Hello buddy..
Harshi this side..
As we know bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, Antibiotic resistance continues to expand for a multitude of reasons, including over-prescription of antibiotics by physicians, non-completion of prescribed antibiotic treatments by patients, use of antibiotics in animals as growth enhancers (primarily by the food industry), increased international travel, and poor hospital hygiene
An antibiotic kills a bacterial cell by simply disrupting a critical function. This is achieved in the cell in much the same way that a saboteur can cause a massive jetliner to crash by simply cutting the hydraulic lines.
The antibiotic binds to a protein so that the protein cannot function properly. The normal protein is usually involved in copying the DNA, making proteins, or making the bacterial cell wall—all important functions for the bacteria to grow and reproduce.
If the bacteria have a mutation in the DNA which codes for one of those proteins, the antibiotic cannot bind to the altered protein; and the mutant bacteria survive. In the presence of antibiotics, the process of natural selection will occur, favoring the survival and reproduction of the mutant bacteria. (The mutant bacteria are better able to survive in the presence of the antibiotic and will continue to cause illness in the patient.)
Hope it helps you buddy
