Chalmers University of Technology researchers have determined that significant genetic transfer between bacteria in our ecosystems and humans may be linked to pathogenic bacteria in humans developing resistance to antibiotics.
This has been difficult to explain because although conjugation is very common, we’ve thought that there was a distinct limitation for which bacterial species can transfer plasmids to each other.”.
The work revealed the number of oriT regions might be almost eight times higher than those found with the standard method used today; the number of mobile plasmids may be twice as high as previously known; and the number of bacterial species possessing mobile plasmids may be almost twice as high as previously known.
