A screening method for the rapid detection of bacteriuria through a combination of filtration and staining has been evaluated. 307 urine samples have been tested with both the regular colony enumeration on culture media and the rapid method. Taking 10(5) CFU/ml as a cut-off, the agreement was reached for 279 (90.9%) samples, 65 (21.2%) of which positive and 214 (69.7%) negative. Only 4 (1.3%) false negative and 24 (7.8%) false positive were obtained; false positive (whose real significance is further discussed) anyhow can be corrected after cultural confirmation. If the cut-off is lowered to 10(4) CFU/ml the frequency of agreements is slightly less (88.6%). From the operational side, the method is unsensitive to the antimicrobial content of the urines, and appears easy to apply and quite rapid: a sample needs not longer than 2 minutes to be processed.

D001437	Bacteriuria	The presence of bacteria in the urine which is normally bacteria-free. These bacteria are from the URINARY TRACT and are not contaminants of the surrounding tissues. Bacteriuria can be symptomatic or asymptomatic. Significant bacteriuria is an indicator of urinary tract infection.	Bacteriurias
