Answer

Bacterial strains that produce ABU may in some instances provide a measure of protection against symptomatic infections from UPEC and other organisms. On the other hand, ABU may also cause increased morbidity and mortality. Once bacteriuria is established, these strains appear to stop producing adhesins, allowing them to survive and persist without producing an inflammatory reaction.
