Superbugs

Definition

Superbugs are strains of bacteria that have developed resistance to multiple antibiotics, making them difficult to treat. They arise due to genetic mutations and the misuse or overuse of antimicrobial drugs.

5 Must Know Facts For Your Next Test

1. Superbugs can survive antibiotic treatments that would normally kill them.
2. Examples include Methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Mycobacterium tuberculosis (MDR-TB).
3. Overuse of antibiotics in healthcare and agriculture accelerates the development of superbugs.
4. Standard staining techniques may not differentiate superbugs from non-resistant strains, requiring additional molecular methods for identification.
5. Combating superbugs requires a combination of new drug development, better diagnostic tools, and strict infection control measures.
