Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

Rebekah Worley February 21‚ 2012 Mitchell Section 4 Biol 311 Staining and Identifying Unknown Bacteria Introduction: The microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of

Tanti Lim Thurs AM Unknown Project I. Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us. 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 . The identification of unknown bacteria is a time honored part of microbiology courses. It will challenge

In the unknown identification labs‚ we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant‚ the P. aeruginosa colonies had a filiform appearance on the edges. I think we correctly identified our unknown as P. aeruginosa because we performed several different tests‚ eleven

Gbengon‚Sennie Microbiology Lab Case study # 5 November 1‚2012 1. What evidence suggests that the young graduate student has contracted what disease? Ans: The signs and symptoms the young graduate student presented‚ show evidence of Lyme disease. 2. What is the environmental pathway for the vector of this disease? Ans: The environmental pathway for the vector of this disease would be a forested habitat. The black-legged tick or the deer tick is the principle vector of this disease (Lyme

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

symbiotic relationship with its host‚ and for this reason it rarely causes diseases and is usually considered nonpathogenic (Avdic‚ Habes‚ and Avdic 3885). Recently though‚ the microorganism is becoming the common cause of nosocomial infections. In “Microbiology: with diseases by taxonomy”‚ Richard Bauman defines a nosocomial infection as “a disease acquired in a healthcare setting.” These infections are often found with implants and plastic items that have inserted into the body‚ such as catheters‚ pacemakers

Determining an Unknown Through Deferential Stains and Biochemical Tests Introduction There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification
