AIM Characteristic of West Nile fever (WNF) virus strains circulating in southern Russia. MATERIALS AND METHODS WNF RNA was amplified directly from clinical samples, mosquitoes and bird tissues by PCR, nucleotides were sequenced directly and analyzed comparatively. RESULTS Related but different genovariants of WNF lineage 1a--"Volgograd" and(More)
Haemorrhagic fever with renal syndrome (HFRS) is the most prevalent zoonotic disease in Russia. It is caused by several hantavirus species hosted by small rodents. We describe spatial and temporal patterns of HFRS incidence in the Russian Federation, and the geographic distribution of prevalent hantavirus species: Puumala (PUUV) and Dobrava (DOBV). Partial(More)
The authors studied drug sensitivity, mutations in the katG, in-hA, alpC, rpoB genes, virulence via the cytotoxicity test on THP-1 cells, and the viability and genetic affiliation of 53 clinical M. tuberculosis isolates versus data on the form and dynamics of a process. Sensitive and resistant strains did not significantly differ in viability and(More)
The non-tuberculosis mycobacteria Mycobacterium avium subsp. hominissuis (MAH) are able to cause human mycobacteriosis. In this work, the results of the first comprehensive study of the genome polymorphism of the clinical strains of MAH were reported using the typing scheme by 13 loci MATR-VNTR (TR292, TRX3, TR25, TR47, MATR-1, MATR-4, MATR-5, MATR-6,(More)
AIM Molecular-genetic characteristic of M. tuberculosis strains isolated from operation material of patients with tuberculous spondylitis. MATERIALS AND METHODS 107 strains of M. tuberculosis isolated in 2007 - 2011 from patients with spine tuberculosis were studied by methods of spoligotyping and MIRU-VNTR by 12 and 24 loci. RESULTS Strains of genetic(More)
AIM Characteristics of drug resistance (DR) and population structure of Mycobacterium tuberculosis in Pskov region. MATERIALS AND METHODS In 90 strains of M. tuberculosis drug resistance was studied by culture method and by using "TB-BIOCHIP"; genotyping was determined by spoligotyping method. RESULTS 55 (61.1%) of 90 M.tuberculosis strains had drug(More)
Sera from patients with acute seasonal fevers and apparently healthy individuals living in the Astrakhan Region, Krasnodar Territory, or Rostov Region were examined in two modifications of enzyme immunoassay for detection of IgM and IgG antibodies to Neapolitan and Sicilian pappataci fever viruses. IgM antibodies to Sicilian pappataci fever virus were(More)
One of the central problems of machine learning is considered—the regression restoration problem. A qualitatively new regression decision tree (RDT) is proposed that is based on the concept of a full decision tree (FDT). Earlier, a similar construction of a decision tree (DT) was successfully tested on the problem of classification by precedents, whose(More)
