...You are given a sputum sample from a patient that may be infected with a bacterium from one of the following genera: Bacillus, Escherichia, or Mycoplasma. In a Microsoft Word document, describe the important anatomical differences among these three genera (i.e., those features that could be used to differentiate among them) and the staining protocols you would use to identify which genera is causing the patient’s infection. When discussing each staining protocol, it is important not only to mention the steps involved, but also how each step and each protocol would identify or eliminate each of these genera as a suspect. You may refer to other scientific resources, but they should be in addition to and not in place of the Module 2 resources. The task given for observation and diagnosis involves a sputum sample given from an infected subject that possibly have illness that is related to three possible microorganisms with their genera being of; Bacillus, Escherichia, or Mycoplasma. Our initial testing must involve the definition of each and by this will help to narrow the field of the type of particular microbe involved. The first is of the genera Bacillus, Gram-positive and rod-shaped bacteria, has two separate meanings, first, a bacterial shape, second, when capitalized and italicized refers to a specific genus, each one form long twisted chains of cells. The second microbe involved is Escherichia, Gram-negative, rod shaped, bacterium that is part of our normal lower GI flora...

...You are given a sputum sample from a patient that may be infected with a bacterium from one of the following genera: Bacillus, Escherichia, or Mycoplasma. In a Microsoft Word document, 1. Describe the important anatomical differences among these three genera (i.e., those unique features that could be used to differentiate among them such as their shape, size, unique things found in each one, etc.). Bacillus is defined as any of a group of rod-shaped, gram-positive, aerobic or (under some conditions) anaerobic bacteria widely found in soil and water and they frequently occur in chains. Escherichia is a genus of Gram-negative, non-spore forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae. In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a portion of the microbially derived vitamin K for their host. While many Escherichia are killer commensals, particular strains of some species are human pathogens and are known as the most common cause of urinary tract infections, significant sources of gastrointestinal disease, ranging from simple diarrhea to dysentery as well as a wide range of other pathogenic states. While E. coli is responsible for the vast majority of Escherichia-related pathogenesis, other members of the genus have also been implicated in human disease. Mycoplasma refers to a genus of bacteria that lack a cell wall. Without a cell wall, they are unaffected...

...In this essay, you are asked to demonstrate your understanding of the different types of culturing and staining procedures discussed in Chapters 3 and 7. You will have TWO WEEKS to research and compose your essay. Consider the following scenario: You are given a sputum sample from a patient that may be infected with bacteria from one of the following genera: 1 Bacillus 2 Escherichia 3 Mycobacteria For this essay, • Describe the handing of the specimen and how the infectious agent, in this case a bacterial pathogen, is isolated from the sputum sample. • Explain techniques used to isolate bacteria from a clinical specimen using the LearnSmart laboratory exercise, “Isolation Methods” as well as Chapter 7 to support your account. • Discuss how staining techniques may be applied in the identification of an unknown sample. • Discuss each staining protocol. Mention the steps involved and how each step and each protocol would identify or eliminate each of these genera as a suspect. You may refer to other scientific resources, but they should be in addition to and not in place of the module resources. • Describe the important anatomical differences among these three genera and the staining protocols you would use to identify which genus is causing the patient’s infection. Your essay should be approximately 2 pages in length, double-spaced in 10-12 point font. Please be sure to cite all sources of information, including the text book, in the essay text and on a reference page...

Bacillus: Rod Shaped Bacteria, plural bacilli, Divide only across their short axis, most appear in single rods. Diplocacilli appear in pairs after divison, and streptobacilli occur in chains. Some bacilli look like straws, others are tapered and look like cigars and some are oval and look similar to cocci so they are called coccobacilli. Genera Bacillus contains bacteria such as Bacillus anthracis the bacteria that causes anthrax. Bacillus cells often form long, twisted chains of cells. Gram POSITIVE, can be aerobic or anaerobic. Prokaryotes, Has a cell wall Mycoplasma: Lack a cell wall Unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. May be parasitic...
