Abstract

Urine was cultured from 441 healthy children, aged 3 to 36 months, simultaneously by standard pour plating and by dip-slide. Significant bacteriuria (greater than or equal to 10(5) colony-forming units/ml in two successive specimens) was found in 13 children (2.9%): 11 boys, 2 girls. Proteus mirabilis was the most frequently isolated organism. Of the 13 infants, 2 had malformations on intravenous pyelography. All 13 had a negative antibody-coated bacteria test. Nitrite test (N-Multistix) and microscopic examination were also performed. The results suggest that asymptomatic bacteriuria cannot be accurately predicted either by microscopic examination or by the nitrite test, and that the quantitative urine culture by dip-slide is the easiest and most reliable way of diagnosing urinary tract infections. However the criteria of Kass were found to be too strict.

摘要

对441名3至36个月大的健康儿童同时采用标准倾注平板法和浸片法进行尿液培养。在13名儿童（2.9%）中发现显著菌尿（连续两份标本中菌落形成单位≥10⁵/ml）：11名男孩，2名女孩。奇异变形杆菌是最常分离出的微生物。在这13名婴儿中，2名静脉肾盂造影有畸形。所有13名婴儿的抗体包被细菌试验均为阴性。还进行了亚硝酸盐试验（N-Multistix）和显微镜检查。结果表明，显微镜检查或亚硝酸盐试验均不能准确预测无症状菌尿，浸片法进行定量尿培养是诊断尿路感染最简单、最可靠的方法。然而，发现卡斯的标准过于严格。
