Describe how stopping complement activation would protect the bacteria?
Homework Answers
As complement system acts by degradation of the foreign body with the help of enzymes such as proteases , lysozyme and also activate macrophages to degrade the remain debries which shows us that complement play a important part for immunity in our body but if complement system is not activated then the bacterial cell degradation and lysis would not occur and it will stay protected . Presence of capsule in bacteria makes the complement system activation to stop as it hides the antigens of bacteria and that is how bacteria is protected .

3. What are two ways by which bacteria can overcome (or resist) the effects of antibiotics (i.e., what are 2 things bacteria can do to antibiotics so they do NOT work against bactertia)? Which form of DNA is most likely to contain genes that specify antibiotic resistance? 4. Some bacteria can stop the activation of complement. Suggest how this might be accomplished (ie- suggest 2 or 3 things bacteria might do to complement to stop or prevent complement activation). Describe...

Question 18 4 pts What role do restriction enzymes play in bacteria? How do bacteria protect their own DNA from the action of restriction enzymes? Change the surface proteins of bacteria; since DNA is not protein, there is no need for protection Cut foreign DNA into pieces; bacteria have RNA genomes. Destroy invading viral DNA: bacterial DNA does not contain the restriction enzyme recognition sequences. Restrict the growth rate of bacteria; bacterial DNA is restriction enzyme resistant. Question 18 4...

In order to begin the complement activation cascade in response to an antigen like LPS from bacteria, the following is needed (assume LPS does NOT contain repeating epitopes but instead has a specific epitope): Select one: O a. The CCR5 receptor, on the epithelial cell, which will bind to the T cell receptor complex on the T cell O b. The T cell receptor complex on the T cell, which will bind to the B cell receptor on the B...
