American College of Physicians study says staph infection more common among siblings

research

Washington : An American College of Physicians study has come to the conclusion that staph infections are more common among siblings.

Researchers found that the incidence of Staphylococcus Aureus Bacteremia or staph infection, has increased over the past few decades, with antibiotic resistance compounding the problem.

Animal studies have shown a link between host genetics and staph infection, but whether human host genetics in general are associated with the risk for acquiring staph infection is unclear.

Researchers reviewed a national registry in Denmark to determine whether a history of S. aureus bacteremia in first-degree relatives is associated with an increased risk for microbiologically confirmed S. aureus bacteremia.

They found that having a first-degree relative hospitalized with confirmed staph infection significantly increased a person’s risk for the disease.

The risk was significantly higher if the infected patient was a sibling than a parent.

According to the researchers, the results are unlikely to be explained by direct transmission of the pathogen because more than 80 percent of exposed individuals acquiring staph were infected with a strain genetically different from the infected relative.

The study is published in the journal Annals of Internal Medicine. (ANI)
