Borrelia miyamotoiin host-seekingIxodes ricinusticks in England

Abstract

This paper reports the first detection of Borrelia miyamotoi in UK Ixodes ricinus ticks. It also reports on the presence and infection rates of I. ricinus for a number of other tick-borne pathogens of public health importance. Ticks from seven regions in southern England were screened for B. miyamotoi, Borrelia burgdorferi sensu lato (s.l.), Anaplasma phagocytophilum and Neoehrlichia mikurensis using qPCR. A total of 954 I. ricinus ticks were tested, 40 were positive for B. burgdorferi s.l., 22 positive for A. phagocytophilum and three positive for B. miyamotoi, with no N. mikurensis detected. The three positive B. miyamotoi ticks came from three geographically distinct areas, suggesting a widespread distribution, and from two separate years, suggesting some degree of endemicity. Understanding the prevalence of Borrelia and other tick-borne pathogens in ticks is crucial for locating high-risk areas of disease transmission.

Borrelia miyamotoi: a widespread tick-borne relapsing fever spirochete

“…[17][18][19]. Recent phylogenetic analysis revealed genetic differences between the Asian, American, and European B. miyamotoi isolates [9,20]. Whether these genetic differences correlate with differences in vector competence ( Figure 1B), host range, Unweighted pair group method with arithmetic mean-based dendrogram produced using fragments of the glpQ gene (366 bp) from different Borrelia miyamotoi isolates.…”

Neoehrlichiosis: an emerging tick-borne zoonosis caused by Candidatus Neoehrlichia mikurensis

“…Based on the current knowledge of the geographical distribution of Ca. N. mikurensis in questing I. ricinus (Table 1), neoehrlichioses in (immune-compromised) patients are expected to occur basically all over Europe (Hansford et al 2014;Jahfari et al 2012). Less than half of these patients recalled tick exposure, making this a poor predictor of neoehrlichiosis.…”

Borrelia miyamotoi: egy újabb, humán patogén, kullancs által terjesztett, visszatérő lázat okozó baktérium

“…A B. miyamotoi nagy területen elterjedt, jelenleg 18 európai országból van adat az előfordulásáról (1. táblá-zat) [8,9,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. A növényzetről gyűjtött közönséges kullancsokban a fertőzöttek aránya 0,18% és 4,8% közöt-ti.…”
