Bacteria Episode II: Attack of the Antibiotics

 This is the era of the Bacteria Wars and the antibiotics(clone troopers) are losing against the bacteria(battle droids) because of the huge upgrade that mutated them into stronger bacteria(super battle droids) that allowed them to grow and thrive.  Just kidding. Anyway, this time we are gonna get more in depth about bacteria.


From last week, we learned about bacteria and what their characteristics are. Bacteria can be helpful and beneficial because bacteria can allow humans to digest their food properly. They can be ingredients in yogurt, cheese, etc. They can recycle dead organisms and decompose them. They can fix nitrogen which is a nutrient plants need. Believe it or not, some of the bacteria can be in some of the antibiotics. The antibiotics are fed to the animals even when they are not sick. This causes them to have growth hormones.    LINK

How nitrogen fixing bacteria benefits plants and animals is they turn atmospheric nitrogen into ammonia and they are inorganic compounds which the plants can utilize. How they benefit animals is that the nitrogen can go back to the atmosphere and can help with breaking down organisms by bacteria carrying it.

Pasteurization is partial sterilization of foods at a certain temperature that destroys harmful microorganisms. How it is important is it destroys disease inside of milk primarily and it adds to the longevity(how long it will be until it goes bad) from causing the milk to go bad.LINK

You can't escape bacteria beacause they are everywhere. Some bacteria can be harmful and can cause human disease. For example, the three bacterial infections are tuberculosis, pneumonia, and strep throat. Tuberculosis is caused by mycobacterium tuberculosis and the symptoms are coughing up blood ands loss of appetite. Strep throat is caused by streptococcus bacteria and the symptoms are high fever, sore throat, and fatigue. Pneumonia is caused by hemophilus influenzae and the symptoms are vomiting, shortness of breath, fever, and coughing. LINK

All of you guys may have heard of the word antibiotics. First of all let me explain what antibiotics are, antibiotics is what doctors developed to cure people that are sick. But over the years
antibiotics became less affective to bacteria, because one, the overuse of antibiotics became less useful and two, bacteria started to mutate and become resistant to antibiotics.







 
See ya guys later and have a merry christmas and a happy new year.

                Hello guys and welcome back to my latest blog post about the microscopic world of bacteria.:)


               Let's start off with what bacteria really is. Bacteria are microorganisms that are prokaryotic( as mentioned in my previous blog posts). The cell structure contains:

• pili- they have hair like structures that can transfer DNA to another bacteria.
• basal body- which can anchor the base of the flagellum and allows it to rotate.
• capsule- a layer in the outside of the cell wall.
• cell wall- a layer membrane outside of the plasma membrane LINK 
• cytoplasm- a jelly like substance that contains ribosomes and genetic material are located
• flagellum- a long whip like structure in which it allows the bacteria to move.
• plasma membrane- a membrane located inside the cell. It generates energy and transports chemicals
• ribosomes- small organelles rich in RNA.

Many bacteria come in all different shapes and sizes. The can be rod shaped, spiral shaped, or sphere shaped. The spiral shaped ones usully look like party streamers. They can move by using their whole body . Rod shaped bacteria look like bars. They move by using their flagellum or cilia. Finally, sphere shaped bacteria look like spheres and they use the same movement as the rod shaped ones.

Also fission is when two bacteria reproduce sexually or asexually (as mentioned in my previous posts) and split into more bacteria.

How bacteria obtain food and energy is thet they are heterotrophic, which means that they get food from other organisms. They can trap other organisms. They can make their own food(autotroph) by using photosynthesis. They can even make food and energy using the power of the sun.





You probably might be wondering about why eubacteria and archaebacteria are classified differently. Because they have different chemicals and RNA. Eubacteria can make their own food and they can add oxygen to the atmosphere.they can't live in extreme environments. Archaebacteria can consume or make their own food. They can survive in hostile environments like volcanos, acidic environments and deep ocean vents. Some of them can live inside of you. They can help break down the food in your intestines.





Well, see ya later.
