Gram Negative Unknown Lab Report Abstract The Unknown Gram Negative bacterium inoculated in a Tryptic Soy broth medium was randomly selected from a group of other unknowns. In order to identify this unknown the seven different types of biochemical tests will be conducted on this unknown bacterium to identify it out of 6 possible bacteria; Escherichia coli(E. coli)‚ Enterobacter aerogenes (E.aerogenes)‚ Klebsiella pneumoniae (K.pneumoniae)‚ Proteus mirabilis(P.miranilis)‚ Pseudomonas aeruginosa(P

Sp2012 (Set all of your margins to ½”) Purpose: The purpose of this lab is to help you become a little familiar with some of the tests that can be typically performed in a clinical or research lab facility. These tests may help in determining a particular pathogen’s growth needs. There are several sections to this lab. Find each section and complete the “Preparing for Class” sections. Preparing for class - Day 1 Read in your lab manual about the following agar mediums: Blood Agar (pg 168)‚ EMB

this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question and how the bacteria function. Materials and Methods Over a two week period‚ eight prepared types of test media were provided to identify the assigned unknown mixed

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus

across the earth for over 3.8 billion years. The name of the micro-organism that I am researching is E coli‚ which is short for Escherichia coli‚ E. coli diverged around 102 million years ago‚ E coli is a common type of bacteria that can get into food‚ like beef and vegetables. E coli is dangerous because it is damaging to the kidneys and other organs responsible for removing toxins from the body. E coli is an emerging cause of food borne illness. An estimated 73‚000 cases of infection and 61 deaths

Abstract: The purpose of this experiment was to isolate two unknown bacteria and perform a series of selective and differential tests to correctly identify each. After the bacteria was isolated a series of differential and selective tests following the dichotomous key attached were used to identify each bacteria

our skills we have learned in the lab to identify two unknown organisms. PROCEDURE I was given unknown #76. I performed the streak plating method with my unknown organisms. To perform this exercise I needed a TSA plate and labeled the bottom of it with my name‚ group number and organism. I also divided the bottom into three sections. After that‚ I sterilized my inoculating loop using the bunsen burner flame. After letting the loop cool‚ I reached into my unknown test tube with my loop and grabbed

Escherichia coli was discovered by German Bacteriologist Theodore von Escherich in 1885(quote). It is commonly known as E. coli and 0157:H7; E. coli found in the human intestinal tract and is found in multiple forms. E. coli is rod shaped and the size of two microns to one micron. Widely known for the deadly stain found in feces and meat. The pathogen is still a major instrumental issue in human health and is easily infectious with contaminated sustenance. E. coli is gram-negative bacilli tested
