Zoonotic tick-borne diseases are an increasing health burden in Europe and there is speculation that this is partly due to climate change affecting vector biology and disease transmission. Data on the vector tick Ixodes ricinus suggest that an extension of its northern and altitude range has been accompanied by an increased prevalence of tick-borne encephalitis. Climate change may also be partl...
Tick-borne diseases represent major public and animal health issues worldwide. Ixodes ricinus, primarily associated with deciduous and mixed forests, is the principal vector of causative agents of viral, bacterial, and protozoan zoonotic diseases in Europe. Recently, abundant tick populations have been observed in European urban green areas, which are of public health relevance due to the expos...
a 30-year-old african woman in kenya succumbed to severe swollen regional lymph nodes, development of painful boils and ulcer formation and rashes at specific tick-biting sites together with an intermittent fever and headache following repeated tick bites of rhipicephalus pulchellus. she later developed nuchal lymphadenopathy-like condition and an eschar with edematous margins at bitten sites. ...
We assessed the risk for human tick-borne encephalitis (TBE), ixodid tick-borne borrelioses, and double infection from 1994 to 1998 in Perm, which has among the highest rates of reported cases in Russia. We studied 3,473 unfed adult Ixodes persulcatus ticks collected from vegetation in natural foci and 62,816 ticks removed from humans. TBE virus and Borrelia may coexist in ticks.
Rhode Island is a state with a high incidence of tick-borne diseases, specifically Lyme disease. The Ioxedes tick which serves as vector for the three most common tick infections is endemic in both the New England and mid-Atlantic regions. However, differences in the density of infections exist within Rhode Island (RI), with the highest densities in the southern counties. Tick-borne diseases ca...
Human activities predominate in determining changing incidence of tick-borne encephalitis in Europe.
Explanations for the dynamics of tick-borne disease systems usually focus on changes in the transmission potential in natural enzootic cycles. These are undoubtedly important, but recent analyses reveal that they may not be quantitatively the most significant side of the interaction between infected ticks and humans. Variation in human activities that may impact inadvertently but positively on ...
Ticks and the pathogens they transmit constitute a growing burden for human and animal health worldwide. Vector competence is a component of vectorial capacity and depends on genetic determinants affecting the ability of a vector to transmit a pathogen. These determinants affect traits such as tick-host-pathogen and susceptibility to pathogen infection. Therefore, the elucidation of the mechani...
A number of tick-borne diseases of humans have increased in incidence and geographic range over the past few decades, and there is concern that they will pose an even greater threat to public health in future. Although global warming is often cited as the underlying mechanism favoring the spread of tick-borne diseases, climate is just one of many factors that determine which tick species are fo...
“The biology and ecology of ticks shape the potential for the transmission of zoonotic pathogens” is a collection of research and review articles related to the study of tick-borne diseases, with a focus on the methodology to explore the basic relationships between the tick-transmitted pathogens and the environment. It is well-known that a multidisciplinary point of view is necessary in order t...
