Strains of potentially deadly, antibiotic-resistant Staphylococcus aureus bacteria show seasonal infection preferences, putting children at greater risk in summer and seniors at greater risk in winter, according to results of a new nationwide study led by a Johns Hopkins researcher. http://medicalxpress.com/news/2013-02-strains-antibiotic-resistant-staph-bacteria-seasonal.html Diseases, Conditions, Syndromes Thu, 28 Feb 2013 04:13:58 EST news281247228 Scientists have used DNA sequencing for the first time to effectively track the spread of, and ultimately contain, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA), according to new research published in The Lancet Infectious Diseases. http://medicalxpress.com/news/2012-11-mrsa-outbreak-dna-sequencing.html Diseases, Conditions, Syndromes Tue, 13 Nov 2012 18:30:01 EST news272044480 A team led by researchers at the University of Maryland School of Public Health has found that the "superbug" methicillin-resistant Staphylococcus aureus (MRSA) is prevalent at several U.S. wastewater treatment plants (WWTPs). MRSA is well known for causing difficult-to-treat and potentially fatal bacterial infections in hospital patients, but since the late 1990s it has also been infecting otherwise healthy people in community settings. http://medicalxpress.com/news/2012-11-superbug-mrsa-wastewater-treatment.html Diseases, Conditions, Syndromes Mon, 05 Nov 2012 16:36:53 EST news271355798 (Medical Xpress)—In two separate studies, researchers at The Ohio State University Wexner Medical Center have discovered a new class of treatment against methicillin-resistant Staphylococcus aureus (MRSA) as well as evidence of a growing need to quickly genotype individual strains of the organism most commonly referred to as the "superbug." http://medicalxpress.com/news/2012-10-mrsa-class-drugs-effective-superbug.html Diseases, Conditions, Syndromes Wed, 10 Oct 2012 17:57:05 EST news269110601 People who live near livestock or in livestock farming communities may be at greater risk of acquiring, Methicillin-resistant Staphylococcus aureus (MRSA), according to a new study led by an international team of researchers from the Johns Hopkins Bloomberg School of Public Health, the Dutch Institute for Public Health and the Environment (RIVM) and VU University Medical Center in Amsterdam. A comparison of livestock density, place of residence and existing information on risk factors found that regional density of livestock is an important risk factor for nasal carriage of livestock-associated (LA) MRSA for persons with and without direct contact with livestock. The results are featured in the November issue of Emerging Infectious Diseases. http://medicalxpress.com/news/2012-10-livestock-mrsa.html Diseases, Conditions, Syndromes Wed, 10 Oct 2012 13:14:34 EST news269093643 An individual hospital's infection control efforts have a ripple effect on the prevalence of a deadly and highly infectious bacterium in hospitals throughout its surrounding region, a multi-center research group led by the University of Pittsburgh demonstrated in a computer simulation-based study. http://medicalxpress.com/news/2012-10-hospitals-cooperate-infection-fare.html Diseases, Conditions, Syndromes Tue, 09 Oct 2012 16:33:33 EST news269018988 Researchers at The Ohio State University have discovered a new class of treatment against methicillin-resistant Staphylococcus aureus (MRSA) as well as evidence of a growing need to quickly genotype individual strains of the organism most commonly referred to as the "superbug." http://medicalxpress.com/news/2012-10-class-anti-bacterial-drugs-mrsa.html Diseases, Conditions, Syndromes Tue, 02 Oct 2012 15:03:04 EST news268408972 Menachem Shoham, PhD, associate professor of biochemistry at Case Western Reserve University School of Medicine, has discovered novel antivirulence drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) and Streptococcus pyogenes, commonly referred to as strep, harmless by preventing the production of toxins that cause disease. The promising discovery was presented this week at the Interscience Conference on Antimicrobial Agents and Chemotherapy in San Francisco. http://medicalxpress.com/news/2012-09-non-antibiotic-agents-mrsa-common-strep.html Medical research Wed, 12 Sep 2012 13:38:53 EST news266675906 Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) doubled at academic medical centers in the U.S. between 2003 and 2008, according to a report published in the August issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. http://medicalxpress.com/news/2012-07-mrsa-cases-academic-hospitals-years.html Diseases, Conditions, Syndromes Thu, 26 Jul 2012 16:33:41 EST news262538908 In analysis that included more than 9 million Department of Defense nonactive and active duty personnel, the rates of both community-onset and hospital-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia decreased from 2005 to 2010, while the proportion of community-onset skin and soft tissue infections due to MRSA has more recently declined, according to a study in the July 4 issue of JAMA. http://medicalxpress.com/news/2012-07-community-onset-mrsa-infections-decline.html Diseases, Conditions, Syndromes Tue, 03 Jul 2012 16:32:27 EST news260551931 In a new study released today in New England Journal of Medicine, researchers demonstrate that whole genome sequencing can provide clinically relevant data on bacterial transmission within a timescale that can influence infection control and patient management. http://medicalxpress.com/news/2012-06-tracking-mrsa-real-highlights-benefits.html Genetics Wed, 13 Jun 2012 17:00:01 EST news258811176 Hospitalization rates in New York City for patients with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), a potentially deadly bacterial infection that is resistant to antibiotic treatment, more than tripled between 1997 and 2006, according to a report published in the July issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. http://medicalxpress.com/news/2012-06-community-acquired-mrsa-cases-york-city.html Diseases, Conditions, Syndromes Tue, 12 Jun 2012 12:13:32 EST news258721994 (HealthDay) -- Only about 1 percent of very low birth weight (VLBW) infants develop methicillin-resistant Staphylococcus aureus (MRSA) infections, and the morbidity and mortality are similar to that seen in infants with methicillin-susceptible S. aureus (MSSA) infections, according to a study published online March 12 in Pediatrics. http://medicalxpress.com/news/2012-03-staph-sepsis-mortality-preterm-infants.html Diseases, Conditions, Syndromes Mon, 12 Mar 2012 13:50:29 EST news250778988 Patients' ratings of hospitals tally with objective measures of the hospital's performance, according to an independent study published today in Archives of Internal Medicine. http://medicalxpress.com/news/2012-02-patients-online-hospital-outcomes.html Health Mon, 13 Feb 2012 16:00:13 EST news248370679
