DISSOCIATED PILI, THEIR PRODUCTION AND USE

摘要

A method of producing pili and vaccines containing pili is described using bacteria harboring mutations that facilitate detachment of pili from the bacteria. Wild type pili have known immunoprotective effects in treating urinary tract infections. The mutant pili produced by this method are also shown to have such immunoprotective effects. Therefore, the pili may be used to make vaccines for treating urinary tract infections.
