Abstract:
: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, 3.8 % questing I. persulcatus, two molted adult I. persulcatus, and one molted adult Ixodes trianguliceps. Ehrlichia muris DNA was found in specimens from 12.1 % rodents, 3.0 % questing I. persulcatus, 14 % molted adult I. persulcatus, and one molted adult I. trianguliceps. Neoehrlichia mikurensis DNA was found in 0.6 % blood samples. It was suggested that in the studied area A. phagocytophilum and E. muris are mainly transmitted to small rodents by I. trianguliceps and I. persulcatus, respectively. Based on groEL gene sequence analysis, three phylogenetic clusters of A. phagocytophilum (clusters 4, 5, 6, according to Jaarsma et al., 2019) were identified. Most of genotyped A. phagocytophilum isolates obtained from rodents (87.6 %) and a single isolate found in a molted adult I. trianguliceps belonged to cluster 5. Cluster 6 contained 11.8 % genotyped specimens from rodents, and one questing and two molted adult I. persulcatus, while cluster 4 included specimens from 93 % genotyped questing I. persulcatus and one vole. The finding of A. phagocytophilum from clusters 5 and 6 in voles from the same sampling area indicated that clusters 5 and 6 segregate according to the tick-carriers, but not the geography. Most of the genotyped specimens of E. muris and N. mikurensis corresponded to typical genotypes detected in Asian Russia previously. In addition, new genetic variants of E. muris and N. mikurensis, which significantly differed from other known isolates and formed separate branches on phylogenetic trees, were identified in several voles.
