This article describes the contemporary methods of diagnosing sexually transmitted infections, their advantages and disadvantages, indications for use. The authors describe application of quantitative polymerase chain reaction in diagnosing inflammatory diseases and dysbiotic conditions in men and women. This method, which is currently the “golden standard” in urogenital pathology diagnostics, has undeniable advantages over microbiological methods and qualitative polymerase chain reaction: the preanalytical stage requirements (preservation of quantitative ratios between microorganisms or nucleic acids of microorganisms) are not as strict, the risk of contamination from outside environment and subsequent corruption of the results is significantly smaller, the conditions for all microorganisms, including those impossible and hard to cultivate, are the same sensitivity and specificity-wise, it is possible to sample materials and evaluate microbiota (ratios of microorganisms and their groups) and also possible to collect samples non-invasively, the speed of testing is high.

ABSTRACT MON 87419 was one of the new transgenic corn events developed in US with the trait of herbicide resistance to both dicamba and glyphosate. To monitor unintended release of genetically modified organism in the future, as well as to meet GM-labeling requirements, it is requisite to develop a reliable method for the detection and quantification of MON 87419, an event-specific primer pair was designed to amplify the 3′-junction site between the endogenous genome sequence and the transferred DNA of GM event MON 87419, amplicons of desired size were produced by qualitative polymerase chain reaction (PCR) assay. For the validation of this quantitative method, the mixed samples containing 10%, 1%, and 0.1% MON 87419 ingredient were quantified. The precisions were expressed as relative standard deviations, deviated by 7.87%, 12.94%, and 19.98%, respectively. These results clearly demonstrate that the PCR methods we developed herein can be used for event-specific quantitative testing of the double-herbicide-resistant corn MON 87419.
