The Dip-Slide: a modified dip-inoculum transport medium for the laboratory diagnosis of infections of the urinary tract

Abstract

The dip-slide, consisting of a glass microscope slide coated with nutrient medium and inoculated by dipping in freshly voided urine, provides a simple measure of the bacterial concentration in fresh urine. This is a useful supplement to the usual microscopy and culture of urine in the diagnosis of urinary tract infections in general practice, when specimens cannot be delivered to a laboratory within several hours of collection, particularly when urine specimens have to travel by post. Dip-slides are also useful as the sole test in screening for symptomless bacteriuria.

A simple quantitative and qualitative microbiological screening test for bacteriuria

“…allows a single medium to be used in contrast to the two media employed in the slide method of Naylor and Guttmann (1967). The reagent has been found not to interfere with the serological specificity or other characteristics of a variety of pathogenic microorganisms (Mackay-Scollay, 1968).…”

“…These demand considerable time in their performance and skill in their interpretation. Relatively simple microbiological tests have been devised by Leigh and Williams (1964), Mackey and Sandys (1965), and by Naylor and Guttmann (1967) but these have disadvantages either of inaccuracy or inconvenience. A need exists for a simple and accurate method of determining significant bacteriuria (Lancet, 1968), not only Received for publication 13 February 1969. to confirm clinical evidence of urinary tract infection but to enable population surveys to be carried out to uncover inapparent or subclinical infections which frequently lead to irreversible renal damage.…”
