Abstract:

Arthropod-borne viruses, arboviruses, have the ability to replicate in both vertebrates and invertebrates and are transmitted to susceptible vertebrate hosts by vectors such as mosquitoes and ticks. Ticks are important vectors of many highly pathogenic arboviruses, including the flavivirus tick-borne encephalitis virus (TBEV) and the nairovirus Crimean-Congo haemorrhagic fever virus. In contrast, alphaviruses are principally mosquito-borne and have been isolated only rarely from ticks; ticks have not been implicated as their vectors. Nevertheless, the alphavirus Semliki Forest virus (SFV) repl

Vector-borne diseases are an increasing global threat to humans due to climate changes, elevating the risk of infections transmitted by mosquitos, ticks, and other arthropod vectors. Ixodes ricinus, a common tick in Europe, transmits dangerous tick-borne pathogens to humans. Tick-borne encephalitis (TBE) is a vector-borne disease caused by TBE virus (TBEV). Climate change has contributed to increased tick abundance and incidence of tick-borne diseases, and between 10,000 and 15,000 human TBE cases are reported annually in Europe and Asia.

Powassan (POW) virus, the cause of human encephalitis in the northeastern U.S. and Canada, is transmitted by tick bite. Since the geographic and host distribution patterns of Ixodes dammini Spielman, et al, 1979 and POW virus overlap, the potential of this tick species to transmit POW virus was explored. Transmission experiments were conducted with hamsters and rabbits which fed immature and adult ticks, respectively, from a POW-free colony. Oral infection rates in larvae and nymphs fed on POW-infected hamsters were 10% and 40%, respectively; in females fed on POW-infected rabbits, 57%. Transs

Abstract:

Globally, vector borne diseases cause more than a million deaths each year and more than a billion infections in humans. Ticks are of big medicinal importance since they can transmit pathogens that can cause serious infections. Some recently discovered pathogens that can cause infections in humans are Anaplasma phagocytophilum (A. phagocytophilum) that can cause human granulocytic anaplasmosis (HGA) and Candidatus Neoehrlichia mikurensis (N. mikurensis) that can cause Neoehrlichiosis. It is still widely unknown how prevalent these pathogens are, if ticks can be infected with both of these path

Abstract:

Parasites often have profound effects on the survival and evolution of their hosts, and hence on the structure and health of entire ecosystems. Yet basic questions, such as the degree of virulence of a given parasite on its host, and factors influencing which hosts in a population are at the greatest risk of infection, are vexingly difficult to resolve. The western blacklegged tick-western fence lizard (Ixodes pacificus-Sceloporus occidentalis) system is important, primarily because I. pacificus, a vector of the Lyme disease spirochete Borrelia burgdorferi, is dependent on S. occidentalis for

Abstract:

The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. This has been contradicted by recent analyses estimating that the tick-borne flaviviruses emerged at least before 16,000 years ago. It has also been argued that the Powassan virus was introduced into North America at the time between the opening and splitting of the Beringian land bridge. Su

The purpose of this study was to determine the prevalence of Lyme Disease (LD) bacteria in adult Ixodes pacificus ticks collected from the mountains of San Bernardino County in Southern California. Seven hundred fifty four I. pacificus adults were collected from the Pacific Crest Trail and adjacent areas. The Polymerase Chain Reaction (PCR) was used to screen ticks for Borrelia burgdorferi infection by targeting two different DNA loci. Oligonucleotide primers targeting both the ospA and fla genes were used in the assay. Ticks were processed in pools of three, and genomic DNA from the ticks was

Ticks are of global interest as the pathogens they spread can cause diseases that are of importance to both human health and economies. In Scotland, the most populous tick species is the sheep tick Ixodes ricinus, which is the vector of pathogens causing diseases such as Lyme borreliosis and Louping-ill. Recently, both the density and spread of I. ricinus ticks have grown across much of Europe, including Scotland, increasing disease risk. Due to the nature of the tick lifecycle they are particularly dependent on environmental factors, including temperature and habitat type. Because of this, th

Originally confined to New England, it has since spread across much of the east coast and has become endemic in Virginia. Since 2010 the state has averaged 1200 cases per year, with 200 annually in the New River Health District (NRHD), the location of our study.

Abstract:

Le degré de spécialisation d'hôte des parasites peut considérablement modifier la nature des interactions interspécifiques. Lorsque les parasites sont également vecteurs, leur capacité d'adaptation et leur réponse aux changements dans la communauté d'hôtes aura des conséquences importantes sur la dynamique de leurs populations, mais aussi sur les microparasites qu'ils transmettent. Une première étape pour mieux appréhender l'importance de ce phénomène sur l'écologie et l'évolution des systèmes vectoriels est d'étudier la divergence génétique associée à l'hôte. Nous avons utilisé cette approche

Abstract:

Lyme borreliosis (LB) is the most frequent vectorborne disease in the Northern Hemisphere. It is a complex bacterial zoonosis involving vertebrate hosts and hard ticks of the genus Ixodes. The causative agents, bacteria of the LB group of spirochaetes, form a species complex comprising 17 named species. As is the case for most microbial pathogens, epidemiological and ecological studies require appropriate genotyping. Although the use of single loci may provide rapid results, there are serious disadvantages, in particular when inferring evolutionary relationships or geographic population struct

Abstract:

In Indiana, Ixodes scapularis is an important tick in public health because it feeds on a variety of hosts including humans, and transmits Borrelia burgdorferi (Lyme disease), Anaplasma phagocytophilum (human granulocytic ehrlichiosis), and Babesia microti (babesiosis). Symbiotic, non-pathogenic Rickettsia found in Ixodes scapularis may play a role in excluding pathogenic species of Rickettsia from being transovarially transmitted. In order to investigate this idea further in Indiana, a total of 378 adult I. scapularis from 4 different counties (Jasper, Pulaski, Newton and Starke) were tested

Abstract:

The Lyme disease causing spirochaete Borrelia burgdorferi sensu lato is transmitted by ticks within the genus Ixodes. These ticks are liberal host seekers and parasitise mammals, birds and reptiles. Prior to this study, the distribution of I. ricinus ticks and Lyme disease was thought to be restricted to the southern half of Sweden. On the island Norrbyskär, located in the Bothnian Gulf, there were reports of a high incidence of tick infestation on humans. To investigate the occurrence of B. burgdorferi s.l. in these ticks and to characterise presumptive isolates at the molecular level we samp
