Ixodes ricinus Strains in Europe

Zentralblatt für Bakteriologie, 1998
An analysis of cuticular hydrocarbons (CH) of unfed adult Ixodes ricinus ticks collected throughout Europe showed that there are 10 distinct I. ricinus groups. Studies on the seasonal and annual consistency of CH composition and possible effects of host and environmental factors suggested that CHs may be used as a genuine genetic marker for I. ricinus.

Differential diagnosis of Ixodes ricinus and Ixodes persulcatus: nymphs and larvae

Experimental and Applied Acarology, 2018
We developed a method for differential diagnosis of nymphs and larvae of sheep (Ixodes ricinus (L.)) and taiga (I. persulcatus Sch.) ticks (Parasitiformes: Ixodidae) which allows to identify live material in the field.

Hatching of the Egg of Ixodes ricinus L

Nature, 1946
DURING the course of an ecological investigation, we have had abundant opportunity for observing eggs of Ixodes ricinus L. A recent communication1 on the mechanism of the hatching process raises some points of interest.

Diversity of Babesia in Ixodes ricinus ticks in Poland

Advances in Medical Sciences, 2012
The aims of this study were: (1) to estimate Babesia prevalence in the most common species of tick in Poland, Ixodes ricinus, in two recreational areas (Urwitałt in the Mazury Lake District and Bielański Forest in Warsaw), and (2) to evaluate the molecular diversity of Babesia isolates in questing I. ricinus in Poland.Questing ticks were collected from

Ixodes ricinus (Ixodidae)

2009
Die vorliegende Arbeit hatte die Untersuchung der saisonalen Aktivität von I. ricinus in Kombination mit der Prävalenz des FSME-Virus in Zecken an ausgewählten Stand¬orten in Bayern zum Ziel. Hierzu wurden von April 2006 bis Dezember 2007 in den Kreisen München, Dachau, Rosenheim, Amberg und Passau in monatlichen Ab¬stän¬den Zecken gesammelt ...

Seasonal distribution of borreliae in Ixodes ricinus ticks

Zentralblatt für Bakteriologie, 1994
Ixodes ricinus ticks were collected by flagging vegetation of a mixed oak forest in South Moravia (Czech Republic) at regular two-month intervals from March 1991 to March 1992 and examined for borreliae by darkfield microscopy. Mean annual proportions of infected ticks were 17.2% (15.4% to 21.2% monthly) in females (F), 18.6% (11.8% to 25.9%) in males (

The extensible alloscutal cuticle of the tick, Ixodes ricinus

Insect Biochemistry and Molecular Biology, 2005
The proteins in the distensible alloscutal cuticle of the blood-feeding tick, Ixodes ricinus, have been characterized by electrophoresis and chromatography, two of the proteins were purified and their total amino acid sequence determined. They show sequence similarity to cuticular proteins from the spider, Araneus diadematus, and the horseshoe crab ...

The experimental transmission of Babesia divergens by Ixodes ricinus

Experimental Parasitology, 1963
Abstract A strain of Babesia divergens , previously maintained by needle passage in splenectomized calves, has been transmitted in the laboratory by larvae and on one occasion by nymphs of Ixodes ricinus . The infection appeared to be transmitted most readily by larvae after infection of the previous adult stage. The techniques described could be
