Abstract

AIMS

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.

METHODS & RESULTS: 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.

CONCLUSIONS

The Compactdry SCD system provides results comparable to those obtained by SPC: simple interpretation, ease of use, long-term storage and good sensitivity.

SIGNIFICANCE AND IMPACT OF THE STUDY

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.

摘要

目的

Compactdry SCD是一种新型的定量、即用型且可自行扩散的干培养基片尿液培养系统，将其与传统方法进行比较以评估定量尿液培养的结果。

方法与结果

对25份尿液标本进行Compactdry SCD检测，并将结果与传统培养方法的结果进行比较。Compactdry SCD分析的结果与标准平板计数（SPC）法的结果相关性良好。事实上，其相关性比浸片系统和SPC更强。Compactdry SCD甚至能检测出低菌尿（<103 cfu ml(-1)）和混合菌尿。
