background: ticks are the most important vectors whichtransmit several arthropod-borne diseases such as theileriosis,babesiosis, and anaplasmosis. objectives: an epidemiologicalstudy was conducted in semnan area to determine thecurrent situation of tick infestation in sheep and assess theefficacy of usage of cis-cypermethrin against tick infestationunder field condition. methodes: sampling was ...

Of 263 patients in Tuscany, Italy, from whom ticks were removed during July 2005-May 2007, five showed signs of tick-borne encephalopathy. Of the ticks, 17 were Dermacentor marginatus; 6 (35.3%) of these were identified by sequence analysis as containing Rickettsia slovaca. Tick-borne lympadenopathy occurs in this area.

To the Editor: Dermacentor spp. ticks are found in many countries in Europe, and are vectors for several pathogens, including Francisella tularensis, Coxiella burnetii, Rickettsia spp., and Babesia canis (1,2). Because Dermacentor marginatus ticks require warm dry habitats, these ticks are found in only a few areas in southern Germany, mainly in the Rhine and Main valleys (3). However, these ti...

A total of 370 ticks, encompassing 7 species from 4 genera, were collected during 2002-2006 from domestic animals and vegetation in the Taza region of northeastern Morocco. Rickettsial DNA was identified in 101 ticks (27%) by sequencing PCR products of fragments of the citrate synthase and outer membrane protein genes of Rickettsia spp. Seven rickettsiae of the spotted fever group were identifi...

This study describes the epidemiological, clinical, and microbiological characteristics of a new tick-borne disease in Spain-Dermacentor-borne necrosis erythema lymphadenopathy (DEBONEL). The clinical presentations include an eschar at the site of the tick bite, surrounded by an erythema and painful regional lymphadenopathy. The disease appears during the colder months and its vector is Dermace...
