NOBEL PRIZE WINNER CALLS FOR PATHOGEN SPECIFIC DRUGS

  • Ada. E. Yonath (Winner of Nobel Prize for Chemistry in 2009) delivered a talk in 107th Indian Science Congress
  • She said – Concerns surrounding anti-biotic use, including environmental hazards and the appearance of multi-drug resistant bacteria can be minimised by designing antibiotics that are specific to each species of pathogen, instead of using the broad-range antibiotics that are currently favoured.
  • The danger of antibiotics is the potential damage that they cause to the microbiome. Changes to the human microbiome can cause diseases.

What is Multi drug resistance?

  • Multiple drug resistance (MDR), multidrug resistance or multi-resistance is antimicrobial resistance shown by a species of microorganism to multiple antimicrobial drugs.
  • The types most threatening to public health are MDR bacteria that resist multiple antibiotics; other types include MDR viruses, parasites (resistant to multiple antifungal, antiviral, and antiparasitic drugs of a wide chemical variety).
  • Recognizing different degrees of MDR, the terms extensively drug resistant (XDR) and pandrug-resistant (PDR) have been introduced.
