Virology Today: Integration of D. I. Ivanovslii’s Ideas into the Methodology of Science In his research on the tobacco mosaic virus D. I. Ivanovskii has introduced a new type of causative agent of an infectious desease and a new form of life. In this way he has layed the basis of a ne field of science, virology. Its structure of knowledge and the logics of development caused formation of new scientific areas that go beyond the scope of natural science. The cognitive model of virology as science has become the prototype of computer virology and has influenced the development of communication theory.

Food product as a source of viral infections The main routes of transmission of viruses that can enter the body through infected food were considered. It has been shown that viruses are resistant to adverse environmental conditions and may be stored for several months in food and environment. Common sources, which can accumulate enteroviruses, Coxsackie B5 virus, hog cholera virus (HCV), African Swine Fever virus (ASFV), FMD virus, poliovirus, rotavirus and echovirus are described.

The epidemiological situation of West Nile fever in Volgograd region West Nile virus for the Volgograd region is the most important arbovirus infection. The observed decrease in the incidence of WNV from 2001 to 2006, in 2008 and 2009 years, reducing the number of severe disease is only indicative of a temporary regression of the epidemic process in the Volgograd region. In the Volgograd region there are prerequisites and precursors complications epidemiology of West Nile fever. The purpose held in the Volgograd region surveillance in West Nile is to provide the information necessary and sufficient for the analysis of the epidemiological situation, as well as to determine the direction of policy and action in public health management decisions.

Molecular detection of baculoviruses of beet webworm from the collection of All-Russian Institute for Plant Protection Two isolates of baculoviruses from beet webworm Loxostege sticticalis (Lepidoptera: Pyraloidea) deposited in the collection of entomopathogenic organisms as a granulovirus (GVLS-85) and a nucleopolyhedrovirus (NPVLS-90) have been subjected to genotyping using degenerate primers L8F2:L8R2 flanking a conservative region of late elongation factor gene lef8. Both isolates, tested independently to avoid sample cross-contamination, were found to belong to a single molecular haplotype. This haplotype is unique, showing maximum sequence similarity of 73% to Pieris rapae granulovirus (Genbank accession number JX968491) and other granuloviruses. No significant similarity to available sequences of nucleopolyhedroviruses have been found.

Detection, identification and quantitation of bocavirus among children with acute respiratory viral infections and gastroenteritises in Moscow Human bocavirus (HBoV)) causes acute respiratory virus infections and gastroenteritises in humans throughout the world. HBoV DNA detection and identification among children with respiratory infections in Moscow during 2005–2010 by means of reverse transcription with subsequent real time PCR with fluorescent probes showed the long-term average frequency 14, 5 ± 0, 7% for 2, 395 nasopharyngeal lavages (variations in a rang from 13, 5% до 17, 0%). One should note seasonal activity of the HBoV circulation during a year with 2 peaks in autumn-winter and early spring. Among infants and toddlers less than 1 year old the HBoV was associated with other respiratory viruses, whereas for children 2–7 years old the bocaviral monoinfection was prevailed. Gastroenteritises were diagnozed in 34, 3 ± 3, 7% clinical cases. The HBoV viral loads in 40, 5% samples were more than 105 genome-equivalents per 1 ml for the first days postinfection, whereas for mixed respiratory infections and for children with the HBoV monoinfection were less 103 genome-equivalents per 1 ml.
