Antibiotic resistance.
ANTIBIOTICS Vs. BACTERIA
Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply. Antibiotics have provided mankind with the means to treat many common bacterial infections efficiently. However, massive use of antibiotics since their introduction as medicines has led to increased occurrence and spread of bacteria that are resistant to antibiotics. That is, the medicine will no longer kill the bacteria. Antibiotics do NOT work on viruses like Covid.
The Rise of Resistant Bacteria
Antibiotic resistance is the ability of bacteria to protect themselves against the effects of an antibiotic. In the presence of the antibiotic, resistant bacteria will survive and increase in numbers. From a clinical perspective, resistance means that a bacterial colony can continue to grow even when being treated with a typical dose of antibiotics
There are two ways that bacteria can acquire antibiotic resistance
1. Mutations in the bacterial DNA may provide resistance by chance
2. Alternatively, they can receive resistance genes from other bacteria nearby.
Once a bacterium has an antibiotic resistance gene, it can be passed on to coming generations as the bacterium divides.
HOW ANTIBIOTIC RESISTANCE HAPPENS Nornal bacterium/Resistant bacterium/Dead bacterium
• Lots of germs and some are drug resistant
• Antibiotics kill the bacteria causing the illnes as well as the good bacteria protecting the body from infection
•The drug resistant bacteria is now able to grow and take over
• some bacteria give their drug resistance to other bacteria
Bacteria are becoming resistant to antibiotics. What is happening to the antibiotics that are being used by doctors? (1 point)
• They are becoming more effective in fighting bacteria
• They are becoming less effective in fighting bacteria
• [They no longer work at all
• They are becoming deadly
What is the name of the medicines designed to fight bacterial infections? (1 point)
• Antidiuretics
• Antihistamines
• Antidepressants
• Antiplotics

When the antibiotics don't kill the resistant bacteria, what happens to the next generations of bacteria? (1 point)
• Even though they are the "babies" of the resistant bacteria, they DO NOT get resistance gene and are unable to survive against the antibiotics.
• Since they are the "babies" of the resistant bacteria, they also have the resistance gene and are able to survive against the antibiotics. Then they have "babies" that are also resistant, and the number of resistant bacteria grows ano grows.
