Abstract and Introduction Microorganism identification plays a very critical role in the medical significance of modern medicine. One example of reasoning behind it can be for the detection of a disease causing organism in a patient, so it can be certain that it will be appropriately treated. Numerous species of bacteria can appear to share identical morphology (spirilli, cocci, rods), when looking through a microscope. There are many methods and biochemical tests that can be performed to differentiate
For many years the identification of microorganisms has been important in the world of medicine. It is essential or correct disease diagnosis in patients and for proper treatment. Knowing the correct identity and characteristics of microorganism is crucial when disease outbreaks occur in populations, also knowing how humans can benefit from microorganisms is important; many can be used in making certain foods or antibiotics. The purpose of this study project was to carefully isolate and identify
Identifying Two Unknown Species of Bacteria Materials and Methods Week 1, Day 1 (10 November 2000) The first day an unknown sample was assigned to each group of students. The first test applied was a gram stain to test for gram positive or gram-negative bacteria. The morphology of the two types of bacteria was viewed under the microscope and recorded. Then the sample was put on agar plates using the quadrant streak method for isolation. There were three agar plates; one was incubated
MCB 3020L- Section 018 Unknown #16 Abstract This report contains the background information on gram positive and gram negative bacteria, which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of identification used are also described
test was also negative. The Novobiocin test was sensitive with a forty millimeter zone of inhibition. The effects of oxygen on my unknown bacterium was facultative anaerobic meaning the the bacteria was distributed throughout the tube but mainly in top of the tube . In the catalase test it came out positive so there was some bubbling. Introduction In the unknown lab we had to find out what bacterium we had through a series of tests that we had previously done as a class. The
specimen was an unknown sample of a mixed culture of two different species of bacteria. The first step that was taken was obtaining a pure culture of each species of bacteria by isolating one species from the other. Once isolation was complete, the isolated cultures were tested using procedures and tests that had been performed during previous lab sessions. Each mixed culture that was tested had one gram positive and one gram negative bacterial species. The possible species of bacteria that could have
Laboratory Report: Isolating & Identifying Bacteria Introduction: Through the conduction of numerous experiments, the identity of two bacterial isolates was determined. The tested specimen was an unknown sample of a mixed culture of two different species of bacteria. The first step that was taken was obtaining a pure culture of each species of bacteria by isolating one species from the other. Once isolation was complete, the isolated cultures were tested using procedures that had been performed during
140 Matthew Tuthill Unknown Lab Report 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 I have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium. The purpose
Identifying Unknown Bacteria: Streptococcus agalactiae Introduction: This experiment was conducted to find the genus and species of an unknown bacteria prescribed by the lab teacher, which was unknown bacteria GA3 in my case. Identification of unknown bacteria techniques are used on an every day basis to figure out what type of bacteria it is and to find the best method of how to treat a patient with this bacteria (1). All five “I’s” of Microbiology were used in the testing for the unknown culture.
The purpose of this experiment was to identify two species of bacteria from an unknown mixed sample out of a possible twelve strains. With the intentions to correctly identify the unknown bacterium, a plethora of test were executed and documented, yielding the appropriate results for that particular sample. In this experiment, many methods were critical in the identification of the unknown. A dichotomous key, streaking and staining techniques, microscopy, differential and selective media, colony
