Рекогносцировочное исследование детей из Тофаларии на клещевые инфекции

The serum samples from children who reside in Tofalaria were studied for presence of antibodies against four tick-borne infections, including tick-borne encephalitis virus (TBEV), Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum, Ehrlichia muris and E. chaffensis. In total, 16 % of samples contained IgG antibodies against TBEV. Of them, one child (11,1 %) belonged to Tofalar nationality, two children (15,4 %) were half-breed and four (18,2 %) belonged to Russian nationality. In group of children with positive serum samples one Russian boy had antibodies to TBEV and B. burgdorferi sensu lato simultaneously. The titers were 1:1900 and 1:100 correspondently. Obtained results testify the need for development of prophylaxis of tick-borne infections.
