EXPERIENCE OF USING A NEW CHROMOGENIC NUTRIENT MEDIUM AND PROSPECTS FOR ITS IMPLEMENTATION IN MICROBIOLOGICAL LABORATORY PRACTICE

Abstract

Over the past years, there has been an increase in diseases caused by opportunistic microorganisms (OCP) all over the world. To identify them, various differential diagnostic nutrient media and microtest systems are used, the disadvantages of which are the duration of the study and significant material costs. The use of chromogenic nutrient media abroad since the second half of the last century has made it possible to solve this problem based on the identification of highly specific bacterial enzymes, which ensured the identification of the pathogen simultaneously with its isolation. The aim of the work was to assess the diagnostic efficiency of a new chromogenic nutrient medium for one-stage isolation and identification of UPM and the prospects for its introduction into microbiological laboratory practice. Research results. In the course of clinical trials of the new medium, it was determined that it is not inferior to the imported chromogenic nutrient medium HiCrome ™ UTI Agar / Modified (India) and is certainly superior in differentiating properties to the domestic commercial medium Endo. The developed environment is protected by a patent of the Russian Federation and awarded the Gold Medal of the European Competition of Inventions in Strasbourg.
