The appearance of antibiotic-resistant Bacteria is an example of natural evolution. Some bacteria have developed resistance to antibiotics that were once commonly used to treat them.
For example: Staphylococcus aureus and Neisseria gonorrhoeae are resistant to benzylpenicillin with the passage of time. Before this, these infections were usually controlled by penicillin.
The most critical concern with antibiotic resistance is that some bacteria have become resistant to almost all of the easily available antibiotics. These bacteria cause serious disease.
Important examples are:
1. methicillin-resistant Staphylococcus aureus (MRSA)
2. vancomycin-resistant Enterococcus (VRE)
3. multi-drug-resistant Mycobacterium tuberculosis (MDR-TB)
4. carbapenem-resistant Enterobacteriaceae (CRE) gut bacteria
