Question 3

In the context of bacterial pathogenesis, what is the primary mechanism by which lipopolysaccharide (LPS), an endotoxin found in the outer membrane of Gram-negative bacteria, contributes to disease severity?

Question 4

Which of the following best describes the concept of antigenic drift in influenza viruses and its public health implication?
