b a ckground: the present study aimed to demonstrate the seasonal activities of ixodes ricinus at the pasture level and on the host. m e t hods: a vast pasture in amol countryside (mazandaran province, iran) which had the potential for a considera- ble number of cattle and sheep to graze was chosen. tick sampling from the skin of 130 cattle and 130 sheep were collected every month interval. sim...

Human tick-borne diseases that are transmitted by Ixodes ricinus, such as Lyme borreliosis and tick borne encephalitis, are on the rise in Europe. Diminishing I. ricinus populations in nature can reduce tick exposure to humans, and one way to do so is by developing an anti-vector vaccine against tick antigens. Currently, there is only one anti-vector vaccine available against ticks, which is a ...

in the present study, pathogenicity of four native strains of entomopathogenic fungus; metarhizium anisopliae, was studied against adult stage of ixodes ricinus. for this purpose a total number of 180 adult ticks were examined in triplicate. thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. samples were incubated in separate pet...

A strain of Greek goat encephaltitis virus was isolated from engorged Ixodes ricinus ticks that had fed on goats in northern Greece. The strain was almost identical to the prototype strain isolated 35 years ago.

This article documents the public availability of a global transcriptome comparison between Lyme disease tick vectors, Ixodes scapularis and Ixodes ricinus.

From three endemic locations of erythema chronicum migrans disease in North Rhine-Westphalia, Germany, we recovered 19 isolates of a spirochete from Ixodes ricinus ticks. The infection rate in adult ticks was 16 percent. The isolated spirochete is immunologically related to the Ixodes dammini spirochete, Borrelia duttoni, and Treponema pallidum. Using indirect immunofluorescence, the sera of 90...

A total of 174 unfed Ixodes ricinus ticks (104 nymphs, 36 males, and 34 females) collected in the Roztocze National Park in eastern Poland were examined by the PCR and nested PCR methods for the presence of hantavirus RNA. None of the examined Ixodes ricinus specimens showed the presence of the hantavirus-specific RNA, in spite of using 2 genetic markers and the clearly positive results obtaine...

To determine characteristics of natural transmission of Babesia sp. EU1 and B. divergens by adult Ixodes ricinus ticks, we examined tick salivary gland contents. We found that I. ricinus is a competent vector for EU1 and that their sporozoites directly invade erythrocytes. We conclude that EU1 is naturally transmitted by I. ricinus.

INTRODUCTION We previously identified tick salivary lectin pathway inhibitor (TSLPI) in Ixodes scapularis, a vector for Borrelia burgdorferi sensu stricto (s.s.) in North America. TSLPI is a salivary protein facilitating B. burgdorferi s.s. transmission and acquisition by inhibiting the host lectin complement pathway through interference with mannose binding lectin (MBL) activity. Since Ixodes ...
