Clinical-Epidemiological Peculiarities of the Tick-Borne Borrelioses Registered in the Trans-Baikal Territory

Complex analysis of the data on epidemiology and clinical picture of the tick-borne borrelioses in the territory of the Trans-Baikal Region over the last decade since 2003 to 2012 has demonstrated that there is a distinct upward tendency as concerns its morbidity rates. Spotted have been the potentially hazardous, as regards the infection, areas. Highest incidence rates are registered between May-July among adult men, and erythema form of the disease prevails. Based on the results of molecular-genetic investigation of Ixodidae ticks, for the first time ever in the territory of the Dul’durginsk Region identified has been circulation of Borrelia garinii , and B. afzelii , pathogenic for humans bacterial species of Borrelia genus

Assessment of Epizootiological-Epidemiological Situation on Natural Focal Infections in Aleksandrovsk-Sakhalin Territory of the Sakhalin Region

Objective of the work was to carry out complex assessment of the current state of epizootic activity and epidemiological significance of the infectious disease natural foci in the Aleksandrovsk-Sakhalin territory of the Sakhalin Region. Trapped were 56 samples of small mammals in July, 2010; collected were 180 specimens of taiga tick imago, caught were 1000 specimens of mosquitoes. 223 samples of blood sera were taken from residents of the region. All the field data were tested to detect specific antibodies, antigens and genetic material of agents. Based on the results of epizootiological investigations, serological and molecular-genetic assays, demonstrated was the occurence of natural foci of leptospirosis, tularemia, tick-borne encephalitis, borreliosis, rickettsiosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, West Nile fever, Inco fever, Batai and Geto fevers, as well as HFRS with varying degree of activity manifestation in the territory of the region. Isolated was tick-borne encephalitis virus from mosquitoes
