A group of scientists recently discovered a new antibiotic that can kill a deadly superbug called Acinetobacter baumannii.

About Acinetobactor Baumannii:

  • Acinetobacter is a group of bacteria(germs) commonly found in the environment, like in soil and water. 
  • While there are many types, the most common cause of infections is Acinetobacter baumannii, which accounts for most Acinetobacter infections in humans.
  • It is a Gram-negative bacteria that often displays multidrug resistance.
  • It can cause infections in the blood, urinary tract,and lungs (pneumonia), or in wounds in other parts of the body.
  • It can also “colonize” or live in a patient without causing infections or symptoms, especially in respiratory secretions (sputum) or open wounds.
  • These germs are frequent causes of hospital-acquired infections, especially in intensive care units (ICUs). 
  • It is highly contagious.

Gram-Positive vs. Gram-Negative Bacteria:

  • Gram-positive bacteria have cell walls made of a thick layer of peptidoglycan.
  • The cell walls of gram-negative bacteria contain only a thin layer of peptidoglycan, but they also have an outer membrane that is absent in gram-positive bacteria.
  • Gram staining is a technique that uses violet dye to distinguish between gram-positive and gram-negative bacteria.
  • If the bacteria are gram-positive, the thick, peptidoglycan layer in their cell walls will retain the dye and they will stain violet.
  • If the bacteria are gram-negative, the dye will leak out of the thin peptidoglycan layer, and the bacteria will stain red.


Q1) What is multidrug resistance?

Multidrug resistance (MDR) is a type of insensitivity developed by microorganisms to lethal doses of antibiotics. MDR has become a major concern for antibiotics regarding their efficacy against pathogenic diseases.
