Antibiotics
By:Alex Pettis
Main Idea
- Also called antibacterials
- Can be prescribed by a doctor
- Discovered by Alexander Fleming in 1928
- Kills bacteria by interfering with its formation of the cell wall or the cell contents
Antibiotics are medicines used to treat infectious diseases caused by bacteria. They were discovered by Alexander Fleming in 1928, who had discovered penicillin. Antibiotics work because they kill the bacteria in the body by interfering with its cell wall formation or the contents of the cell. Antibiotics only work on bacterial infections and not viral infections. If you have a bacterial infection and go to the doctor, they can prescribe the antibiotic that is needed. Some antibiotics will not work because the bacteria in the body is more powerful than the antibiotic. These are known as antibiotic resistant bacteria. Some reasons antibiotics are resistant to bacteria in the body are: because people don’t take the antibiotic as prescribed, using them when not needed or using the same antibiotic too frequently. If the bacteria is resistant to the antibiotic, then a doctor may prescribe a different antibiotic which would be the way to get around the antibiotic resistant bacteria.
I learned that antibiotics are only used to treat bacterial infections and not viral infections. Also, when learning about antibiotics there is so much to take into consideration when taking an antibiotic. Something that surprised me was that when looking at the list of antibiotics each antibiotic has a more specific type such as penicillin has penicillin V potassium, amoxicillin and amoxicillin/clavulanate (Augmentin). Antibiotics were something that I already knew some things about, but not everything that was written here. I liked this objective a lot because it is good to know that there is a thing that can treat bacterial infections in the body. Antibiotics can be applied outside of biology because if you need to take an antibiotic you will know what can happen if you don’t take them right.

Great blog!! Is there a way to be antibiotic resistant from a certain and later on be able to use it again without being antibiotic resistant?
ReplyDeleteYes, if you don't use it for a while, then your body will allow you to use it again.
DeleteAwesome blog!!! Great information and very well organized!! The only question I have is how many prescriptions can a person get at one time?
ReplyDeleteGenerally it's one at time for a specific amount of time.
DeleteDepends on what illness you have, I've been prescribed two to three at a time before.

ReplyDeleteWhat is the main drug bacteria are resisting?
ReplyDeleteThe two main drugs are Staphylococcus aureus and Neisseria gonorrhoeae.
ReplyDeleteGreat Blog, I did not know a lot of those things about antibiotics, My question is if the antibiotics we take are becoming less effective because of there use in food why do we still use them in food and animals?

DeleteActually, we use different antibiotics for food and animals but we would still want use an antibiotic in food and animals because they have problems just like humans. They may have different problems but use the different antibiotics in the same way as a human does. If an animal got sick and we did not use an antibiotic to treat them then the food that comes from that animal would contain the same bacterial infection as the animal. This then would lead to things like world hunger and a decrease in the population because of the decrease in the world's food supply.
