NDM-1

♤ Recently, a new resistant strain of Klebsiella pneumoniae was detected in a Swedish patient of Indian origin. This produces an enzyme named New Delhi-metallo-beta-lactame-1 (NDM-1), which inactivates a broad range of beta-lactam antibiotics. Since this was first found in a patient who had undergone medical treatment in India, the researchers named it after New Delhi. The gene for NDM-1 can spread horizontally and at least twenty strains of bacteria, each resistant to one or many antibiotics, are now known.
