Ultrastructure of spirochetes isolated from Ixodes ricinus and Ixodes dammini.
Two strains of Ixodes spirochetes, one isolated in the United States (B31) and the other in Sweden (G25), were examined by electron microscopy. Cells of strain G25 were 11-25 micron long with a wavelength of 2.1-2.4 micron and an amplitude of 0.4 micron. Eleven flagella were inserted subterminally at each end of the cell. Cells of strain B31 were similar but had eleven or seven flagella. Cytopl...
متن کاملEstimating Ixodes ricinus densities on the landscape scale
BACKGROUND The study describes the estimation of the spatial distribution of questing nymphal tick densities by investigating Ixodes ricinus in Southwest Germany as an example. The production of high-resolution maps of questing tick densities is an important key to quantify the risk of tick-borne diseases. Previous I. ricinus maps were based on quantitative as well as semi-quantitative categori...
متن کاملCleavage in Ixodes ricinus (L.) (Acari: Ixodidae).
The author analyzed the first 5 days of embryonic development of Ixodes ricinus. The cleavage takes 4 days, being terminated on the 5th day of embryogenesis, when the cells start to invaginate and differentiate. The karyomeres play a role in the initial mitotic divisions. Cellularization occurs on the 2nd and 3rd day of embryogenesis. The blastoderm cells maintain their potential for division, ...
متن کاملTransmission of Bartonella henselae by Ixodes ricinus
Bartonella spp. are facultative intracellular bacteria associated with several emerging diseases in humans and animals. B. henselae causes cat-scratch disease and is increasingly associated with several other syndromes, particularly ocular infections and endocarditis. Cats are the main reservoir for B. henselae and the bacteria are transmitted to cats by cat fleas. However, new potential vector...
متن کاملSeasonality of Ixodes ricinus and Ixodes trianguliceps tick on the bank vole (Myodes glareolus) and on vegetation in Central Finland
Many infectious diseases are zoonoses, that is, they can be transmitted between vertebrate animals and humans. More than a fifth of zoonotic pathogens are transferred from one host to another by vectors, which are often blood-sucking arthropods, such as ticks. In Europe, Lyme borreliosis, spread by Ixodes ricinus tick, is the most prevalent tick-borne zoonosis. I. ricinus spreads also other zoo...
