Article Synopsis
- Equine piroplasmosis (EP) is a serious global infection that can be fatal to horses, with this study focusing on its presence in Siberia, Russia, where data was previously lacking.
- Blood samples from 750 horses across three regions in Siberia revealed that Theileria equi was present in 60.4% and Babesia caballi in 7.2% of the samples, indicating a significant prevalence of these pathogens.
- Genetic analysis showed T. equi was mainly of two genotypes, while B. caballi exhibited high genetic diversity with seven variants found, leading to the identification of new genetic clusters that have broadened existing knowledge about this pathogen's diversity.
is an insufficiently studied nidicolous tick species. For the first time, the prevalence and genetic diversity of spp. in , , and ticks from their sympatric habitats in Western Siberia were investigated.

- The spotted fever group in the Rickettsia genus includes newly identified species worldwide, including "Candidatus Rickettsia thierseensis" found in Austria in 2020.
- Genetic analysis revealed that the sequences of "Candidatus R. thierseensis" closely match those of "Candidatus Rickettsia uralica," originally identified in Russia in 2015.
- Comparison of genetic loci showed 100% identity in several gene regions and only minor differences in others, suggesting that these two species may actually be the same.
Rickettsia sibirica subsp. sibirica is a main agent of tick-borne rickettsioses in Western Siberia, Russia. Recently, the first cases of Rickettsia raoultii infection in patients hospitalized in Novosibirsk Province were described.
