk of MRSA transmission to patients, according to a new study from Virginia Commonwealth University researchers. |
| Researchers Explore MRSA Prevalence in Europe | During the past two decades, methicillin-resistant Staphylococcus aureus (MRSA) has become increasingly common as a source of nosocomial infections. Most studies of MRSA surveillance were performed during outbreaks, so that results are not applicable to settings in which MRSA is endemic. |
MRSA: From a Nosocomial Pathogen to an Omnipresent Source of Infection
| The total incidence of nosocomial MRSA infections in Germany has stabilized after a substantial rise in the 1990s. Important risk factors for the acquisition of CA-MRSA include travel to high-prevalence areas, such as the United States, and close contact with people who are infected with CA-MRSA. The identification of individual areas with an increased prevalence of CA-MRSA in Europe does, however, make the occurrence of CA-MRSA increasingly likely. |
