“…It constituted only 3.0% of the collected ticks, but can nevertheless be considered a major vector of various pathogens. It not only transmits A. phagocytophilum in the northern areas of Mongolia (Javkhlan et al 2014;Masuzawa et al 2014;Karnath et al 2016), but also borreliae (Kurtenbach et al 2006;Fomenko et al 2009) including the bird-associated B. garinii identified in the present study. It is the most important vector of TBEV in Mongolia (Baasandavga et al 2017).…”

Ticks are cosmopolitan vectors of numerous diseases, and detection of various pathogens in ticks can help to assess their distribution. In the current study, 528 adult ticks were collected from grazing animals or the ground in ten different Mongolian provinces. Dermacentor nuttalli constituted 76.1% of them and was found in all ecozones except the eastern desert. Dermacentor marginatus (8.3%), Dermacentor silvarum (1.1%) and Ixodes persulcatus (3.0%) were found in the northern forest areas and Hyalomma asiaticum (11.4%) only in the southern (semi-)desert. Of these, 359 ticks were subjected to DNA extraction and PCR was carried out to detect various pathogens. Anaplasma spp. was found in D. marginatus and D. nuttalli (2.5% positive each), including flagged specimen and identified as Anaplasma phagocytophilum. Borrelia spp. were found in 2.5% of the ticks (mostly in I. persulcatus) and identified as Borrelia garinii. Babesia spp. (40%) identified as Babesia caballi were detected in all five tick species including flagged Dermacentor spp. and I. persulcatus, and 3.5% of the ticks (all species except D. silvarum) were positive for Theileria spp. identified as Theileria equi. The piroplasms were found in all provinces. Tick-borne encephalitis virus was not detected. The results highlight the high risk of equine piroplasmosis in Mongolia, which is a concern for both the nomadic population who rely on horses for transport and for conservation of Przewalski's horses in Mongolia. In addition, zoonotic agents such as the avian B. garinii and A. phagocytophilum were also detected, outlining a high risk for exposed humans.

“…Ticks were detected that were dually infected with B. afzelii and B. garinii 20047 type (7.8z) and B. garinii NT29 and 20047 types (6.2z). Infection of B. garinii 20047 and NT29 types (identical to B. bavariensis-like Borrelia [20]) in I. persulcatus isolated from Mongolia were previously described by ospA sequencing analysis (19) and MLST (20). Furthermore, we previously showed that I. persulcatus carrying B. afzelii and B. garinii 20047 and NT29 types, but not B. burgdorferi sensu stricto, were found among isolates from around Moscow, Russia, which is a sympatric region for both I. persulcatus and I. ricinus (26).…”

PCR Detection of Anaplasma phagocytophilum and Borrelia burgdorferi in Ixodes persulcatus Ticks in Mongolia

A total of 1,345 Ixodes persulcatus ticks collected from northeastern China were investigated for the presence of Anaplasma phagocytophila and Borrelia burgdorferi by a nested polymerase chain reaction (PCR). Sixty-two (4.6%) ticks were positive for A. phagocytophila and 454 (33.8%) were positive for B. burgdorferi. Seven (0.5%) were coinfected with both agents. Sequence analysis of 919-basepair PCR amplicons revealed three types of A. phagocyto-phila. Type 1 was identical to the published sequences of A. phagocytophilas responsible for human granulocytic ehrlichiosis (HGE). The other two variants differed from the HGE agent sequence at one and four positions, respectively. These findings imply that infection with A. phagocytophila poses a potential health threat to both humans and animals in northeastern China, and that ehrlichiosis should be considered in the differential diagnosis of febrile patients with a history of tick bite, particularly when clinical manifestations are atypical for Lyme disease.
