To determine the tick species parasitizing domestic ruminants in Zabol, Zahak and Qaen Counties which are located in east of Iran and are bordered with Afghanistan country, about 73 sheep, 44 goats and 27 cattle of 12 herds in several villages in Zabol, Zahak and Qaen Counties were inspected for tick infestation. Separated ticks were preserved in 70% alcohol and identified. About 464 ticks (252...
The impact of climate trends during the period 1901-2009 on the life cycle of Hyalomma marginatum in Europe was modeled to assess changes in the physiological processes of this threat to public health. Monthly records of temperature and water vapour at a resolution of 0.5° and equations describing the life cycle processes of the tick were used. The climate in the target region affected the rate...
The development of Babesia occultans in the salivary glands of adult Hyalomma marginatum rufipes was studied with the electron microscope. Sporogony involved a process of multiple fission in which sporozoites formed from the periphery of a polymorphous sporont. Different stages of development were found concurrently in individual acini as well as within individual acinar cells. Mature sporozoit...
The development of Babesia caballi in the salivary glands of Hyalomma truncatum was studied at the electron microscopic level. Kinetes were first observed in the salivary glands of ticks on Day 2 of tick feeding and on each subsequent day of feeding until engorgement on Day 8. Sporogony appeared to involve the formation of cytomeres. After continued nuclear division, sporozoites formed when ind...
We report on the identification of two new Francisella-like endosymbionts (FLEs) found in three different tick species from Bulgaria. The FLEs were characterized by 16S rRNA and tul4 gene sequencing and seem to lack the molecular marker RD1. These two new taxa seem to be facultative secondary endosymbionts of ticks.
In the of period 2003-2007, a total of 382 specimens of reptiles belonging to the following genera were investigated: Testudo, Iguana, Varanus, Gongylophis, Python, Spalerosophis, Psammophis. The material for the present study was a collection of reptiles owned by the "Animals" Ltd from Swietochłowice (Upper Silesia, Poland), specialising in import of exotic animals to Poland, as well as the re...
SALIH, D.A., HASSAN, S.M., EL HUSSEIN, A.M. & JONGEJAN, F. 2004. Preliminary survey of ticks (Acari: Ixodidae) on cattle in northern Sudan. Onderstepoort Journal of Veterinary Research, 71: 319–326 In a cross sectional survey conducted during the period June 2001 to July 2002, the geographical distribution of ticks on cattle in the Sudan was determined. Seventeen locations were surveyed from No...
اهمیت دامپزشکی و پزشکی کنه های جنس هیالوما (.hyalomma spp) از نظر انتقال بیماری های مرتبط، امری بدیهی و ثابت شده است. کنه های این جنس از نظر تاکسونومی و تشخیص همواره مورد بحث بوده اند. گاهی اوقات تشخیص دقیق دو گونه نزدیک به هم hyalomma anatolicum و hyalomma asiaticum موجود در فون ایران از نظر مرفولوژیکی بسیار مشکل است. هدف از مطالعه حاضر بررسی و توصیف خصوصیات ظاهری اندام هالر (haller’s organ) ب...
BACKGROUND Mosquitoes are the primary vectors of West Nile virus (WNV). Ticks have, however, been suggested to be potential reservoirs of WNV. In order to investigate their role in the spread of the virus, ticks, which had been collected from birds migrating northwards from Africa to Europe, were analyzed for the potential presence of WNV-RNA. METHODS On the Mediterranean islands Capri and An...
Ticks are vectors and reservoirs of many arboviruses pathogenic for humans or domestic animals; in addition, during bloodfeeding they can acquire and harbour pathogenic arboviruses normally transmitted by other arthropods such as mosquitoes. Tick cell and organ cultures provide convenient tools for propagation and study of arboviruses, both tick-borne and insect-borne, enabling elucidation of v...
