About Abaucin:
- It is known to compromise the normal function of a protein called CCR2.
- It appears to work by disrupting lipoprotein trafficking in A. baumannii.
- Based on genetic studies, the researchers believe that abaucin could be preventing lipoprotein produced inside the bacteria from moving to the outer membrane.
- Abaucin is also “species-selective”, it only disrupts the growth of A. baumannii, not other Gram-negative bacteria.
What is an Acinetobacter baumanni?
- It is a Gram-negative bacteria, which means it has a protective outer membrane that allows it to resist antibiotics.
- It has been associated with hospital-acquired infections in India.
- It was acknowledged to be a “red alert” pathogen because of its exceptional ability to develop resistance to all currently available antibiotics.
Q1) What is Gram-negative bacteria?
Gram-negative bacteria are a group of bacteria that are characterized by their response to the Gram staining technique, which is a method used to classify bacteria into two broad categories: Gram-positive and Gram-negative. Gram-negative bacteria have a unique cell wall structure that distinguishes them from Gram-positive bacteria.
