Microbiology

Microbiology begins with Robert Hooke in his discovery of a very important part of biology in the year of 1665. He observe while looking through a microscope that life existence of small structural units referred to by Hooke as "little boxes". Hooke constructed his own version of a compound microscope which had two lenses instead of one. He viewed individual cell like structures through the lens marking the beginning to "Cell Theory”. Hooke microscope lacked the capability of resolution and it wasn't

Introduction to Microbiology – Case Study 1 Kristen Alejos You are working as an emergency room nurse in Topeka when a mother brings in her 8 year old son because of severe, bloody diarrhea. When questioned, the boy said that it hurts when he goes to the bathroom and his mother said he had vomited in the previous two days. When asked about their previous movements, the mother and son both mentioned a backyard barbeque that had taken place 6 days earlier. The boy complained that his mother

The purpose of this laboratory exercise was to perform tests necessary to be able to distinguish one microorganism from 10 others. Using a series of biochemical tests and characteristics, unknown #22 was concluded to be Pseudomonas aeruginosa. A dichotomous key was mapped out and used during this process. Using this provided guidance as well as organization as to what the result may be. Upon obtaining the unknown organism, it was important to make a streak plate of the bacteria on TSA. The purpose

Microbiology Unknown Report On June 25th, 2015 I chose the test tube labeled #19. This test tube contained an unknown bacterium, and the purpose was to determine the unknown bacterium by the end of the semester. Throughout the course, I ran a series of differential tests that would lead me to discovering the characteristics of my unknown. These tests that I will discuss in this paper are vital to understanding the biochemical mechanisms that different bacteria can perform, therefore helping me identify

Melissa Babajko Microbiology 214BA Dr. May June 6, 2012 Staphylococcus aureus- Is a facultative anaerobic, Gram-positive, salt positive, cocci shaped bacterium. Staphylococcus aureus is found as normal part of the skin floral in the nasal passages and on the skin. An estimated twenty percent of people naturally have harmless Staphylococcus aureus on their skin and are long-term carries for Staphylococcus aureus. Staphylococcus aureus is the most common strand of Staphylococcus in humans to date

Microbiology is a study of small living organisms that are hard to be seen without using the microscope; such as bacteria, archaea, viruses, and protozoa. Fungi are different, a majority are big enough for us to see. They’re all have a long history of living on Earth, the scientist also believes they are the first living things that are existing way before mammals or human. Those microorganisms are everywhere around us, some are harmless and some can cause serious diseases. The condition and environment

Various test performed to identify two bacterium that were unknown, one was plaque that were scrapped from the teeth and the second was an unknown given. It resulted that the unknown bacterium is Staphylococcus epidermidis. Staphylococcus epidermidis has three drug resistance, and no secondary metabolites. The plaque scrapped from the teeth had a morphology of bacilli and is gram positive. Staphylococcus is gram positive, it is catalase positive and oxidase negative. The minimal inhibition concentration

Abstract Dairy food staff such as soft cheese,cream cheese,raw milk,sour cream,yoghurt and probiotic yoghurt products can be a rich source of diverse lactic acid bacteria.The objective of this lab practical was to isolate lactic acid bacteria(LAB) form raw milk,establishment of pure cultures of LAB,identify LAB and phage recovery and enumeration of recoverd phage.Raw milk was chosen as a sample so as to have a more positive result.To identify bacteria Lab isolated from raw milk,biochemical,morphological

Collection, Observation, and Analysis of Microorganisms in the human environment Introduction The necessity and value of collecting, identifying, and analyzing the various microbes regularly encountered in the daily human environment becomes quite apparent when one gains even

Problem The objective of a lab notebook in Micro 310L: Medical Microbiology Lab is to “record your laboratory activities in such a manner that a second, equally technically proficient person could do the same thing without the aid of outside materials and produce the same results…” (Lemper, n.d.). In order to write a notebook to accomplish this goal, multiple resources are available to students to assist them in writing their notebook specifically a notebook packet the instructor created to help
