Piliation control mechanisms in Neisseria gonorrhoeae.

S Bergström, K Robbins, J M Koomey, J Swanson.

Abstract

Gonococci (Gc) undergo pilus+ to pilus- "phase transitions" readily in vitro. In the present study we sequenced pilin mRNA from reverting, pilus- Gc by oligonucleotide primer extension and compared these pilin mRNA sequences with those expressed by their pilus+ predecessors and pilus+ revertants. The results suggest that genetic rearrangement within the pilin structural gene can generate defective pilin gene products, resulting in a pilus- phenotype. These pilus- Gc give rise to pilus+ revertants upon reconstitution of their modified pilin gene.
