“…Under these circumstances, B. miyamotoi infection prevalences in nymphal and adult I. pacificus approach and may exceed those of B. burgdorferi [20,28]. In Europe, the range of B. miyamotoi infection rates reported in I. ricinus nymphal ticks is 0–3.2% [3,9,15–16,18,22–26,30]. Infection rates in I. scapularis in Canada and I. persulcatus in Russia fall within the range of B. miyamotoi infection detected in I. scapularis ticks in the United States [10,19].…”

Borrelia miyamotoi is a relapsing fever Borrelia group spirochete that is transmitted by the same hard-bodied (ixodid) tick species that transmit the agents of Lyme disease. It was discovered in 1994 in Ixodes persulcatus ticks in Japan. B. miyamotoi species phylogenetically cluster with the relapsing fever group spirochetes, which usually are transmitted by soft-bodied (argasid) ticks or lice. B. miyamotoi infects at least six Ixodes tick species in North America and Eurasia that transmit Lyme disease group spirochetes and may use small rodents and birds as reservoirs. Human cases of B. miyamotoi infection were first reported in 2011 in Russia and subsequently in the United States, Europe, and Japan. These reports document the public health importance of B. miyamotoi, as human B. miyamotoi infection appears to be comparable in frequency to babesiosis or human granulocytic anaplasmosis in some areas and may cause severe disease, including meningoencephalitis. The most common clinical manifestations of B. miyamotoi infection are fever, fatigue, headache, chills, myalgia, arthralgia, and nausea. Symptoms of B. miyamotoi infection generally resolve within a week of the start of antibiotic therapy. B. miyamotoi infection should be considered in patients with acute febrile illness who have been exposed to Ixodes ticks in a region where Lyme disease occurs. Because clinical manifestations are non-specific, etiologic diagnosis requires confirmation by blood smear examination, PCR, antibody assay, in vitro cultivation, and/or isolation by animal inoculation. Antibiotics that have been used effectively include doxycycline for uncomplicated B. miyamotoi infection in adults and ceftriaxone or penicillin G for meningoencephalitis.

“…This species was first identified in 1995 by Fukunaga and collaborators in Ixodes persulcatus ticks and in a small mammal (Apodemus argenteus), at Hokkaido, Japan (Fukunaga et al 1995). Since then, B. miyamotoi has been found in several ticks classified in the Ixodes genus in North America, Europe, and Asia, revealing an extensive geo-graphic distribution (Geller et al 2012, Cochez et al 2014, Cosson et al 2014, Dibernardo et al 2014, Hansford et al, 2014, Kiewra et al 2014, Takano et al 2014.…”

Borrelia miyamotoi, a relapsing fever spirochete, has been found recently in Ixodes ricinus ticks; however, little is known about its spatial distribution and potential local impact on human health. A total of 640 ticks (447 nymphs and 193 adults) collected throughout Portugal were analyzed using two nested PCR protocols, one targeting the flagellin gene and the other the internal transcribed space region between the 5S and the 23S rRNA. As a result, B. miyamotoi was detected, for the first time, in one guesting I. ricinus nymph collected in the Lisboa district. In addition, a prevalence of 11% (71/640) for B. burgdorferi sensu lato was obtained. Even though no human relapsing fever cases due to infection by B. miyamotoi have been reported yet in Portugal, surveillance must be improved to provide better insight into the prevalence and distribution of this spirochete in ticks.

“…Borrelia afzelii and Borrelia garinii are dominant genospecies in ticks in Europe [21][22][23][24][25][26][27][28][29]. In North America there is one major genospecies -Borrelia burgdorferi sensu stricto [16].…”

Introduction. During feeding, the tick sucks blood from the host along with the pathogens that are in the blood, simultaneously exchanging its own pathogens with the host. Humans can also be a host. It is important to understand the most typical circumstances in which people might become infected with Borrelia burgdorferi. This knowledge will help to prepare health education programmes aimed at the prevention of Lyme disease and other tick-borne diseases. Objective. The aim of the study was to determine the percentage of ticks infected with Borrelia burgdorferi sensu lato, depending on the circumstances of getting bitten. Materials and method. The research material consisted of ticks acquired from people who had been bitten, and questionnaires completed by these people. 510 ticks were acquired from 257 females and 253 males. Following delivery of a tick for testing, the stage of its development was determined and a molecular assay of Borrelia burgdorferi DNA performed. Results. A positive result of the nested-PCR test was obtained in 78 ticks, which represents 15.30% of all ticks. The infected ticks were collected from male (41 ticks -52.56%) and female subjects (37 ticks -47.44%). The biggest number of infected ticks were collected in autumn (54 ticks -69.23%) and from people who had been into forests (44 ticks -56.41%). Among the people from whom the infected ticks were acquired, the dominating group included persons over 16 years of age (53 persons -67.95%) and children aged 0-5 years (16 persons -20.51%). One in four infected ticks were acquired from the southwestern (20 ticks -25.64%) and eastern regions of Poland (21 ticks -26.92%). Conclusion. Infestation of ticks infected with Lyme disease spirochete in this study proved to be variable and depend on the season, the area of tick attack and the region in Poland. The results of the study clearly show that ticks infected with Borrelia burgdorferi inhabit all regions of Poland. The results are consistent with National Institute of Hygiene data which indicates that Lyme disease cases are recorded in all regions of Poland.
