An international team of scientists has identified a new kind of “superbug” -- or strong bacteria -- that has made people sick. They link the development of the superbug to the use of antibiotic drugs in farm animals. The scientists say this new strain of Methicillin-resistant Staphylococcus aureus -- known as MRSA sickened at least 10 people in Denmark. They said the bacteria is resistant to several antibiotics and can kill chickens. This strain is not found in Denmark. The researchers believe the Danes likely got sick from it by eating or being close to imported chicken. Most people do not get MRSA from animals used as food. The bacteria usually spreads through person-to-person contact in hospitals or other buildings where people live in small, crowded spaces. Farm workers have a higher risk of staph infections. The researchers compared the strains of MRSA in the 10 Danes to staph infections in other people and in livestock. They found the strain came from poultry.
