      Antibiotics Can Put Some Bacteria to Sleep

      Business Standard reports that in a breakthrough, scientists from Hebrew University have for the first time identified a mechanism by which some bacteria are able to survive antibacterial treatment.

      In addition to the known phenomenon by which some bacteria achieve resistance to antibiotics through mutation, there are other types of bacteria, known as "persistent bacteria", says Business Standard.

      These bacteria are not resistant to the antibiotics but simply continue to exist in a dormant or inactive state while exposed to antibacterial treatment. They later "awaken" when that treatment is over. Business Standard explains that the antibiotics actually cause them to release the HipA toxin, which signals the germs to become temporarily dormant.
