In Reply We thank Britton and Antoon and Steiner for their comments that gave us the opportunity to clarify a number of points on our work. First, we confirm that bacterial meningitis, bacteremia, and urinary tract infection were mutually exclusive and that of the 8 cases of bacterial meningitis, 2 had associated bacteremia (both with the same organism as in the cerebrospinal fluid) and 2 had a urinary tract infection (1 with the same organism as in the cerebrospinal fluid and 1 with a different organism). Of the 13 cases of bacteremia, 8 had also a urinary tract infection.
