Reversion of Neisseriagonorrhoeae from a fimbriated (fim 1) to a non-fimbriated (fim 2) state would result in which one of the following phenomena? 
Select and explain. 
A. Inability of N. gonorrhoeae to colonize the mucosal epithelium, B. Reversion to a Gram-positive stain, C. Death of the organism, D. Loss of serologic specificity
A: Inability of N. gonorrhoeae to colonize the mucosal epithelium
Answer: A: Inability of N. gonorrhoeae to colonize the mucosal epithelium 
Explanation: Bacteria may shift rapidly between the fimbriated (fim +) and the non-fimbriated (fim -) states. Fimbriae function as adhesions to specific surfaces and consequently play a major role in pathogenesis. Lack of fimbriae prevents colonization of the mucosal surface by the bacterium.
