Little is known about tick-borne diseases in Saudi Arabia, particularly regarding the prevalence of theileriosis in small ruminants. This survey studied the potential vectors of malignant theileriosis in Saudi Arabian sheep. Blood, lymph node and tick samples were collected from animals being treated or necropsied at the Veterinary Diagnostic Laboratory in Jeddah, Makkah (western region), and B...

A cross-sectional survey of ticks infesting sheep was conducted in Sennar State, Sudan. A total body collection of ticks was carried out at five localities Sennar town, Singa, Dinder, Abu Naama and Um Banein on two types of Desert sheep (Watish and Ashgar) on two farms at each locality at two monthly intervals for one year starting July 2002 to May 2003. Four tick genera and eight species were ...

The spatial pattern in Senegal of Crimean-Congo hemorrhagic fever (CCHF) virus IgG antibody prevalence in human and sheep was determined as was the relative abundance of potential tick vectors. A systematic, country-wide serological survey of sheep demonstrated that 10.4% of sheep exhibited IgG to CCHF virus. Sexes were infected equally. Antibody prevalence increased with age from 2.1% during t...

A method for the identification of three ixodid tick species; the cow tick (Boophilus annulatus), the camel tick (Hyalomma dromedarii) and the cattle tick (Hyalomma anatolicum excavatum) based on restriction enzyme analysis of the second internal transcribed spacer (ITS-2) in the nuclear ribosomal DNA was adopted. PCR products with MW 1375 bp, 1650 bp and 1835 bp from B. annulatus, H. dromedari...

A total of 48 springbok, 48 gemsbok, 23 kudus and 6 giraffes were examined for ticks and lice, while 9 Burchell's zebras and 6 Hartmann's mountain zebras were examined only for ticks. Springbok and gemsbok were shot in both the Etosha National Park in the north and the Hardap Nature Reserve in the south of Namibia. All the other animals were shot in the Etosha National Park. A total of 7 ixodid...

ticks are important acarina that infest animals. they are obligatory blood sucker arthropods which economically impact cattle industry by reducing weight gain and production. moreover, they are important vectors of viral, bacterial, rickettsial and parasitic pathogens infecting humans and animals. in view of the importance of hyalomma anatolicum anatolicum in pathogen transmission, including th...

Recent advances in climate research together with a better understanding of tick-pathogen interactions, the distribution of ticks and the diagnosis of tick-borne pathogens raise questions about the impact of environmental factors on tick abundance and spread and the prevalence and transmission of tick-borne pathogens. While undoubtedly climate plays a role in the changes in distribution and sea...
