Bacteria Essay

Microbiology is the study of small organisms and or non living particles that are unseen to the naked eye. The microbes range from bacteria, to protozoa, parasites to virus. After studying them, scientists are able to identify various illnesses that are associated with microbes. These microbes are either directly or indirectly involved in most diseases. These in retrospect to their names cause bacterial infections, parasitical infections, fungal infections and viral infections. However, although…

Biology Antibiotics Assignment Introduction Bacteria are microscopic prokaryotic cells, they are very common and are found in every habitat on earth (Introducing Microbes, n.d.). There are many harmless bacteria however bacteria are the cause of many diseases including salmonella, pneumonia and meningitis (Cynthia Haines,2013). To combat these diseases caused by bacteria in 1928 Alexander Discovered the first antibiotic, it was used to treat soldiers in ww2 with infections which could…

suggests that the size of the waist depends to a certain extent on bacteria that inhabit the intestine. How is it possible? In a study involving 900 Dutch adults, it was found that some intestinal bacteria could help determine not only body fat levels, but also blood concentrations of HDL (good) cholesterol and triglycerides. A close relationship! This is the first study to offer "solid evidence" linking intestinal bacteria with cholesterol and triglyceride levels, said Jingyuan Fu,…

infectious diseases. There are four type of microorganisms that causes infectious disease are bacteria, parasites, fungi and viruses. Microbiology laboratory has many sections and each section do many types of tests. The microbiology laboratory has many sections such as bacteriology, parasitology, virology and mycology. The microbiology laboratory is study the microorganism that cannot be seen by the eye such as bacteria and fungi to medical diagnosis.…

meningitis is contagious and prolonged close contact can spread the bacteria that cause meningitis. The bacteria can spread from person to person be the means of bodily fluids. In many instances, bacterial meningitis develops when bacteria get into the bloodstream from the sinuses, ears, or other part of the upper respiratory tract. The bacteria then travel through the bloodstream…

In medical or science field, biochemical test are used to identify unknown bacteria. In this case three test are essential to identify the unknown #63 and they are MAC agar test, BCP (lactose) broth and SIM deep medium/slant. Methods such as streak plate technique, aseptic technique, and proper handling of the microbe are necessary to apply when conducting these biochemical test. Contamination during the unknown lab project shows carelessness and may put patient in jeopardy due to incorrect…

microorganisims they act primarily against. Identification of the disease causing agent is essential for anti-microbial therapy . (Dasari Srilakshmi et al ; 2016 ) Tal sindoor has a broad spectrum anti–microbial activity against Gram positive, Gram negative bacteria and as well against fungi. Antimicrobial activity of the drug Tal Sindoor can be tested in 2 methods i.e. Gradient plate technique and Kirby-bauer method. Tal Sindoor has an effective anti-microbial activity against Pseudomonas…

lactic acid bacteria, Gram-negative bacteria, and wild yeasts/molds. This was accomplished by using a series of spread/pour plate dilutions with various media types that contained selective ingredients. By cross-referencing the different medias and comparing observations, the generalized groups of contaminants were able to be confidently conjectured. Growth was witnessed on DRBC, DRBC + CuSO4, and MRS agars. The finished beer sample was likely contaminated with lactic acid bacteria and wild…

requires oxygen to grow and it is non-motile.It is an intracellular pathogen which means that infects the macrophages of the bodies immune system.And the reason this bacteria is very effective is because of the waxy coat of Mycolic Acid that onvolves the bacteria.Thia makes staining very difficult and as a key virulence factor for the bacteria. Transmission and Symptoms of Tuberculosis: Transmission is through infected droplets in the air.When someone that is sick with Tuberculosis…

Pathology, Microbiology, and Immunology at Vanderbilt University, School of Medicine, gave this seminar on November 9, 2015. He talks about finding therapeutic targets for Staphylococcus aureus. He states that metals are required for infection and that bacteria encode high affinity metal acquisition systems. Heme, which is a cofactor of hemoglobin, is known to be the most abundant iron source in the vertebrate host, and is the main focus of this seminar. The first step in heme metabolism in…
