Gynandromorphic ticks are extremely rare, and often attract parasitologists' attention. During our examination of tick specimens, an engorged gynandromorph of Hyalomma asiaticum was noticed. This is the first record of gynandromorphic ticks from China. In this study, several important morphological structures of normal and gynandromorphic H. asiaticum were analyzed. Comparing to the normal H. a...

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...

Hard ticks (Acari: Ixodidae) are important obligatory blood feeding external parasites of human and animals. There have been a lot of studies on taxonomy of Iranian ixodidae. On the basis of morphological features found basically in adult male. There are problems in tick identification due to their intraspecific variations and morphological changes of the surface body of ticks after blood feedi...

ompA: JF803906). All samples were cultured in human embryonic lung fibroblasts as described (6). After 4 weeks, no bacteria were isolated. We report a human case of R. eschlimannii infection in Crete, Greece. Our finding was confirmed by molecular methods. However, we were not able to cultivate R. aeschlimannii from samples collected. This result suggests that living microorganisms may have die...

ticks are an important problem among zoonotic diseases. main veterinary species of hard ticks are: hyalomma sp. boophilus sp and rhipicephalus sp. among them hyalomma sp. have widespread distribution in iran and middle east. the best method to control hyalomma sp. is immunological one, by using antigens, which causes immunologic and physiologic reactions in host.bm86 is one of the best antigens...

based on the consideration that R. aeschlimannii is usually found in ticks of the genus Hyalomma, primarily in H. marginatum (1). Therefore, 1 of the PCRs amplifi ed a fragment of the Hyalomma tick mitochondrial cytochrome oxidase I gene and the other a fragment of the internal transcribed spacer 2 (7). The ITS2 fragment displayed the highest (99%) similarity with the respective fragment of H. ...

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...

An outbreak of lameness amongst Merino lambs, associated with the presence of Hyalomma ticks, was investigated on a farm in the south-western Free State, South Africa. The purpose was to follow the progress of the condition and to determine the extent of involvement of the two Hyalomma species which occur in the region. The flock of experimental sheep (n = 460) ranged free in natural veld under...

Taxonomic uncertainty as to the identities of Hyalomma (Euhyalomma) scupense Schulze, 1919 and Hyalomma detritum Schulze, 1919 has existed for nearly 85 years. The chief criterion used to consider these taxa as separate species has been an ecological feature, namely that H. scupense is a one-host tick while H. detritum is a two-host species. Morphologically they are identical. To date no compre...
