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.
