Abstract
In Slovakia, little knowledge is available on the occurrence, hosts and vectors of Borrelia miyamotoi of the relapsing fever group. In the current study, 2160 questing and rodent-attached ticks of six species (Ixodes ricinus, Ixodes trianguliceps, Dermacentor marginatus, Dermacentor reticulatus, Haemaphysalis concinna and Haemaphysalis inermis), 279 fleas belonging to 9 species (Ctenophthalmus agyrtes, Ctenophthalmus solutus, Ctenophthalmus assimilis, Megabothris turbidus, Amalareus penicilliger, Hystrichopsylla orientalis, Ctenophthalmus uncinatus, Doratopsylla dasycnema and Nosopsyllus fasciatus) and skin biopsies from 245 small mammals belonging to eight species (Apodemus agrarius, Apodemus flavicollis, Apodemus uralensis, Myodes glareolus, Crocidura leucodon, Micromys minutus, Microtus arvalis, Microtus subterraneus) were screened for the presence of B. miyamotoi DNA. The overall prevalence of B. miyamotoi found in questing and rodent-attached ticks was 1.8% (23 positive/1260 examined) and 3.4% (31 positive/900 examined), respectively. Borrelia miyamotoi was detected in questing I. ricinus, rodent-attached I. ricinus and H. inermis ticks, and in one male of the common vole (M. arvalis) in different habitats (mainly rural) in eastern Slovakia. However, B. miyamotoi was not found in any of the tested fleas. Our findings indicate that rural habitats with different species of tick vectors and hosts are appropriate for the occurrence of B. miyamotoi.

Abstract
We collected blood and tick samples in eastern Maryland to quantify vector-borne pathogen exposure and infection in healthy cats and to assess occupational disease risk to veterinary professionals and others who regularly interact with household pets. Thirty-six percent of healthy cats parasitized by ticks at time of examination (9/25) were exposed to, and 14% of bloods (7/49) tested PCR-positive for, at least one vector-borne pathogen including several bloods and ticks with Borrelia miyamotoi, a recently recognized tick-borne zoonotic bacterium. There was no indication that high tick burdens were associated with exposure to vector-borne pathogens. Our results underscore the potential importance of cats to human vector-borne disease risk.

Abstract
Borrelia miyamotoi, recently recognized as a human pathogenic spirochete, was isolated from Ixodes persulcatus and I. ovatus in northern Mongolia and Honshu Island, a major island in Japan. Although no human B. miyamotoi infections have been reported in Mongolia, the prevalence of B. miyamotoi in ticks from Mongolia is higher than that in ticks from Hokkaido, Japan, where human cases have been reported. Moreover, the multi-locus sequence analysis of cultured isolates revealed that B. miyamotoi isolates in Mongolia belong to the Siberian type, a sequence type that was originally reported from isolates from I. persulcatus in Hokkaido. Thus, there is a possibility of unrecognized human B. miyamotoi infections in Mongolia. Moreover our data support the hypothesis of clonal expansion of the Siberian type B. miyamotoi. In contrast, although the isolates were found to belong to the Siberian type B. miyamotoi, two isolates from I. persulcatus in Honshu Island were identified to be of a different sequence type. Furthermore, B. miyamotoi isolates from I. ovatus were distinguishable from those from I. ricinus complex ticks, according to genetic analysis. In this study, we show that there may be some genetic diversity among B. miyamotoi in ticks from Honshu Island.

INFECTION GENETICS AND EVOLUTION 2015; 31:257-62.

Abstract
Borrelia miyamotoi, a member of the relapsing fever group borreliae, was first isolated in Japan and subsequently found in Ixodes ticks in North America, Europe and Russia. Currently, there are three types of B. miyamotoi: Asian or Siberian (transmitted mainly by Ixodes persulcatus), European (Ixodesricinus) and American (Ixodesscapularis and Ixodespacificus). Despite the great genetic distances between B. miyamotoi types, isolates within a type are characterised by an extremely low genetic variability. In particular, strains of B. miyamotoi of Asian type, isolated in Russia from the Baltic sea to the Far East, have been shown to be identical based on the analysis of several conventional genetic markers, such as 16S rRNA, flagellin, outer membrane protein p66 and glpQ genes. Thus, protein or rRNA - coding genes were shown not to be informative enough in studying genetic diversity of B. miyamotoi within a type. In the present paper, we have attempted to design a new multilocus technique based on eight non-coding intergenic spacers (3686bp in total) and have applied it to the analysis of intra-type genetic variability of В. miyamotoi detected in different regions of Russia and from two tick species, I. persulcatus and Ixodespavlovskyi. However, even though potentially the most variable loci were selected, no genetic variability between studied DNA samples was found, except for one nucleotide substitution in two of them. The sequences obtained were identical to those of the reference strain FR64b. Analysis of the data obtained with the GenBank sequences indicates a highly homogeneous genetic background of B. miyamotoi from the Baltic Sea to the Japanese Islands. In this paper, a hypothesis of clonal expansion of B. miyamotoi is discussed, as well as possible mechanisms for the rapid dissemination of one B. miyamotoi clone over large distances.

