Studies highlight MRSA evolution and resilience

A single strain of an evolving bacterium has been responsible for most of the community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections. – Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain-USA300-of an evolving bacterium that has spread with “extraordinary transmissibility” throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists. CA-MRSA, an emerging public health concern, typically causes readily treatable soft-tissue infections such as boils, but also can lead to life-threatening conditions that are difficult to treat.

Gay men vulnerable to infectious MRSA superbug bacteria

A new report in the Annals of Internal Medicine is reporting that a super resistant bacteria MRSA superbug is spreading in gay communities. – Sexually active gay men are many times more likely than others to acquire a new, highly antibiotic-resistant strain of the so-called MRSA bacteria widely know as the “superbug,” a UCSF-led study shows.

Quick Test For Drug-Resistant Staph Infections MRSA

The U.S. Food and Drug Administration (FDA) approved the first rapid blood test for the drug-resistant staph bacterium known as MRSA (methicillin-resistant Staphylococcus aureus). – The U.S. Food and Drug Administration (FDA) announced it has cleared for marketing the first rapid blood test for the drug-resistant staph bacterium known as MRSA (methicillin-resistant Staphylococcus aureus), which can cause potentially deadly infections.
