    Summary- A new Robertsonian translocation was found in 7 animals of the Grey Ukrainian breed. The translocated chromosome, analyzed by GTG- and RBG-banding, resulted from the fusion of chromosomes 8 and 23. C-banding suggested that the translocated chromosome has a double heterochromatic block. Synaptonemal complex analysis was performed using electron microscopy. cattle / chromosome / Robertsonian translocation Résumé- Une nouvelle translocation robertsonienne bovine, 8/23. On a découvert une nouvelle translocation robertsonienne chez 7 représentants de la race Ukrainienne grise. Le chromosome fusionné, analysé par une technique de bandes GTG et RBG, est le résultat de la fusion des chromosomes 8 et 2.i. La technique de bande C suggère que le chromosome fusionné possède 2 blocs hétérochromatiques.

    The study provides the results of AIV surveillance in Central Asia region during 2003-2009. We have analyzed. 2604 samples from wild birds. These samples were collected in Kazakhstan. (279), Mongolia (650), and Russia (1675). Isolated viruses from samples collected in Mongolia (13 isolates) and. in Russia (4 isolates) were described. Virological analysis has shown that 6 isolates belong to H3N6 subtype and. 5 isolates belong to H4N6 subtype. Two H1N1 influenza viruses, one H10N7 virus, two H3N8 viruses, and. H13N8 virus, which is new for Central Asia, have been also isolated. Samples were taken from birds of 6 orders, including several species, preferring water and semi-aquatic biotopes, one species, preferring dry plain regions, and one more species which can inhabit both dry and. water biotopes

    During this research huge surveillance study, the role of Gulls as the nature host of influenza A viruses was established. Oral and cloacal samples from Gulls were collected on the territory of the Russian Far East. Fourteen influenza A viruses were isolated

    ECOLOGY AND EVOLUTION OF HIGHLY PATHOGENIC AVIAN INFLUENZA H5N1 IN RUSSIA (2005-2012)

    Russia covering a large part of Eurasia is of special interest for influenza virus ecology and evolution. The importance of this region has been confirmed by the previous outbreaks of HPAI H5N1 among wild birds from 2005 to 2010. Avian influenza virus surveillance is an important task prior the fundamental study and introduction. these data in practice. The article contains detailed comparative virological, molecular, pathogenic characteristics of H5N1 viruses isolated in Russia. Some molecular-epidemiological aspects are discussed. This study demonstrates the need for ongoing surveillance to detect new variants of influenza viruses and. facilitate prevention of outbreaks

    RARE INFLUENZA VIRUS SUBTYPES ISOLATED FROM BIRDS OF THE SOUTH OF WESTERN SIBERIA

    During avian influenza virus (AIV) surveillance in Russia, 2008, H15N4 subtype of the virus was isolated. All the H15 viruses had been previously isolated in Australia in 1979 and 1983. This is the first report about isolation. of AIV H15 subtype elsewhere. Genetic and. antigenic analyses were made. The significant antigenic differences between A/teal/Chany/7119/2008 strain and. reference strain A/shearwater/ Australia/2376/1979 were revealed. The results of this study show the necessity of monitoring for avian influenza viruses, study of pathogen genetic variability, evolution and ecology

    Организация медицинской помощи детям с травмой в результате ДТП на территории Ростовской области

    Objective: to analyze the efficiency of the Rostov Region’s medical care service for children with severe traumatic injuries due to road traffic accidents. Results. It has been established that the service meets the generally accepted stepwise principles and has a multilevel network of hospitals, which allows the earliest performance of the required volume of medical care in relation to the pattern and severity of lesions. It has been shown that 58.3% of the children with severe traumatic lesions are primarily admitted to the central district hospitals and emergency care ones that are aimed at rendering medical aid to the adult population. Thus, medical care is delivered to the above contingent by non-pediatric surgical and resuscitative-anesthetic services. Conclusion. By keeping in mind the specific features of the emergency medical system existing in the region, the authors propose its further development, by organizing interregional centers on the basis of a number of central regional hospitals for the treatment of children with traumatic lesions (among other things, by allocating pediatric beds in the intensive care units). The stepwise solution of this problem is currently being done in the Rostov Region in two main directions: 1) organization by developing a round-the-clock advisory subdivision (with an exiting sanitary aviation team) on the basis of – the regional children’s clinical hospital and 2) methodical maintenance of multidisciplinary h°spitals in delivering medical care to different age-groups children. Key words: road traffic accidents, emergency medical service, children, traumatic lesions.Цель работы — проведение анализа эффективности действующей на территории Ростовской области службы оказания медицинской помощи детям с травматическими повреждениями в результате ДТП. Результаты. Установлено, что служба в целом соответствует общепринятым принципам этапности и имеет многоуровневую сеть стационаров, что позволяет обеспечить выполнение в максимально возможные сроки необходимого объема медицинской помощи в зависимости от профиля и тяжести повреждений. Показано, что 58,3% от общего числа пострадавших — детей, с тяжелыми травматическими повреждениями первично госпитализируются в центральные районные больницы и больницы скорой медицинской помощи, преимущественно ориентированные на оказание медицинской помощи взрослому населению. Таким образом, медицинская помощь указанному контингенту оказывается не педиатрическими хирургическими и реанимационно-анестезиологическими службами. Выводы. Учитывая особенности действующей на территории области системы экстренной медицинской помощи, предложено дальнейшее развитие за счет организации на базе ряда ЦРБ межтерриториальных центров по лечению детей с травматическими повреждениями (в том числе выделение в составе реанимационных отделений педиатрических коек). Этапное решение данной проблемы в настоящее время осуществляется в Ростовской области по двум основным направлениям: организационному — за счет развития круглосуточного консультативного подразделения (с выездной бригадой санавиации) на базе Областной детской клинической больницы и методическому сопровождению работы многопрофильных стационаров области по вопросам оказания медицинской помощи в разновозрастных группах детей. Ключевые слова: дорожно-транспортные происшествия, служба экстренной медицинской помощи, дети, травматические повреждения

    An avian influenza A(H11N1) virus from a wild aquatic bird revealing a unique Eurasian-American genetic reassortment

    Influenza surveillance in different wild bird populations is critical for understanding the persistence, transmission and evolution of these viruses. Avian influenza (AI) surveillance was undertaken in wild migratory and resident birds during the period 2007–2008, in view of the outbreaks of highly pathogenic AI (HPAI) H5N1 in poultry in India since 2006. In this study, we present the whole genome sequence data along with the genetic and virological characterization of an Influenza A(H11N1) virus isolated from wild aquatic bird for the first time from India. The virus was low pathogenicity and phylogenetic analysis revealed that it was distinct from reported H11N1 viruses. The hemagglutinin (HA) gene showed maximum similarity with A/semipalmatedsandpiper/Delaware/2109/2000 (H11N6) and A/shorebird/Delaware/236/2003(H11N9) while the neuraminidase (NA) gene showed maximum similarity with A/duck/Mongolia/540/2001(H1N1). The virus thus possessed an HA gene of the American lineage. The NA and other six genes were of the Eurasian lineage and showed closer relatedness to non-H11 viruses. Such a genetic reassortment is unique and interesting, though the pathways leading to its emergence and its future persistence in the avian reservoir is yet to be fully established
