PARASITES & VECTORS 13/10/16 The influence of red deer space use on the distribution of Ixodes ricinus ticks in the landscape. Study area The data were collected in two areas on the west coast of Norway (Fig. 1).
The first area is in the middle of Sogn & Fjordane County, delimited by the fjords Sognefjorden in the south and Nordfjord in the north (study area SF). The climate is Atlantic with mild winters and cool summers. Meteorological 30-year averages (1961–1990) for this area are 2,270 mm of precipitation and a temperature of 6.0 °C annually ( met.no; Norwegian meteorological station no. 57170). The second area lies in the northern parts of Møre & Romsdal County and the western parts of Sør-Trøndelag County (study area MR).
Red deer GPS data and space use This study was based on GPS data from 73 adult (2 years or older) individuals of migratory and resident red deer, with 41 from Sogn & Fjordane and 32 from Møre & Romsdal County, Norway. We calculated the space use within red deer home ranges using the kernel methods  in the R-package “adehabitat” . SCIENCE DAILY 17/03/16 High levels of co-infection with pathogens and symbionts in ticks from the Ardennes. Ticks are small blood-feeding arachnids that can transmit diseases amongst animals and humans.
Researchers from the French National Institute for Agricultural research, INRA studied pathogen species and bacterial symbionts in tick species Ixodes ricinus. Publishing in PLOS Neglected Tropical Diseases, their findings showed all ticks contained symbiotic bacterial species and over half were infected with pathogens. The high level of co-infection with multiple pathogens and symbionts has important implications for diagnosis and treatment of tick-borne diseases. The researchers collected 267 adult female ticks between May and August 2012 from an 80 km transect in the French Ardennes.
Samples were taken from 6 forested areas and 3 with hedge networks. Of the 267 individually analyzed female ticks 45% were infected with at least 1 pathogen. "This work highlights the co-infection phenomenon in ticks, which may have important implications for human and animal health.

CDC EID – MARS 2016 – Au sommaire notamment: Borrelia miyamotoi and Candidatus Neoehrlichia mikurensis in Ixodes ricinus Ticks, Romania. Suggested citation for this article To the Editor: Ixodes spp. ticks are vectors for human and animal pathogens.
Ix. ricinus ticks are widely distributed, frequently reported to feed on humans, and the main vector for a large variety of tickborne pathogens (1). The effect of ticks and tickborne diseases on public health, animal health and welfare, and animal production appears to be an increasing global problem, which will lead to considerable economic costs (2). Borrelia miyamotoi is a spirochete that belongs to the relapsing fever group and causes symptoms similar to those of other relapsing fever group pathogens and Lyme borreliosis, including erythema migrans−like skin lesions (3).

Parasites & Vectors 2016 9:97 Larvae of Ixodes ricinus transmit Borrelia afzelii and B. miyamotoi to vertebrate hosts. We showed that larvae of I. ricinus can transmit Lyme disease spirochaetes.
An abstract in a conference book from 2002 claimed this finding before, but it was never published in a full research article . The possibility to culture B. afzelii from several organs of the rodents shows that the spirochaetes were viable and infectious. The rodents infected with B. afzelii subsequently facilitated transmission to other larvae, which successfully moulted to infected nymphs (71.4 % infectivity during the last challenge).
This resulted in a higher infection rate in the emerged nymphs compared to the infection rate of questing larvae. These results are in contradiction to the general idea that B. burgdorferi (s.l) can only be transmitted by nymphs (and adults), which acquired the infection as a larvae (or nymphs) during feeding [6–8]. In The Netherlands, 1.1 million people are bitten by one or more ticks annually .

FRONTIERS IN PUBLIC HEALTH 01/12/14 Ixodes ricinus and its transmitted pathogens in urban and peri-urban areas in Europe: new hazards and relevance for public health. Introduction Tick-borne infections are arthropod-borne diseases frequently reported worldwide.
Ticks are known to transmit a great variety of pathogenic agents producing the highest number of human disease cases compared to other vector-borne diseases in Europe (1, 2). Applied and Environmental Microbiology, 74 (23) , pp. 7118-7125 Relative importance of Ixodes ricinus and Ixodes trianguliceps a. + Author Affiliations The importance of Ixodes ricinus in the transmission of tick-borne pathogens is well recognized in the United Kingdom and across Europe.
However, the role of coexisting Ixodes species, such as the widely distributed species Ixodes trianguliceps, as alternative vectors for these pathogens has received little attention. EPINORTH 20/07/09 Tick-Borne Pathogens and Spread of Ixodes ricinus in Lithuania. AbstractTicks are among the most widely distributed blood-sucking arthropods in nature.
The main threat ticks pose to humans is their role as vectors of various pathogens that may cause disease, the most important in the European region being tick-borne encephalitis (TBE) and Lyme disease. Both diseases are transmitted by hard ticks of the Ixodes species, and Ixodes ricinus predominates in Europe. The main vector of tick-borne diseases in Lithuania is Ixodes ricinus, a tick that is found in temperate regions in Europe. In Lithuania 3,232 cases of TBE and 14,926 cases of Lyme disease were reported during 2000 – 2008.
