It takes around an hour for bacteria to have sex, in order to exchange almost the whole genome. In that sense, humans have a lot to learn from bacteria! this also explains why antibiotic resistance spreads so quickly, because the plasmid DNA is very mobile and is often present at hundreds of copies per bacterial cell. Farm animals are often fed a diet heavily laced with antibiotics, which causes antibiotic resistance to spread rapidly. However, plasmid DNA is very useful for DNA vaccines and gene therapeutics, two major classes of emerging biopharmaceuticals.
