Frequency of heteroresistance has been greatly underestimated, study finds

When antibiotics are used to treat bacteria susceptible to them, the treatment usually works. Nevertheless, the antibiotic chosen is sometimes ineffective. One of the reasons for this is heteroresistance, a phenomenon explored in depth by Uppsala and Emory University researchers in a new study.
