Scientists Have Discovered A New Kind Of Staphylococcus
Scientists Have Discovered A New Kind Of Staphylococcus. Potentially deleterious staph bacteria can hide deep inside the nose, a small new muse about finds. Researchers tested 12 healthy people and found that formerly overlooked sites intensely within the nose may be reservoirs for Staphylococcus aureus, which is a major cause of disease. Nearly half of S aureus strains are antibiotic-resistant more about the author. It's been known that S aureus can reside on the veneer and at sites quieten down in the nose. Although there are ways to eliminate the bacteria, it typically returns in weeks or months. This strange finding that the bacteria can be present further inside the nose may explain why this happens, the Stanford University School of Medicine researchers said spray. "About one-third of all commoners are persistent S aureus carriers, another third are incidental carriers and a remaining third don't seem to carry S aureus at all," reflect on senior author Dr David Relman, a professor of medicine and microbiology and immunology, said in a university telecast release. And "Not everyone who carries S aureus gets sick. When they're out walking the streets and otherwise healthy, attempts to rid them of their S aureus are not necessary, and even occasionally futile," said Relman, who also is superintendent of the infectious disease section at Veterans Affairs Palo Alto Health Care System, in California here. "But once a porter enters a polyclinic with an underlying illness or a weakened immune system or a high likelihood of undergoing skin-penetrating procedures, S aureus freightage is a major liability. If S aureus gets into the bloodstream through a wound, cut or catheter placement, it can cause potentially life-threatening problems such as sepsis, pneumonia or infection of feeling valves. Relman and his colleagues also found that a type of bacteria called Corynebacterium pseudodiphtheriticum may fence with S aureus at the sites deep within the nose. It's possible that C pseudodiphtheriticum - or some molecular by-product it produces - may prove useful in countering S aureus infections, the researchers said bonuses.
