Abstract

In order to find an easily available, simple, reliable and inexpensive method for demonstrating significant bacteriuria in routine urine examination, microscopic observation and bacteriological cultures have been made in parallel on total of 206 urine samples. Microscopic examinations of centrifuged deposit for both pus cells and bacteria were found to be more satisfactory in urine specimens with significant bacteriuria than the examinations for either of these elements alone. The criteria of more than five pus cells per high power field and organisms visible in methylene blue stain had sensitivity of 79% and a false positive rate of 13%.

摘要

为了在常规尿液检查中找到一种易于获得、简单、可靠且廉价的方法来证明显著菌尿，对总共206份尿液样本同时进行了显微镜观察和细菌培养。发现在有显著菌尿的尿液标本中，对离心沉淀物中的脓细胞和细菌进行显微镜检查比单独检查这些成分中的任何一种都更令人满意。每高倍视野超过五个脓细胞且在亚甲蓝染色中可见微生物的标准，敏感性为79%，假阳性率为13%。
