Open AccessThree Babesia species in Ixodes ricinus ticks from migratory birds in Sweden
Migratory birds can cross geographical and environmental barriers and are thereby able to facilitate transmission of tick-borne pathogens both as carriers of infected ticks and as reservoirs of pathogenic micr...

Open AccessMigratory birds as disseminators of ticks and the tick-borne pathogens Borrelia bacteria and tick-borne encephalitis (TBE) virus: a seasonal study at Ottenby Bird Observatory in South-eastern Sweden
Birds can act as reservoirs of tick-borne pathogens and can also disperse pathogen-containing ticks to both nearby and remote localities. The aims of this study were to estimate tick infestation patterns on mi...

Open AccessFirst records of tick-borne pathogens in populations of the taiga tick Ixodes persulcatus in Sweden
The common tick Ixodes ricinus and the taiga tick I. persulcatus are the main tick vectors of Borrelia spirochaetes, TBE virus (TBEV) and of several other zoonotic pathogens in the western and eastern areas, resp...

Open AccessThe importance of wildlife in the ecology and epidemiology of the TBE virus in Sweden: incidence of human TBE correlates with abundance of deer and hares
Tick-borne encephalitis (TBE) is one tick-transmitted disease where the human incidence has increased in some European regions during the last two decades. We aim to find the most important factors causing the...

Open AccessFirst evidence of established populations of the taiga tick Ixodes persulcatus (Acari: Ixodidae) in Sweden
The tick species Ixodes ricinus and I. persulcatus are of exceptional medical importance in the western and eastern parts, respectively, of the Palaearctic region. In Russia and Finland the range of I. persulcatu...

Open AccessAssociation of environmental traits with the geographic ranges of ticks (Acari: Ixodidae) of medical and veterinary importance in the western Palearctic. A digital data set
We compiled information on the distribution of ticks in the western Palearctic (11°W, 45°E; 29°N, 71°N), published during 1970–2010. The literature search was filtered by the tick’s species name and an unambig...

Open AccessDriving forces for changes in geographical distribution of Ixodes ricinus ticks in Europe
Many factors are involved in determining the latitudinal and altitudinal spread of the important tick vector Ixodes ricinus (Acari: Ixodidae) in Europe, as well as in changes in the distribution within its prior ...

Acaricidal effects of Corymbia citriodora oil containing para-menthane-3,8-diol against nymphs of Ixodes ricinus (Acari: Ixodidae)
The toxicity of para-menthane-3,8-diol (PMD), the main arthropod-repellent compound in the oil of the lemon eucalyptus, Corymbia citriodora, was evaluated against nymphs of Ixodes ricinus using five methods (A–E)...

Repellency of methyl jasmonate to Ixodes ricinus nymphs (Acari: Ixodidae)
In our search for tick repellents of plant origin, to be used as alternatives to commercial arthropod repellents, we investigated the effect of the well known plant signaling compound methyl jasmonate (MJ) usi...

Repellency of MyggA® Natural spray (para-menthane-3,8-diol) and RB86 (neem oil) against the tick Ixodes ricinus (Acari: Ixodidae) in the field in east-central Sweden
In the field in south-central Sweden, we tested by randomised, standardised methodology the potential anti-tick repellent activity of two concentrations of MyggA® Natural spray (containing PMD) (4.2 and 3.2 g/m2)...

Infestation of mammals by Ixodes ricinus ticks (Acari: Ixodidae) in south-central Sweden
Infestation by Ixodes ricinus ticks on rodents, hares and cervids was examined at Bogesund, 10 km north of Stockholm, in south-central Sweden during 1991-1994 and on varying hares (Lepus timidus) at Stora Karl...

A Lyme borreliosis cycle in seabirds and Ixodes uriae ticks
THE Lyme disease spirochaete, Borrelia burgdorferi s.l. , is the only Borrelia known to infect both mammals and birds1. The main vertebrate reservoirs of B. burgdorferi are thought to be various small and interme...
