Resistant bacteria

  • Worrying traces of resistant bacteria in air

    Two photos taken in the same location in Beijing in August 2005. The photograph on the left was taken after it had rained for two days. The right photograph shows smog covering Beijing in what would otherwise be a sunny day.

    Polluted city air has now been identified as a possible means of transmission for resistant bacteria. Researchers in Gothenburg have shown that air samples from Beijing contain DNA from genes that make bacteria resistant to the most powerful antibiotics we have. “This may be a more important means of transmission than previously thought,” says Joakim Larsson, a professor at Sahlgrenska Academy and director of the Centre for Antibiotic Resistance Research at the University of Gothenburg.
