Bacterial identification is crucial to the healthcare setting in that it helps prevent or reduce disease. Multiple tests were conducted in attempt to identify the unknown microorganism that was swabbed from a cheek, and their materials, methods and results were described. The goal of the unknown lab experiment was achieved by identifying the genus and possible species through interpretation of the results found. Microbiology is the study of microscopic organisms. These organisms are virtually…

rod shaped bacteria. Botulism was discovered by Émile van Ermengem in 1897 after a contaminated piece of ham poisoned thirty people. He was the first to isolate the bacteria, and determined that C. botulinum was capable of producing heat-resistant endospores. He is also credited with discovering the deadly toxin C. botulinum produces. Botulism is the disease that arises from toxins produced by C. botulinum. Botulism can arise from contaminated canned goods. The characteristic bulging on the…

exact temperature and the duration of heating is not known, it appears that Hankin might have used a considerable temperature for a long duration that would have killed all biological substances, including bacteriophages, except perhaps bacterial endospores (Abedon et al, 2011).…

Streptococcus includes: gram staining, mobility tests, oxidative-fermentative tests and endospore tests. The other tests that help identify the species include: capsule tests, catalase tests, hemolysis tests and pyrrolidonearylamidase tests. (2). The genus Streptococcus is a, gram-positive cocci which ferments sugar, but the final product will always be lactic acid (2). Streptococcus also occurs in pairs or chains, has no endospores and is not motile (1). Although all of the members of the genus…

This led staphylococcus to be the only one that was not eliminated up to this point. When I learned that my chosen bacteria did not produce endospores I began to truly believe my unknown bacteria was Staphylococcus epidermidis. Unfortunately, I was unable to participate with the CNA and MSA experiment. This would have helped greatly in ensuring that I truly had chosen the right bacteria. CNA would…

Reproduction of Archaebacteria Archaeal bacteria do not have a nucleus, so it can not go through mitosis. In a means to reproduce, they procreate using binary fission. During the process multiple fission, the replication of the archaeal DNA occurs and the two strands are pulled apart. Archaeal chromosomes replicate using DNA polymerases that mirror complements eukaryotic enzymes. Protein FtsZ, the protein that directs cell division, forms a contracting ring around the cell. The factors of the…

The two types of bacteria are archaebacteria and eubacteria. What characteristics distinguish these two groups from the other kingdoms? These two groups are different from other kingdoms because all cells in these kingdoms are single-celled organisms whose organelles are not membrane bounds. They are also microscopically small. What is the average size of a bacterium? An average bacterium is about 1-2 micrometres long. How many prokaryote species have been discovered? How many are estimated to…

brain. The experiments used for identification of bacteria samples were efficient and extremely useful. If the study were to be repeated, certain tests that were non successful in lab such as the oxygen tolerance tests and the test for capsules and endospores. Had these tests been completed successfully with in the first trial of the study their results would have aided in a more time efficient identification of the genus of bacteria present with in the soil sample. Although these results would…

Introduction: The effectiveness of Antimicrobial agents against Microorganisms Population of microorganisms or growth are killed and/or inhibited by natural or synthetic chemical antimicrobial controls (Madigan, et al 2012). Antimicrobial agents are grouped according to their efficacy against microorganisms. Bactericidal that kill and bacteriostatic prevent and/or reduce growth (Madigan et al, 2012). Harmful pathogens are targeted with different antimicrobial agents according to their toxicity…

anthracis is an endospore-forming, facultatively anaerobic, bacterium that normally dwells in soil, vegetation and mainly livestock that are herbivores (Micro book). Although B. anthracis causes one disease, there is three manifestations or transmission of this bacterium…
