[Emergence of tick-borne spotted fever group rickettsiosis in Moscow].

Aim: Analysis of clinical cases of tick-borne spotted fever (TSF) group rickettsiosis in 2005 - 2010.
Materials and Methods: General clinical, biochemical and serological parameters were determined in 10 tick-borne spotted fever group rickettsiosis patients who had visited various geographical regions of the World.
Results: TSF group rickettsiosis diagnostic criteria, optimal serological diagnostics timing were determined. Possible diagnostic errors, features of serological diagnostics and antibacterial therapy of this nosologic form are discussed.
Conclusion: Indication for TSF examination are primarily epidemiologic including tick attachment indication and clinical data. Serological studies are positive only in 3 - 4 weeks after the onset of the infection and thus can not be used for early diagnostics.
