Answer

The P fimbriae family of adhesins is epidemiologically associated with prostatitis, pyelonephritis (70-90% of strains), and sepsis. This family of adhesins is associated with less than 20% of asymptomatic bacteriuria (ABU) strains. The AFA/Dr family is associated with diarrhea, UTI, and particularly pyelonephritis in pregnancy. The S/F1C family is associated with neonatal meningitis and UTI.
