Comparison of a new system (Compactdry SCD) with conventional methods for quantitative urine cultures.

Abstract

Compactdry SCD, a new quantitative, ready-to-use and self-diffusible dry medium sheet urine culture system, was compared with conventional methods to evaluate the results of quantitative urine cultures. Compactdry SCD was tested on 25 urine specimens, and results compared with those of traditional culture methods. The results from Compactdry SCD analysis correlated well with those from the standard plate count (SPC) method. In fact, the correlation was stronger than that dipslide systems and SPC. Even low-count bacteriuria (< 103 cfu ml(-1) and mixed bacteriuria were detected by Compactdry SCD. The Compactdry SCD system provides results comparable to those obtained by SPC: simple interpretation, ease of use, long-term storage and good sensitivity. This is the first report suggesting that the Compactdry SCD system has many advantages over traditional quantitative urine culture methods and that it is both appropriate and practical for clinical use.
