[The estimation of the hepatitis E proportion in the etiological structure of acute viral hepatitis in certain regions of of Kyrgyzstan.].

Despite the fact that the Kyrgyz Republic (KR) belongs to the highly endemic regions of the world for hepatitis E, the true extent of the spread of this infection in the country remains poorly understood. It was estimated the prevalence of serological markers of hepatitis E virus (HEV) infection among patients with acute viral hepatitis (AVH) from the regions of the Kyrgyz Republic with a high level of seroprevalence previously established by us. Blood sera samples of hepatitis patients who were admitted to hospitals of Kyrgyzstan in the period 2018-2019 were examined by the enzyme immunoassay method using the kits «DS-ELISA-Anti-HEVIgG» and «DS-ELISA-ANTI-HEV-IgM» (RPC Diagnostic Systems, Russia).

[The system of epidemiological control of hepatitis E and complex of anti-epidemic, hygienic and veterinary sanitary activities in the Belgorod oblast].

The Hepatitis E (HE) is a viral liver disease that is common on all continents at different rates and very frequently is not symptomatically distinguishable from other viral hepatitis, such as hepatitis A, B and C, as well as from other infectious diseases referred to as "acute jaundice syndrome". The GE-anthroponosis (in the case of infection caused by genotypes 1 or 2 of hepatitis E virus) or anthropozoonosis (in the case of infection caused by 3 or 4 viruses) is predominantly propagated through fecal-oral transmission. The article presents the general characteristics of VGE, human risk factors and means of prevention.

[Experience of application of multiplex qPCR for differential diagnostics of intestinal viral infections].

Aim: Evaluate the effectiveness of multiplex reverse transcription (RT) and polymerase chain reaction with fluorescence detection in real time mode (qPCR) methods for differential detection of 11 groups of intestine viruses (adenoviruses, enteroviruses, polioviruses, hepatitis A and E viruses, group A and C rotaviruses, orthoreoviruses, noroviruses, sapoviruses and astroviruses) in various biological samples.

Materials And Methods: Panels of virus isolates and clinical samples characterized by reference methods were used to evaluate sensitivity of detection of various intestine viruses. Nucleic acids were isolated from study samples and multiplex RT and qPCR were carried out.
