urinary tract infections, rapid methods, nutritive medium, laboratory diagnosis


The paper represents a cycle of scientific-applicative researches on development and improvement of diagnosis methods, cultivation medium and microreagents for rapid diagnosis of the urinary tract infections.

Experimentally, in laboratory conditions, there were determined a selective acceleration factors for rapid growth and multiplication of ethiologic agents in the urinary tract infections, on the basis of which there were developed and improved the following:

As a rezult, there was developed a scheme for rapid diagnosis of urinary tract infections, which permit the cultivation, indication and determination of susceptibility of the ethiological agents of the UTI till 24 hours (from the moment of collection and insemination of the pathological material).

There were carried out 340 specimen, from them 217 (63,8%) – positive. In 203 (93,6%) cases there was observed one isolated, but in 14 (6,4%) cases – 2 isolated. From the positive results in 164 (75,6%) cases enterobacterial microorganisms there were isolated; 38 (17,5%) cases – staphylococci; 12 (5,5%) cases – bacteria P.aeruginosa and 3 (1,4%) cases – levuriform fungus from Candida spp.

The developed methods and microreagents are rapid, economical, sensible, specific and simple in using. They are accesible in microbiological laboratories of all levels in the curative-prophylactic network of public health services.