Abstract
Spirochetes of the Borrelia burgdorferi sensu lato complex are the causative agent of Lyme borreliosis which is widespread in Russia. Nowadays, three clinically important B. burgdorferi s.l. genospecies, B. afzelii, B. garinii, B. bavariensis sp. nov., can be found in Russia, as well as B. miyamotoi, which belongs to the tick-borne relapsing fever group of spirochetes. Several techniques have been developed to differentiate Borrelia genospecies. However, most of them do not allow detection of all of these genospecies simultaneously. Also, no method based on the RT-PCR TaqMan approach has been proposed to differentiate the genetically closely related species B. bavariensis and B. garinii. In the present paper, we investigated two species of ticks, I. persulcatus and I. pavlovskyi (1343 and 92 adults, respectively). Two sets of primers and probes for RT-PCR, with uvrA, glpQ and nifS genes as targets, were designed to detect four Borrelia genospecies in positive samples. The average prevalence of Borrelia sp. was about 40%, with B. afzelii as the most prevalent genospecies. Mixed infections of B. bavariensis and B. garinii were found to be extremely rare. While B. bavariensis was predominant in I. persulcatus, I. pavlovskyi ticks were infected exclusively by B. garinii. The proposed technique proved to be efficient in selection of individual Borrelia species for further genetic analysis, in particular, for multilocus sequence typing. Also, it could be applied for the differentiation of Borrelia genospecies in clinical material.

Abstract
Background Wild birds contribute to maintenance and dissemination of vectors and microbes, including those that impact human, domestic animal, and wildlife health. Here we elucidate roles of wild passerine birds, eastern cottontail rabbits (Sylvilagus floridanus), and Ixodes dentatus ticks in enzootic cycles of two spirochetes, Borrelia miyamotoi and B. andersonii in a region of Michigan where the zoonotic pathogen B. burgdorferi co-circulates. Methods Over a four-year period, wild birds (n = 19,631) and rabbits (n = 20) were inspected for tick presence and ear tissue was obtained from rabbits. Samples were tested for Borrelia spirochetes using nested PCR of the 16S-23S rRNA intergenic spacer region (IGS) and bidirectional DNA sequencing. Natural xenodiagnosis was used to implicate wildlife reservoirs. Results Ixodes dentatus, a tick that specializes on birds and rabbits and rarely bites humans, was the most common tick found, comprising 86.5% of the 12,432 ticks collected in the study. The relapsing fever group spirochete B. miyamotoi was documented for the first time in ticks removed from wild birds (0.7% minimum infection prevalence; MIP, in I. dentatus), and included two IGS strains. The majority of B. miyamotoi-positive ticks were removed from Northern Cardinals (Cardinalis cardinalis). Borrelia andersonii infected ticks removed from birds (1.6% MIP), ticks removed from rabbits (5.3% MIP), and rabbit ear biopsies (5%) comprised twelve novel IGS strains. Six species of wild birds were implicated as reservoirs for B. andersonii. Frequency of I. dentatus larval and nymphal co-feeding on birds was ten times greater than expected by chance. The relatively well-studied ecology of I. scapularis and the Lyme disease pathogen provides a context for understanding how the phenology of bird ticks may impact B. miyamotoi and B. andersonii prevalence and host associations. Conclusions Given the current invasion of I. scapularis, a human biting species that serves as a bridge vector for Borrelia spirochetes, human exposure to B. miyamotoi and B. andersonii in this region may increase. The presence of these spirochetes underscores the ecological complexity within which Borrelia organisms are maintained and the need for diagnostic tests to differentiate among these organisms.
