Bacteria and Fungi Research Paper

It 's bad or infectious bacteria that cause illness as they rapidly reproduce and produce a toxin that kills or mutates cells, bacteria is also self sufficient.

There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient, so as to know how it can be treated, to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that I have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium.

Citrobacter Freundii is a species of bacteria that can be potentially harmful to humans. It is known to cause meningitis by protruding into the brain and replicating itself (1). The Citrobacter species has also been found as a cause of some urinary tract infections, diarrhea, and even gastrointestinal diseases and symptoms (3). C. Freundii can be located in a wide variety of soils and water (3). Lastly, it is also the cause of many nosocomial infections due to its presence in water (1).

Bacteria are prokaryotic, and if you were to observe the two cells under a light microscope, you could distinguish their differences. The biggest distinguishment you can make while carefully observing the two cells, is the lack of a nucleus in a prokaryotic cell as compared to a eukaryotic. Prokaryotes also lack any membrane-bound organelles.

The Gram-positive cell wall is composed of peptidoglycans, a thick layer of protein-sugar complexes taking up 60-90% of their cell wall. Peptidoglycan is composed of two glucose derivatives, N-acetylmuramic acid and N-acetylglucosamine alternated and cross-linked by tetrapeptides that is composed of L-alanine, D-glutamine, L-lysine

Bacterial cells and eukaryotes both have a cell wall. The cell wall is what gives the cells its unique shape and size. The cell wall in bacterial cells are made up of carbohydrates, proteins and peptidoglycan. The cell wall in bacteria protects the cell from damages to the cell and has a inelastic shape just outside the plasma membrane. The cell wall of

As many people may know, bacteria can be either harmful or helpful. The damage on your body can vary by the harmful bacteria. The damage can be as little as a cough all the way to death depending on the bacteria and amount of it. That is why it is really important to for your doctor to prescribe you medicine when you are sick or coming up with something. The reason any doctor emphasizes the importance of finishing the prescribed bottle of antibiotics relates to all 5 steps for evolution by natural selection. The first step one is over reproduction. All animals have the ability to produce more offspring than can possibly survive. This could be critically dangerous for humans because if the bacteria duplicate numerously then the antibiotics might not even be able to kill all bacteria. Another step

to keep the inner workings of the bacteria safe. Without a cell wall, the bacteria could

The body fights infection using the immune system, which is made up of millions of cells including T cells and B cells. An important feature of the immune system is that it is much stronger when fighting a disease which it has already fought against before. It has a memory.

Bacteria can be a scary thing, but some people do not even know what bacteria is but doctors have created antibiotics to destroy it. “Many people are unaware what bacteria are and how antibiotics control them.”(Voss, Bristol) Basically bacteria a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease. Antibiotics are used to destroy bacteria, but if a person is prescribed too many antibiotics they may become immune to antibiotics forever and have to live without a strong immune system. Antibiotics attacks bacteria by preventing it from building a wall to defend itself from the body's immune system. So the body’s immune system can easily kill the bacteria.

The Cell wall is a hard, rigid layer that surrounds the cells of fungi, bacteria, and plants. The cell wall is located just beyond the cell membrane. The key purpose of the cell wall is to provide structure, flexible power, structure support,

Bacillus are rod shaped, prokaryotic cells, they form spores (gram positive and gram negative) on gram staining. Escherichia are rod shaped, prokaryotic cells, however they

Bacteria, mold, and yeast, can cause food to spoil. Microorganisms that break down fats in unsalted butter can cause it to become rancid. Bacteria that breaks down protein in meat and results in foul odors. If milk is kept too long, it will sour. Bacteria that have survived pasteurization grow in the milk and produce acid from the lactose that is naturally present in the milk. One important cause of food spoilage is air and oxygen. Oxygen can cause food spoilage in several ways. It can provide conditions that will build up the growth of microorganisms; it can cause damage to foods with the help of enzymes: and it can cause oxidation. When temperatures are not well controlled, food can

If you have inflammation or infection, the doctor might prescribe you some medication to reduce symptoms and kill bacteria or calm the tissue. However, the use of Antibiotics can lead to antibiotic resistant bacteria in your body and might also disturb the good and bad bacterial

Life on this planet began with microorganisms. Through millions of years microorganisms have found ways to successfully adapt and survive. These adaptations have created a wide biodiversity, allowing them to basically populate in all places. Why are these microbes so important? Because they shape the history of our world. Some microbes can be deathly to humans while some others are favorable, for example, bacteria that lives in the gut of both humans and animals and helps during the process of digestion (Alfred Brown & Heidi Smith, 2006). Understanding these interactions help scientists to find ways to protect humans from potential deathly pathogens. In order to observe microbes, microscope proficiency and microorganisms’ identification are crucial skills in a microbiology lab. During this laboratory session, samples of environmental and human organisms were inoculated into two different rich media and incubated to their according temperature. After this, appropriate use and calibration of the microscope was performed. Lastly, morphology and size of different species of bacteria, algae, fungi and protozoan were recorded.
