Immunology Virtual Lab II The branch of biomedicine concerned with the structure and function of the immune system, innate and acquired immunity, the bodily distinction of self from no self, and laboratory techniques involving the interaction of antigens with specific antibodies.
The organisms making up domain Bacteria and domain Archaea are all prokaryotes.
This virtual lab is an introductory course for undergraduate students and deals with the storage and retrieval of data from different biological databases like Gene, Pubmed, GEO, TAIR, Prosite etc. Bioinformatics Virtual Lab II This virtual laboratory is for undergraduate and postgraduate students to get a deeper understanding on the analysis of sequence data, its alignment and the evolutionary relationship.
We first marked the spot on the slide where the sample will be placed. Next the TSIA test was performed. These techniques included sterilizing the loop on the Bunsen burner between inoculations and flaming the opening of the test tube before inserting in the loop with the bacteria.
We gram stained three of the colonies and found that they were all gram-positive bacteria. The domain bacteria is very diverse, making it impossible to identify it without the use of staining and biochemical tests.
You will need to research this. B Next we used a bacterial inoculating loop to spread the inoculating material over the agar to produce isolated colonies.
For the TSIA, the butt and slant were inspected for color change. Gram staining is a differential staining method which results in the classification of two groups of bacteria, Gram-positive and Gram-negative.
Three drops of Methyl Red were added to the MR test tube. This field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry.
Temperature is one of those environmental parameters that limit the growth of species, including bacteria Harley and Prescott Microbiology Virtual Lab I The study of microorganisms, which are unicellular or cell-cluster microscopic organisms.
Three treatments were performed: Second, I also know that the bacteria that grow in polar habitats are different than those that grow in temperate climates NSF Some of the results had similar characteristics to other gram-negative bacterium.Lab, Week # 5.
BIOTECHNOLOGY. Introduction. In this Experiment we will learn how to identify the unknown bacterium according to the case study given as you start to perform your procedures and following the steps. We performed a two-part experiment to gain a better understanding of bacteria through gram-staining.
Gram staining is a differential staining method which results in the classification of two groups of bacteria, Gram-positive and Gram-negative. discussion/conclusion After several different biochemical tests, it was concluded that the Gram positive in unknown was Staphylococcus aureus.
The bacterium was grown on a TSA agar plate for use of additional tests, gram stain reaction determined that the unknown was a gram positive cocci. Bacterial Classification and Identification Kunle Kassim, PhD, MPH Professor, Microbiology August, URGENT!!!!
•It is important for you to review the powerpoint lectures on Bacterial Cell Structure and Bacterial Metabolism from CELL WALL OF ACID-FAST BACTERIA. UNKNOWN LAB REPORT. Unknown Number Tyler Wolfangel. April 29, BIO Introduction. The study of microbiology requires not only an academic understanding of the microscopic world but also a practical understanding of lab techniques and procedures used to identify, control, and manipulate microorganisms.
Staining and Interpretation of Smears [Preparing a smear] [Gram stain procedure and examination] [Negative staining] [Spore staining [Observation of living bacteria] Important information such as shape and degree of motility can be obtained by observation of living bacteria with the phase contrast or dark field microscope.Download
