Question

78 Exercise 7: Selective and Differential Growth Medium and Tests 1 have been identified. These arms are ganima prutenbacteria. Trods and oxidase negative There are also gram+ onanisms among our unknowns. The blochemical changes we aim to assess are most often mediated by bacterial enzymes and others are fermentations. Color and/or texture changes in the media will aid in the identification of the unknown. The bacterium can be different lated on the basis of their metabolic capacity to manifest biochemical changes. You will be given a form to take notes on all of your results and table listing the names of bacteria and the biochemical results that are expected from them. Comparing your results to the results in the table, you will be able to identify your unknown bacterium Dou Questions 1. What is the basis of discase? nos BOE 2. How do we identify unknown bacterium? Hiah obje Ple 3. Explain the importance of the Gramm stain 1. What is the most important, first step in identifying an unknown bacterium? 5. What are Enterobacteriaceae?

Answer 1

1. The basis of disease is a biochemical change in the site of infection or in the blood caused by bacterial enzymes, bacterial metabolic activity and bacterial manifestation as per the passage above
