Antibiotic resistance is a process which occurs, when an antibiotic has lost its ability to control or kill bacterial growth or when reduces the effectiveness of chemicals, drugs or other agents that are designed to cure or prevent the infections.

Antibiotics are the medicines or drugs used for the prevention and treatment of bacterial infections. It is the natural phenomenon in which a bacteria that can resist antibiotics have more chances of survival.
There is some resistance that occurs without human action in which a bacteria can produce and use antibiotics against other bacteria which leads to low-level of natural selection for antibiotic resistance.
Causes of Antibiotic Resistance
Generally, some bacteria are naturally resistant to a few types of antibiotics in two ways such as genetic mutation and by acquiring resistance from another bacterium. People Also Like: How to Protect Your Family From Eye Infections
There are different genetic mutations in different types of resistance like some mutations enable the bacteria to produce potent chemicals or enzymes which helps in inactivating the antibiotics.
Bacteria can also acquire antibiotic resistance genes from other bacteria through a process known as conjugation in which it can transfer genetic material such as genes encoding. Viruses are another mechanism for passing resistance traits between bacterias.
Antibiotic Resistance Examples
There are several bacterias that are resistant to antibiotics, including methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Mycobacterium tuberculosis (MDR-TB), and penicillin-resistant Enterococcus. MDR-TB is dangerous because it requires aggressive treatment by using a combination of five different drugs.
List of Antibiotic Resistance Bacterias
- Staphylococcus aureus (MRSA) that cause pneumonia, and flesh-eating disease.
- Burkholderia cepacia that cause pneumonia.
- Pseudomonas aeruginosa that cause pneumonia and various infections.
- Clostridium difficile that causes diarrhea.
- Klebsiella pneumonia that causes lung infections and pneumonia.
- Escherichia coli (E. coli) that cause diarrhea, meningitis, and urinary tract infection.
- Acinetobacter baumannii that cause pneumonia, urinary tract infection, and meningitis.
- Mycobacterium tuberculosis that causes tuberculosis.
- Neisseria gonorrhoeae that cause gonorrhea.
- Streptococcus pyogenes that cause a sore throat and skin disorders.
Antibiotic resistance is a naturally occurring process in which an antibiotic lost its ability to control or kill bacterial growth.
It can be done through genetic mutation or by acquiring resistance from another bacterium. Bacterias can use and produce antibiotics against other bacteria, resulting in low-level of natural selection for antibiotic resistance.
