Out of the 32 strains of MRSA, 17 were vancomycin sensitive, 11 were intermediate and 4 were VRSA
All 14 VRSA
identified in the United States appear to have independently acquired the vanA operon.
isolates simultaneously with vanA and vanB genes have been found only in the mentioned study.
State health officials were continuing to encourage health professionals to use appropriate infection control practices such as frequent handwashing and wearing masks to reduce the spread of VRSA
Should the VRSA
organism become widespread, this could have serious implications not only for public health, but also for nurses working with those infected.
The patient's VRSA
infection was treated with daptomycin for 6 weeks.
Scientists have now determined the genome sequence for all 12 available VRSA
Patients in the 1CU and other critically ill patients are at high risk for co-colonization with MRSA and VRE and, possibly, VRSA
, since both organisms are endemic and associated with increased illness severity (11,12).
After notification and subsequent analysis by the New York State Department of Health (NYSDOH), the isolate was forwarded to CDC, where it was confirmed to be VRSA
(vancomycin MIC = 64 [micro]g/mL, using the National Committee for Clinical Laboratory Standards broth microdilution reference method).
Adherence to guidelines and an approach that integrates health care and public health systems are needed to prevent emergence of multidrug-resistant organisms, the investigators said, noting that isolates of suspected VRSA
should be saved, resistance status confirmed, and test results reported to the National Center for Infectious Diseases (800-893-0485 or search@cdc.
The first case of VRSA
was recorded in a 40-year-old man being treated for diabetes in Michigan three months ago.
Infections with antibiotic resistant "Superbugs", such as VRE and VRSA
, are serious problems for patients and hospitals worldwide.
will be the partners exclusive, integrated retail mall developer, owner, operator and asset manager for India.
Another strand was treatable by the antibiotic vancomycm, but even this cannot treat VRSA
case is the first reported since 2007, when two cases were reported, according to CDC data.
