10:50 PM possible Pathogen Assignment Two (Related to Chapter 5-7) You now need to discuss a few more things about your pathogen BASED on what we are learning in Chapter 5-7 1 Answer the following questions about your pathogen. (10 points 2. Then read and compare in two sentences three other student posts in the class for a total of 6 points (one point each). One fact that is similar and one fact that is different FOR YOUR PATHOGEN: Give the name again. (spelling counts) Chapter 5. Metabolism Carbohydrate: (Glycolysis, fermentation, Krebs cycle with or without an electron transport chain, Alternative pathways to Glycolysis are all ways bacteria get their energy requirements) 1. Which type of metabolic pathway is preferred for Glucose metabolism 1 2. Does it use Oxygen as a final electron acceptor in an Electron transport chain or make less ATP by using another electron acceptor. (1) Protein and Lipid Metabolism 3. Are there any specific enzymes your pathogen has for identification example catalase, decarboxylase dehydrogenase and any other identifying features that can be linked to your bacteria? (Remember the Enterotube lab 44.) If yes, name them (2) Chapter 6.Growth requirements 4 How does your pathogen obtain the requirements to build its Elements of life, CHONPS 5. Oxygen requirements for your pathogen is it a facultative anaerobe, an obligate aerobic, or an obligate anaerobe or is it a microaerophille? (1) 6. How can your pathogen deals with the toxic effect of Onygen? (1)Gve the name the enzymes discussed in lecture if it has them) 7. Discuss temperature requirements of your pathogen (1) (Basically which class of temperature does it fall into thermophile, mesophile, psychophile Chapter 7: Control of growth 8. Name two methods of control of growth of your pathogen. (2) Be careful to specify if it is a physical method or a chemical method) This is to help you relate lecture content to a real life PATHOGEN. HIT reply and do your answers. Copy questions so easy to read. You will not see others answers until you have posted your assignment. Please remember others are reading your work so spelling and effort counts.

Explanation / Answer

1.Glycolysis is the most preferred pathway for the glucose uptake takes place in both prokaryote and eukaryotes.

2.Depending upon the type of pathogen,as it may be aerobic and anaerobic it use oxygen or other electron acceptor during electron transport chain.Mostly are anaerobic bacteria.

3.Yes ,some pathogen having particular enzyme for the particular substrate .Example -bacteria causing tuberculosis(Mycobacterium sp.)are catalase positive,they can break hydrogen peroxide to water and oxygen.

4.Pathogen can derive their nutrition from host.Their may be symbiotic ,parasitic or pathogenic relationship between the host and pathogen.Some minerals are formed by own pathogen metabolism.

5.Depending on type of pathogen , some are totally dependent on anaerobic mode(Gram positive bacteria,Bacillus strains) and some are living in aerobic medium (Salmonella typhi) and obligate aerobes includes mostly fungus sp.

6.Pathogen deals with toxic effect of oxygen by several means such as presence of enzymes such as catalase,peroxides and mechanism for removal of reactive oxygen species.

7.Normally temperature of 25-35 degree Celsius is the better for pathogen growth and development.Some require very low called psychrophile(Closteridium botulini), very high tem.

8.Physical and chemical agents like heat ,alcohol are used for control the pathogen growth.Alcohol are used for killing many bacterial species.
