[Localization of urinary-tract infection by demonstrating antibody-coated bacteria in urine (author's transl)].
The immunofluorescence test for demonstrating antibody-coated bacteria as a direct method of localizing urinary-tract infection was performed on 34 patients, results being compared with the Fairley test. Mid-stream urine contained at least 10(5) bacteria/ml in all patients. The direct localization method revealed upper urinary-tract infection (renal bacteriuria) in 18 patients, lower urinary-tract infection (cystitis) in eight. Presence of antibody-coated bacteria correlated well with renal bacteriuria, such antibody having been demonstrated in all of the eighteen patients with renal bacteriuria but in none of the eight with lower urinary-tract infection (cause located in the bladder). The test has proved to be highly sensitive method for differentiating between upper and lower urinary-tract infection.
