  1. Bacteria Use Toxin to HibernateA research group at Aarhus Univ. has gained unique insight into how bacteria control the amount of toxin in their cells. The new findings can eventually lead to the development of novel forms of treatment for bacterial infections. Many pathogenic bacteria are able to go into a dormant state by producing persister cells that are not susceptible to conventional antibiotics. This causes serious problems in the treatment of life-threatening diseases such as tuberculosis, where the presence of persister cells often leads to a resurgence of infection following medical treatment.At the molecular level, the formation of persister cells is because of the presence of toxins that are produced by the bacteria themselves, and which enable them to enter the dormant state. During this hibernation period, the bacteria constantly regulate the amount of toxin at exactly the same level and thus maintain the dormant state.Read more: http://www.laboratoryequipment.com/news/2012/09/bacteria-use-toxin-hibernate
