Quantitative Urine Cultures

Simple disposable method for quantitative cultures of urine.

A disposable kit was tested as a means of detecting significant bacteriuria by quantitative culture of urine. The total error in 3,563 specimens tested by five investigators was less than 1%. The method was very effective in differentiating significant bacteriuria, i.e., more than 100,000 bacteria per ml of urine from uninfected urine. In specimens from patients with urinary tract abnormalities...

Urine screening: an alternative to urine cultures.

Urine cultures represent one of the most commonly submitted specimens to a microbiology laboratory. In an attempt to manage effectively this type of specimen, Bac-T-Screen (BTS), nitrate and leukoestrase test were performed on all clean catch urine specimens sent for culture. Three hundred and four specimens were screened by these methods. The BTS, by itself, had the highest sensitivity, and sp...

Quantitative urine cultures do not reliably detect renal candidiasis in rabbits.

The significance of quantitative urine cultures in patients at risk for hematogenous disseminated candidiasis is controversial. While various concentrations of Candida spp. in urine have been suggested as critical cutoff points in the diagnosis of renal candidiasis, other investigators consider quantitative cultures less critical in diagnosing upper tract infections. To determine the significan...

Cultures in Diagnosis of Melioidosis Role and Significance of Quantitative Urine

Role and significance of quantitative urine cultures in diagnosis of melioidosis.

Melioidosis is associated with significant mortality in countries in which it is endemic. Previous studies have demonstrated that quantitative Burkholderia pseudomallei counts in blood are predictive of mortality. Here we examine the relationship between outcomes and quantitative B. pseudomallei counts in urine. A total of 755 patients presenting to Sappasithiprasong Hospital, Ubon Ratchathani,...
