A large-scale screening for the taiga tick, Ixodes persulcatus, and the meadow tick, Dermacentor reticulatus, in southern Scandinavia, 2016
2019
Abstract The taiga tick, Ixodes persulcatus, has previously been limited to eastern Europe and northern Asia, but recently its range has expanded to Finland and northern Sweden. The species is of medical importance, as it, along with a string of other pathogens, may carry the Siberian and Far Eastern subtypes of tick-borne encephalitis virus. These subtypes appear to cause more severe disease, with higher fatality rates than the central European subtype. Until recently, the meadow tick, Dermacentor reticulatus, has been absent from Scandinavia, but has now been detected in Denmark, Norway and Sweden. Dermacentor reticulatus carries, along with other pathogens, Babesia canis and Rickettsia r…
Detection of tick-borne encephalitis virus in I. ricinus ticks collected from autumn migratory birds in Latvia.
2014
Birds have a potential of spreading ticks via bird migration routes. In this study, we screened 170 ticks removed during autumn 2010 from 55 birds belonging to 10 species for the presence of tick-borne encephalitis virus (TBEV). In total, TBEV RNA was detected in 14% of I. ricinus tick samples obtained from different birds species. The results of this study indicate the possible role of migrating birds in the dispersal of TBEV-infected ticks along the southward migration route.

Untersuchungen zur Bedeutung der Frühsommer-Meningoenzephalitis in Rheinland-Pfalz
2002
Within the scope of a prospective clinical study during 2001 in Rhineland-Palatinate specimen from sera and cerebrospinal fluids of 163 patients with suspected meningitis were controlled in an enzyme immunoassay concerning a TBE infection. Questionable results were checked via a neutralisation test. In no case such an infection was confirmed. No virus specific nucleic acids could be detected in 998 nymphs and adults of Ixodes ricinus in an additional investigation in 2000. Therefore Rhineland-Palatinate has to be considered as a region with low virus prevalence. A general recommendation for vaccination is not necessary.
Tick-borne encephalitis virus, Borrelia burgdorferi sensu lato, Borrelia miyamotoi, Anaplasma phagocytophilum and Candidatus Neoehrlichia mikurensis …
2018
The aim of this study was to determine the occurrence of tick-borne pathogens of medical importance in questing ticks collected from five recreationally used islands along the Norwegian coastline. Furthermore, since coinfection may affect the disease severity, this study aimed to determine the extent of coinfection in individual ticks or co-localization of tick-borne pathogens. In all, 4158 questing Ixodes ricinus ticks were analyzed. For detection of tick-borne encephalitis virus (TBEV), nymphs (3690) were analyzed in pools of ten. To detect Borrelia burgdorferi sensu lato, B. miyamotoi, Anaplasma phagocytophilum and Candidatus Neoehrlichia mikurensis, 468 nymphs were analyzed individually…
A lethal Tick-Borne Encephalitis (TBE) due to TBE virus in Sicily (Italy): A case of IgG+/IgM-response?
2018
Tick-borne encephalitis (TBE) is an important viral infection of the central nervous system with high morbidity and mortality. With the increase of tourism TBE is becoming a problem also outside endemic regions. Italy is considered a country with low incidence of TBE and geographically restricted to the central and north eastern part of the country. In the south of Italy there is no evidence of disease presence, but neither is there much evidence of its absence. We report our experience about a lethal case of meningoencephalitis with a single-phase clinical course of the disease likely due to TBEV infection in a 13-year-old man. This is the first report of an autochthonous case of TBE in Si…
Ērču encefalīts Latvijā un Norvēģijā
2015
Problēmas aktualitāte: Saslimstība ar ērču encefalītu pieaug Ziemeļeiropā un ir endēmiska Centrālajā un Austrumeiropā. Ir svarīgi izvērtēt profilaktiskos un ārstniecības aspektus šai nenotveramai slimībai. Darba mērķis: Bija salīdzināt ērču encefalīta prevelanci Norvēģijā un Latvijā un analizēt dažādas klīniskās izpausmes un ārstēšanu, lai to optimizētu un samazinātu pacientu slimnīcā pavadīto laiku. Materiāls un metodes: Retrospektīvs pētījums, kurā tika iekļauti stacionētie pacienti ar diagnozi ērču encefalīts no MSIS datu bāzes un no P.Stradiņa KUS slimības vēsturu arhīva 2009-2014.gadā un LIC arhīva 2014.gadā. Pacientu vestures tika analizētas atbilstoši pētījumam radītajam formulāram a…
