How is antibiotic resistance developed?
The main cause of antibiotic resistance is antibiotic use.
When we use antibiotics, some bacteria die but resistant bacteria can survive and even multiply.
The overuse of antibiotics makes resistant bacteria more common.
The more we use antibiotics, the more chances bacteria have to become resistant to them..
How is biotechnology used in antibiotics?
Antibiotics are biotechnological products that inhibit bacterial growth or kill bacteria.
They are naturally produced by microorganisms, such as fungi, to attain an advantage over bacterial populations.
Antibiotics are produced on a large scale by cultivating and manipulating fungal cells..
What are the 4 types of antibiotic resistance?
Antimicrobial resistance mechanisms fall into four main categories: (1) limiting uptake of a drug; (2) modifying a drug target; (3) inactivating a drug; (4) active drug efflux..
What is antibiotic resistance in biotechnology?
Some genetically modified plants contain genes that make the plant resistant to certain antibiotics.
Scientists often add these resistant genes during genetic modification so that the GM plants and cells can be distinguished from non-GM ones..
What is the biological cause antibiotic resistance?
Biological Mutations
Through mutation and selection, bacteria can develop defense mechanisms against antibiotics.
For example, some bacteria have developed biochemical “pumps” that can remove an antibiotic before it reaches its target, while others have evolved to produce enzymes to inactivate the antibiotic..
What is the main reason antibiotic resistance occurs?

What is the role of biotechnology in antibiotics?

Where is antibiotic resistance found?
AMR occurs naturally over time, usually through genetic changes.
Antimicrobial resistant organisms are found in people, animals, food, plants and the environment (in water, soil and air).
They can spread from person to person or between people and animals, including from food of animal origin..
- Abstract.
The three fundamental mechanisms of antimicrobial resistance are (1) enzymatic degradation of antibacterial drugs, (2) alteration of bacterial proteins that are antimicrobial targets, and (3) changes in membrane permeability to antibiotics. - Animals fed on GM plants readily digest DNA, including that which makes up antibiotic resistance genes.
Although this process may be incomplete it is unlikely that these antibiotic resistance genes would be able to “escape” into the environment through this route, due to a series of well-established barriers. - Biological Mutations
Since bacteria are extremely numerous, random mutation of bacterial DNA generates a wide variety of genetic changes.
Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. - Biological Mutations
