Article Synopsis
  • - Since its discovery in Africa, the West Nile virus has spread globally, becoming common in many countries, including Russia, with significant expansion occurring there in 1999.
  • - Research on the virus in Russia has gained importance, leading to a large dataset collected since 2007 to understand its genetic diversity and spread.
  • - A study analyzing 55 complete genome sequences found that the West Nile virus in Russia is genetically diverse, classified into four main groups, with one group spreading rapidly to new areas.

It is difficult to overestimate the urgency of the problem of well-timed diagnosis of viral infections. According to the WHO, dozens of outbreaks of viral diseases are recorded annually, both in developing and developed countries. Moreover, the seasonal flu virus alone is capable of infecting up to 20% of the population, even in European countries with a high level of medicine.

The reagent kit AmpligenBurk-mallei/pseudomallei-RT PCR is designed for detecting in vitro diagnostics and differentiate the DNA of glanders and melioidosis pathogens by real-time multiplex PCR in biological (clinical) material and cultures of microorganisms, as well as environmental objects and solid food products (rice). During clinical testing diagnostic value of reagent kit AmpligenBurk-mallei/pseudomallei-RT PCR has been studied. Based on the results obtained, a high analytical sensitivity (1×10 microbe cells/ml) and specificity (100%) of PCR-RT with the developed reagent kit were established, regardless of the type of material being studied.

The threat of rapid spread of Zika virus beyond endemic regions has given rise to more research in field of epidemiology and clinic, as well as to the search for Zika fiver new diagnostic and preventive tools. Between 2013 and 2017 in Russia 18 cases of infection transmission by travellers were reported. Fever Zika reference monitoring center in Volgograd Research AntiPlague Institute (Volgograd, Russian Federation) provides counseling and methodological assistance on laboratory diagnosis and monitoring of Zika fever.
