Ixodes ricinus is the common tick infesting farmstock in Wales. Dermacentor reticulatus is recorded on cattle and sheep on two farms in N. Cardiganshire.I. ricinus is widely distributed in the four major grassland zones of N.W. Cardiganshire. The most extensive areas of tick infestation are found on the marginal and hill farms. In lowland areas, except on extensive stretches of marshland, infested pastures are confined to isolated tracts of badly managed or poorly drained land. Infested grazings are invariably “rough” and contain one of the following plants as dominant: Festuca spp., Agrostis spp., Molinia caerulea, Nardus stricta, Pteris aquilina or Juncus spp. The degree of infestation of cattle depends on the relative area of the available grazing land colonised by the tick. Continuous stocking of infested pastures results in heavy infestations and vice versa.Bovine piroplasmosis is the major tick-borne disease in N.W. Cardiganshire and predominates in the lowland districts. Outbreaks of the disease on marginal and hill farms are generally infrequent. Reasons are suggested for this phenomenon. Tick pyaemia is confined to lambs on hill grazings. The incidence of this disease is low.The distribution of the tick in Wales and the border counties of Hereford and Salop shows a general relationship to areas of rough grazing. The tick is widespread in the western counties and is almost absent in the border counties. Radnorshire and Breconshire are interesting in that they have few infested farms in relation to the extensive nature of the “rough” grazing. A survey has also been conducted of the incidence of bovine piroplasmosis in Wales.

The most of ixodes ticks in Tula region belongs to the group of pasture mites. It is generally accepted to estimate the tick’s contamination by the tick-borne encephalitis virus and raoueti inducing Lyme Borellia. The aim of the present work was to educe the aetiologic agents of the set of potentially-enable infections out of ticks Dermacentor reticulatus, Ixodes ricinus and Ixodes сrenulatus collected at the different terrains of Tula Region by PCR method. The results: a considerable number of pathogenic rickettsiae R. raoultii was educes from the ticks D. reticulatus, which including them as the component of mixed infection together with the human monocytic ehrlichiosis agent. R. raoultii was determined in more than a half of the cases in ticks I. ricinus including the mixed infection together with ticks’ borreliosis virus and Kemerovo fever agent. Conclusion. The reasons, induced the quantity changes of the ticks’ distribution at Tula Region terrains, apparently promote the rise in frequency of the ticks contamination with the agents of herd tick-transmissive infection. It demand an infectiologist’s attention rise and dictate the necessity of the above mentioned diseases monitoring as well as Fr. tularensis, the tick-borne encephalitis virus and Lyme disease.

Ticks parasitizing on dogs belong to mites of the order Ixodida, class Arachnida. In Poland the occurrence of four species has been recorded most frequently: Ixodes ricinus, I. hexagonus, I. crenulatus and Dermacentor reticulatus. Their importance is due to the fact that they are vectors of many dangerous diseases of humans and animals. The subject of the present study were ticks collected from dogs, patients of several veterinary clinics from the urban agglomeration of the city of Olsztyn. Ticks were collected from May to June in eight consecutive years: 2009–2016. The dominant species was I. ricinus (60.14%) in relation to D. reticulatus (39.71%). In two consecutive years, 2011–2012, single females of Rhipicephalus sanguineus were also identified, an exceptional finding of this species in our country. In D. reticulatus, nymphs predominated over females (23.74% vs 16.0%) while in I. ricinus the respective percentage was 29.6% and 30.55%. However, in subsequent years of the study the proportions between nymphs and females varied greatly in both species.

Abstract This chapter discusses the impact of climate change on the abundance and distribution of babesiosis vectors and, by implication, transmission of Babesia spp. It discusses evidence for climate change impact on the vectors Ixodes ricinus, Dermacentor reticulatus, Haemaphysalis punctata and Hyalomma spp. as well as the absence of evidence of the same climate change effects on the vectors Rhipicephalus spp. and I. scapularis.

Intraurban Near-Water Areas and Their Role in Distribution of Ticks (Acari, Ixodidae) in Megapolis the Example of Kyiv In 2002-2009, we studied 12 islands within the city of Kyiv, and found four indigenous species of ticks (Dermacentor reticulatus Fabricius, 1794; Ixodes ricinus Linnaeus, 1758; I. apronophorus Schulze, 1924; Rhipicephalus rossicus Jakimov et Kohl-Jakimova, 1911) and one invasive species (Hyalomma marginatum Koch, 1844). For A-E-gradient, established by man's impact degree, we revealed atypical distribution of species: their majority is noted in two pole areas - where the man impact is maximum and minimum. The investigated near-water areas are a kind of survival areas and sources of ixodides diversity in megalopolis.

Работа посвящена изучению динамики репродукции и фенотипических изменений вирусной популяции вируса клещевого энцефалита (ВКЭ) при долгосрочной инфекции, питании иксодовых клещей и при разных температурных условиях. Было показано, что температура окружающей среды оказывает существенное влияние на уровень репродукции ВКЭ в голодных иксодовых клещах. Однако при питании клещей происходит достоверно более быстрая и интенсивная репродукция ВКЭ по сравнению с зараженными клещами, содержащимися при повышенной (32-37 °С) и комнатной температурах. Штаммы ВКЭ европейского и сибирского подтипа успешно размножались и на протяжении длительного периода сохранялись в клещах, являющихся как основными (Ixodes ricinus, I. persulcatus), так и второстепенными (Dermacentor reticulatus) переносчиками вируса. Наибольших титров штамм сибирского подтипа достигал в клещах D. reticulatus, а штамм европейского подтипа - в клещах Ixodes ricinus и D. reticulatus. Длительная репродукция ВКЭ европейского и сибирского подтипов в организме клещей, являющихся основными и второстепенными переносчиками, повышала гетерогенность вирусной популяции, однако варианты вируса сохраняли высокую нейроинвазивность, характерную для вируса, адаптированного к клеткам ЦНС мыши. Штаммы ВКЭ разных подтипов различались по фенотипической гетерогенности популяции в разных условиях. В отличие от штамма Абсеттаров (европейский подтип) на гетерогенность вирусной популяции штамма ЭК-328 (сибирский подтип) по фенотипу бляшек на культуре клеток СПЭВ значительно повлияло питание клещей D. reticulatus после долгосрочной репродукции в них вируса.
