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...

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...

BACKGROUND Our study aimed to assess the presence of different pathogens in ticks collected in two regions in Côte d'Ivoire. METHODOLOGY/PRINCIPAL FINDINGS Real-time PCR and standard PCR assays coupled to sequencing were used. Three hundred and seventy eight (378) ticks (170 Amblyomma variegatum, 161 Rhipicepalus microplus, 3 Rhipicephalus senegalensis, 27 Hyalomma truncatum, 16 Hyalomma marg...

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...

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...

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. ...

Aim This study was conducted in dairy cattle in Nyala, South Darfur State, during the period from June to September 2015, to study the prevalence of bovine tropical theileriosis. Materials and Methods Apparently, healthy cattle of different age groups, different breeds, and from both sexes were randomly selected from seven locations. Three age groups of cattle were selected, group one <1 year...

Hyalomma ticks were collected from Merino and black-headed Dorper sheep and their attachment preferences determined. The preferred site of attachment for Hyalomma marginatum rufipes on both Dorper and Merino sheep was the anogenital and inguinal areas (75-76%). On Dorper sheep, H. truncatum attached predominantly to the anogenital and inguinal areas (67.7%). On Merino sheep, most adults of this...
