A medical microbiology lab performs testing on human samples collected from different body sites. The tests are used to detect and identify any microorganisms capable of causing disease. Knowing of unknown microorganism is important on how this microorganism works and how it is structured‚ means knowing how it can affect humans. The purpose of this study was to identify an unknown bacterium by applying all methods that were previously conducted and learned in the medical microbiology laboratory

has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been presented in the tables‚ charts and drawings herein and

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

method employed to evaluate the effectiveness of antiseptic agents against selected test organism. In this method‚ sterile filter paper disk is impregnated with an antiseotic and placed on fresh heavily inoculated agar plate of a test organism. Following incubation‚ the agar plate is looked for a zone of inhibition. The presence of a clear zone of inhibition surrounding the disk is indicative of inhibitory (antimicrobial) activity against the organism. This experiment deal with the evaluation of

Judson Cotterman III 4/6/2012 Section 185-35L Assignment #3 Gram-positive Pathogenic Cocci Discussion My original hypothesis for the individually collected throat culture on Blood Agar Plates‚ that it would show a mixture of alpha‚ beta‚ and gamma hemolysis‚ was based on the results of the class control samples of S. pneumonia‚ S. aureas and S. epidermis. In these controls S. pneumonia shows alpha and beta hemolysis while S. aureas and S. epidermis showed beta and gamma hemolysis respectively.

relevance of study for human interest in varied perplexities and can dictate a human life ’s progress or deterioration; thus the significance to humans is vital (Talaro 6). The discovery of the microscope introduced a new branch of science called microbiology. The microscope‚ a major instrument in this realm of study makes it possible to observe‚ acknowledge‚ and clarify implications of meaning to the study of organisms. In preparing for two basic observations‚ a wet mount and a simple stain‚ living

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Significance: Understand the use of Mannitol salt agar‚ blood agar and MacConkey agar plates which must be used based on the components of the bacteria. The catalase test will be used to understand the difference in facultative anaerobic and groam positive from aero tolerant anaerobes. The coagulase test converts fibrogen to fibrin‚ causing

Used the sterile transfer loop that been flamed to remove the bacteria from the slant agar and placed onto the blood agar used the streak plate technique. The bacteria were streak across from quadrant 1 into quadrant 2 then heat the loop and allowed to cool. Streaked bacteria from quadrant 2 into quadrant 3. When streaked from the quadrant 3 to 4‚ the loop doesn’t need to be flame. After finished
