General Unknowns Bacterium Vitality en Vida Bacteria play a vital role in our daily lives. It is therefore our right to know the importance of being able to distinguish certain strains of bacteria. With the right knowledge we would be able to come up with a cure for a disease. An identity gives way to knowledge, to better understanding and access to information on how an organism works and how we can prevent its worsening effects or isolate its benefits. Scientists have been trying to…

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 invisible to the naked eye, and require laboratory examination. Understanding lab techniques and procedures used for bacterial identification is crucial to the overall…

Louis Pasteur wasn’t Einstein or Leonardo Da Vinci but his contributions to society played a major role in health. He contributed to science, technology, and medicine. Pasteur was one of the most important founders of medicine and microbiology. We can’t help but wonder how much of a change he would’ve made if he still was alive. One of his biggest accomplishments was pasteurization treatment which resolves pathogenic micro-organisms in certain foods and beverages. Pasteur was born in Dole,…

Louis Pasteur was born in Dole, France on December 27th in 1822. He was the son of Jean Pasteur and Jeanne-Etiennette Roqui. His father was a poorly educated tanner, who had high hopes for his son to excel in his education. * Pasteur gave a significant impact to the world of scientific research through his numerous contributions. Earlier in his life, Pasteur worked as a chemist, and dealt with the specific nature of tartaric acid. Tartaric acid is a type of acid that occurs naturally in many…

IV. Pathogenesis of Staphylococcus aureus A. Mode of Pathogenicity Staphylococcus aureus is both a commensal bacterium and a versatile pathogen. It is commensal because it can harmlessly colonize in the nares, axillae, vagina, pharynx, or damaged skin surfaces (Jenkins et al. 2015). Commensal bacteria supports the superficial layer of our body from pathogenic bacteria. For instances, S. aureus produces bacteriocins (toxins created by bacteria) that impedes pathogenic staphylococcal organism…

The title of the lab: Microorganisms and Humans – Infectious Disease Lab Resource The aim of the lab: The aim of the lab was to see if student could detect streptococci causing bacteria in the back of their throats and other objective was to view pathogen causing diseases under the microscope. Activity 1 – Identification of Human Streptococcal Pathogens Materials 1. Glass microscope slides 2. Bunsen burner 3. Inoculating loop 4. Sharpie pen 5. 2 bacitracin discs 6. Sterile saline tubes 7.…

According to text book and handout Microorganisms, are minute living things that individually are usually too small to be seen with unaided eye. Ubiquity means to be present everywhere. Microbiologist believed that microorganisms are everywhere and have tried to prove it. In this experimenting this lab, we had an experiment on ubiquity. This lab wanted to prove the microbiologist that on this planet has microbes everywhere. To understand more about ubiquity experiment, an important terms need to…

I. INTRODUTION The worldwide the bacterial community includes billions of microorganisms. Microbiologist and other scientists are constantly working of identifying species and classifying them by morphological, biochemical and molecular tests. This is valuable to the medical community, as some of these microorganisms are pathogens, but also to other industries such as pharmaceuticals, foods and drinks production, ecological, agriculture and biotechnology as humans have used bacteria for years…

Microorganisms possess many virulence factors which are usually decided by their genetic makeup. Not many virulence determinants of bacteria are expressed phenotypically. Capsule is one such bacterial organelle which displays many functions that include adherence, resistance to immune clearance, protection against environmental factors and many others including the typing of bacteria based on their specific capsular antigen and rapid diagnosis of capsulated bacterial infections using…
