A 29-year-old female complains of copious vaginal discharge and dysuria. On history, the patient confirms she has had previous sexually transmitted infections and uses an IUD for contraception. Gram stain of her discharge reveals numerous neutrophils and Gram-negative diplococci. You explain to your patient that after completing treatment she will not be protected against future infections from the organism causing this infection. A primary feature of this organism that facilitates evasion of adaptive immunity is:
a. A-B exotoxin production
b. Beta-lactamase production
c. IL-2 supression
d. Pili gene variation
e. Thymidine kinase mutation
