A patient is infected by a pathogen. Explain the process of the imitation of the immune response (5 marks) The paitent was prescribed antibiotics yet their symptoms did not improve. What can you infer from this? (1 mark)?

5 of the following...
Pathogen has antigens on its surface that are recognised as foreign by the immune system
T helper cells stimulate cytotoxic T cells, B cells and phagocytes (or lysosomes)
B cells produce antibodies complementary to the antigen
Antigen presenting cells present antigens from the pathogen on their surface.
T cytotoxic cells kill/destroy antigen presenting cells displaying the antigen-antibody complex.
Antigen-antibody complex leads to the destruction of the pathogen (not antigen)
Via agglutination and 
Phagocytosis of pathogen from lysozymes.
Memory cells are produced for a future secondary immune response.
//////
That the pathogen was a virus and not a bacteria.
