Findings of <i>Amblyomma americanum</i> L., 1758 in the Territory of Eastern Siberia (Russia)
In June, 2008, in the Irkutsk suburban zone, a man was beaten by a tick of an unknown in this area species. According to its morphological characteristics this tick was classified as Amblyomma americanum L., 1758 species, which is the endemic one in the North, Central, and South America. In this respect, the discovery of the unknown previously in this region and in the Russian Federation species of the ixodic tick is not only of a great scientific importance, but presents specific practical interest, as the ticks of this species are the carriers of a wide range of infectious diseases. Probable scenarios of importation of the new species of ticks in the territory of the Russian Federation are under discussion now and the risks, related to this problem, are being assessed
CIRCULATION OF ARBOVIRUSES AND INFLUENZA VIRUS IN PRIBAIKALYE
The California encephalitis serogroup virus, Batai virus and Geta virus were isolated as result of investigation of distribution of arboviruses in Pribaikalye. The results of the study of influenza A virus in birds in Pribaikalye are presented as well
Innovation Contests with Entry Auction
We consider procurement of an innovation from heterogeneous sellers. Innovations are random but depend on unobservable effort and private information. We compare two procurement mechanisms where potential sellers first bid in an auction for admission to an innovation contest. After the contest, an innovation is procured employing either a fixed prize or a first-price auction. We characterize Bayesian Nash equilibria such that both mechanisms are payoff-equivalent and induce the same efforts and innovations. In these equilibria, signaling in the entry auction does not occur since contestants play a simple strategy that does not depend on rivals' private information
THE PREVALENCE OF TICK-BORNE ENCEPHALITIS VIRUS ANTIGEN IN SERUM SAMPLES FROM PEOPLE SUFFERED FROM TICK BITES
The information about more than 17 thousand cases of public inquiries to the Center of Diagnostics and prevention of tick-borne infections of Scientific Center of Problems Family and Human Reproduction Problems because of bites of ticks at the territory of Irkutsk Region during the last six years (2007-2012) is analyzed in the article. All age groups undergo to the bites of ticks. Over the half of the people asking for help have the policy of voluntary health insurance of "Anti tick" kind. The percentage of people vaccinated against the tick borne encephalitis is a little bit over than 8 % what proves the low level of the sanitary education and neglect to the human health in the region. Every year the cases of tick's bites and findings of tick-borne encephalitis virus antigen in blood serum of bitten people in the northern areas of Irkutsk region are revealed. Every year in average 90 examples of blood serum had tick-borne encephalitis virus antigen that means 3 % of bitten people have pre-clinical infection of tick-borne encephalitis. Patients with positive result of tick-borne encephalitis virus antigen (543 patients) had the necessary consultation and preventive treatment with specific immunoglobulin according to the instruction of application. Diseases of tick-borne encephalitis among the patients had the preventive treatment in time were not marked
THE SPREAD OF THE TICK-BOORNE INFECTIONS IN THE BASIN OF SELENGA RIVER IN BURYATIA AND MONGOLIA
The results of the research of Selenga river basin as territory of highest risk of human infection with diseases with natural focality in Buryatia and Mongolia are present in this paper. Both in Buryatia and. in Mongolia the highest incidence rate for tick-borne encephalitis is associated with districts situated in the basin of Selenga river - Pribaykalskyi district and Selenge aimag respectively. All tick-borne infections and. every vector tick species detected in Buryatia and. Mongolia so far are present on the territories of these two districts. The epidemiological processes in the natural foci of these territories are shown to be very similar in spite of national and administrative borders
TO HANTAVIRUS INFECTION IN PEOPLE AND SMALL MAMMALS IN BAIKAL AREA
The article describes the results of recognaissance surveys of blood serums of humans in Baikal area for hantavirus antibodies and of tissue specimens (lungs) of small mammal for hantavirus antigens. This investigation demonstrated that Baikal area inhabitants contact such dangerous pathogens as hantaviruses. It's proved by the presence of hantavirus antibodies in human serum samples. IgG or IgM antibodies to hantaviruses were found in 3,7 % of 379 tested serum samples. IgM were found in 1,6 % of cases, IgG - in 2,1 % of cases. 2 patients with IgG and IgM with suspected traces of hantavirus infection had complaints to hyperthermia (up to 40,5 °C) and wasting. Blood serums with positive results of hantavirus antibodies were found in residents of Irkutsk region. Hantavirus antigens weren't found in researched lung samples of mouse-like rodent and insectivores from Angarsk, Irkutsk, Zalari and Ust-Kut districts of Irkutsk region and Tunkinsky district of Republic of Buryatia
THE EFFICACY OF PROPHYLAXIS OF LYME DISEASE USING ANTIBIOTICS AMONG PEOPLE BITTEN BY IXODID TICKS
For the first time the results of the study of 1399 blood serum, samples from people bitten by Ixodid ticks in Predbaykalye region (East Siberia, Russia) and asking for medical care in the Center for prophylaxis of tick-borne diseases of Scientific Center of Family Health. Problems and. Human Reproduction. SB RAMS. The study showed, high, (up to 99,93 %) efficacy of early antibiotic course in preventing the Lyme disease in bitten peopl
