The recent study performed by Rumans and Vosti conveys extremely valuable information and underscores the limitations of the ACB immunofluorescent test to define the site of a urinary tract infection. By accepting the infallibility of the ACB immunofluorescent test, we "fell into the very trap" we were advising others to avoid. Our communication would have been more accurate if we had stated that the consistently negative immunofluorescent test suggested a bladder rather than a renal focus of infection.In addition, as we reviewed our article, we realized that we had inadvertently omitted nitrofurantoin from the list of antimicrobials that have been safely administered to the pregnant woman harboring a urinary tract infection.1
