TL;DR: It was established that considerable interchange between autumn-feeding and spring-feeding populations of ticks can occur, and it was concluded that the extent of this is largely controlled by the weather, being accentuated by high summer temperatures.
Abstract: Development rates of engorged examples of Ixodes ricinus (L.) and the onset and duration of questing activity of unfed ticks were investigated in gauze cages in the field in the Irish Republic. Development rates of the various stages were broadly similar to those described in other studies but differed in small detail from most of them. It was found that larvae that fed during or after the first two weeks of August entered diapause. The activity periods of questing ticks were found to agree closely with observations made in the field, and the origins of the various peaks in tick activity in the field were thus elucidated. It was established that considerable interchange between autumn-feeding and spring-feeding populations of ticks can occur, and it is concluded that the extent of this is largely controlled by the weather, being accentuated by high summer temperatures.

TL;DR: This method was used to sample larval tick populations on ten farms with endemic babesiosis and it was found that these farms harboured very low densities of ticks compared with a control site.
Abstract: SUMMARY
Tick sampling methods based on blanket dragging and flagging were assessed with a view to carrying out a tick survey in an area of endemic babesiosis. The strip-flag method was finally selected for its efficiency, consistency, and practicality.
This method was used to sample larval tick populations on ten farms with endemic babesiosis and it was found that these farms harboured very low densities of ticks compared with a control site. Possible explanations for this finding are discussed.

TL;DR: The results presented in this study are based on observations made during some 10 years in the French Alps and their surroundings and particular attention is drawn to the appearance of new, and the extension of previously known foci of disease transmission in the vicinity of large cities.

TL;DR: This case presented as a fluctuating meningoencephalitis with superimposed cranial neuropathy, and the characteristic skin lesion, erythema chronicum migrans, was recognized by history, and oligoarticular arthritis subsequently developed.

TL;DR: Dunesheep are the main hosts for the tick Haemaphysalis punctata on the island of Texel and additional hosts include horses, native mammals (rabbit, ferret) and a number of bird species (especially for the larvae and nymphs).
Abstract: Dunesheep are the main hosts for the tick Haemaphysalis punctata on the island of Texel. Ali stages may complete their bloodmeal on these animais. Additional hosts include horses, native mammals (rabbit, ferret) and a number of bird species (especially for the larvae and nymphs). The dependance of this tick on dunesheep appears to originate from the absence of big game on the island and the fact that only sheep are pastured to any extent in the dunes. This also means that only about 3-4 % of the area of the island is infested with this tick. Ixodes ricinus is present on the island also: adults on sheep, dogs and cats; nymphs on sheep, rab bits and a few bird species; larvae on rab bits, mice and birds. This tick is Jess common but occurs on a larger area. lt is not restricted to the dry sheep-grazed dune area, but also present in woods and bushes. H. punctata is known from a number of other Frisian islands but appears to be absent from the mainland of the Netherlands
