    Abstract:
    ABACTO-SCREEN is an automated turbidimetric system for rapid screening of bacteriuria composed by a multichannel photometric instrument and an original disposable. In this study the system has shown good sensitivity (6.9% of false negative results on the true positives) and specificity (22.4% of false positive results on the true negatives) when on assuming 100,000 colony forming units (CFU)/ml as a threshold of positivity. Comparison with Abbott MS-2 has revealed better performances for sensitivity and comparable specificity. False negatives analysis has revealed probable influence of anaerobic bacteria in the plate counting or slowing in culture broth growth cause by antimicrobial substances in urine samples.
