New study is an advance toward preventing a 'post-antibiotic era'

New research may help to overcome life-threatening antibiotic-resistant bacteria in what the World Health Organization warns could become a 'post-antibiotic era.' Biologists combined different classes of antibiotics to kill E. coli bacteria in their laboratory and found that certain combinations of three antibiotics are surprisingly effective in killing the bacteria and may be helpful in slowing the evolution of resistance to bacteria.
