Abstract

SUMMARYObjective.The aim of this work was to study the prevalence and genetic diversity ofBabesiainIxodes persulcatusticks and small mammals from Ural and Siberia in Russia.Methods.In total, 481 small mammals and 922 questing adultI. persulcatusfrom North Ural (Sverdlovsk region) and West Siberia (Novosibirsk region) were examined for the presence ofBabesiaby nested PCR based on the 18S rRNA gene.Results.Babesia microtiof the ‘Munich’-type was found in 36·2% of blood samples of the small mammals from the Sverdlovsk region andB. microtiof the ‘US’-type in 5·3% of the animals from the Novosibirsk region.BabesiaDNA was not detected in 133 analysedI. persulcatusfrom the Sverdlovsk region; however, it was found in 24 of 789 ticks from the Novosibirsk region. Three distinctBabesiaspecies were detected inI. persulcatus. B. microti‘US’-type was identified in 10 ticks,Babesiaclosely related toB. divergens/B. capreoliin 2 ticks, andBabesiaclosely related toB. venatorum(EU1) in 12 ticks.Conclusion.To our knowledge, this is the first detection ofBabesia sensu strictoinI. persulcatusticks and ofB. microtiinI. persulcatusin the Asian part of Russia.
