Bacteria Essay

The Cause and Effects of Tuberculosis What are the cause and effects of tuberculosis? Tuberculosis is a disease caused by a bacterium. These bacteria mostly infect the lungs, but also they can infect the other parts of the body like the brain, spine, and kidney. (1,4) If the tuberculosis bacteria are active, they will cause the death of the tissue of organs that have been infected. Tuberculosis is one of a few diseases that "have caused so much distressing illness for centuries and claimed so…

Professor Stuart B. Levy a physician from Tufts University affirms that the more antibiotics are used, the more resistance develops, demonstrating the fact that resistance is a product of evolution, and the more bacteria that are exposed to antimicrobials, the more will resistance be spread and…

gastrointestinal tract is comprised of about four million bacterial genes with more than 95% located in the large intestine (Galland, 2014). The gastrointestinal microbiota varies along the tract at longitudinal levels and horizontal levels due to particular bacteria attaching to the epithelium in the lumen (Todar, 2012). With DNA sequencing and metagenomic studies becoming increasingly popular, the concept of identifying bacterial colonies throughout the gastrointestinal tract is rising in…

Bacteriophages are the viruses of bacteria. They are a sequence of genomes which rotate from one bacterium to the next encased by capsids which are protein shells, which kill the bacteria in the process. Bacteriophages are immensely important to evolution and ecology of bacteria. They have colossal impacts on the carbon cycle. Phages also contribute to biology's comprehension of life at a molecular level. In addition, bacteriophages were essential to the evolution of genetic engineering. Phage…

Gram-negative bacteria". This means that during a Gram staining test the Legionella doesn't keep the pink dye. The reasoning behind this is because of the "cell wall composed of a thin layer of [peptidoglycan]" (Medicinenet.com). A counter stain is later added to make sure the bacteria being tested is surely Gram-negative. Legionnaires' disease is caused by the Legionella bacteria. In order to acquire the disease you must first obtain the Legionella bacteria. The spread of the bacteria can be…

for a viral infection. Another type of selective pressure is not completing a full prescription. If a patient stops taking an antibiotic before they should, all of the disease causing bacteria may not be dead yet. This greatly increases the chance of recurrence and a greater chance…

1. The biggest potential source of contamination of the locations we tested in the Distribution of Microorganisms would have to be the floor of the lab. The reason why this is the biggest potential source of contamination is because multiple people are coming in everyday from the outside world, bringing in microorganisms from the outside into the lab. And although we sanitize the counter and all the spaces that we work around, we don’t take precautions to necessarily clean the floor, making it…

teichoic acids that used by bacteria in cell wall synthesis. Teixobactin will form a stoichiometric complex by binding to a highly conserved motif of…

These bacterial cells literally almost do everything, from digesting our food, making our vitamins, keeping us healthy, etc. This is why we are considered 90% prokaryotic, due to the huge amount of bacterial cells within us (Bassler, 2009). 2. A bacteria called riboflavin that is found heavily in children in Malawi and Venezuela has been shown to extract all the nutrients…

microbiologists are diligently working on to find out how to stop these resistant bacteria. By finding out how these bacteria are becoming more and more resistant to outside sources we will find out how to better stop them. Through research, we have already found that it is very important for healthcare workers to wash their hands in between patients and that we carry bacteria in and on our bodies at all times. Resistant bacteria have now become a public health safety issue and any research that…
