The first study of the prevalence and genetic diversity of Theileria equi and Babesia caballi in horses in Russia.

Equine piroplasmosis (EP) is a global worldwide infection, which can lead to the death of animals. Despite the causative agents of EP being well studied, there are no data on the distribution and genetic characteristics of EP agents in any region of Russia. In this study, blood samples from 750 horses from Novosibirsk province, Irkutsk province, and Altai region of Russian Siberia were examined for the presence of EP agents.

Novel Genetic Lineages of Associated with and Ticks.

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.

Multilocus genetic analysis indicates taxonomic status of "Candidatus Rickettsia mendelii" as a separate basal group.

To date, the phylogeny of Rickettsia spp. from basal groups is based on the small number of identified species. Thus, the finding of "Candidatus Rickettsia mendelii" in 2016 is of great interest.

Occurrence and clinical manifestations of tick-borne rickettsioses in Western Siberia: First Russian cases of Rickettsia aeschlimannii and Rickettsia slovaca infections.

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.

Genetic variability of Anaplasmataceae circulating in small mammals and ticks in an Ixodes persulcatus/Ixodes trianguliceps sympatric area in Russian Siberia.

A total of 705 rodents from Myodes, Microtus, and Apodemus genera, 396 adult questing Ixodes persulcatus, and 115 Ixodes larvae and nymphs taken from rodents (and then molted under laboratory conditions to nymphs and adults) were collected in 2013-2018 in Omsk province, Russian Siberia, and examined for the presence of Anaplasmataceae. DNA of Anaplasma phagocytophilum was detected in 29.5 % rodents, 3.

Long-term persistence of Anaplasma phagocytophilum and Ehrlichia muris in wild rodents.

Wild animals are reservoir hosts for a number of tick-transmitted agents, and long-term persistence of the agents is a key factor for their effective transmission from animal hosts to ticks. To study the persistence of Anaplasmataceae in rodents, 59 adult Myodes spp. voles (M.

Genetic and morphological characterization of Ixodes apronophorus from Western Siberia, Russia.

Genetic variability of I. apronophorus from Western Siberia, Russia was examined using the nuclear internal transcribed spacer 2 (ITS2) and mitochondrial 16S rRNA and cytochrome c oxidase subunit 1 (cox1) genes and compared to those of Ixodes persulcatus and Ixodes trianguliceps from the same site. The I.

Genetic variability of Rickettsia spp. in Dermacentor and Haemaphysalis ticks from the Russian Far East.

The Russian Far East is an endemic region for tick-borne rickettsioses. However, the prevalence and genetic variability of Rickettsia species in this region have not been extensively investigated. In this study, 188 Dermacentor silvarum, 439 Haemaphysalis concinna, and 374 Haemaphysalis japonica adult ticks were collected from four locations in Khabarovsk Province and three locations in Amur Province in the Russian Far East.

High prevalence of Babesia microti 'Munich' type in small mammals from an Ixodes persulcatus/Ixodes trianguliceps sympatric area in the Omsk region, Russia.

Babesia microti is a genetically diverse group of protozoan parasites whose life cycle is associated with both small mammals and Ixodes spp. ticks. In this study, the prevalence of different B.

Genetic variability of Rickettsia spp. in Ixodes persulcatus/Ixodes trianguliceps sympatric areas from Western Siberia, Russia: Identification of a new Candidatus Rickettsia species.

Rickettsia spp. are the causative agents of a number of diseases in humans. These bacteria are transmitted by arthropods, including ixodid ticks.

Genetic variability of Anaplasma phagocytophilum in ticks and voles from Ixodes persulcatus/Ixodes trianguliceps sympatric areas from Western Siberia, Russia.

Anaplasma phagocytophilum is a causative agent of granulocytic anaplasmosis in different mammals. The presence of A. phagocytophilum was assayed in Ixodes persulcatus, Ixodes trianguliceps ticks and Myodes spp.

Genetic variability of Anaplasma phagocytophilum in Ixodes persulcatus ticks and small mammals in the Asian part of Russia.

The specimens of 3552 questing adult Ixodes persulcatus and 1698 blood/tissue samples of small mammals collected in Ural, Siberia, and Far East of Russia were assayed for the presence of Anaplasma phagocytophilum by nested PCR based on the 16S rRNA gene. Totally, A. phagocytophilum was detected in 112 tick and 88 mammalian samples.
