Five species of ixodid ticks were found in a cross-sectional survey in which 200 sheep were examined for ticks in River Nile Province, Sudan. Hyalomma anatolicum anatolicum was the predominant species (73.6%), whereas ticks belonging to the Rhipicephalus sanguineus group (14.7%), Rhipicephalus evertsi evertsi (9.1%), Rhipicephalus simus (2%) and Hyalomma dromedarii (0.5%) were also found. The m...

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...

Monthly total body tick collections from 13-20 camels were conducted for 2 consecutive years (2000-2001) in Northern Sudan. Tick populations were correlated with locality, season, predeliction site, sex and coat colour. Hyalomma dromedarii was found to be the predominant (89%) tick species infesting the camels. Other tick species found in very low numbers were Hyalomma impeltatum (7.7%), Hyalom...

background: taxonomy and identification of the ticks in the genus hyalomma, the most significant vectors of animal and human pathogen agents, have always been debatable. scientists believe that variation within the taxa of the genus hyalomma is the most important factor which causes misidentification. objectives: the purpose of this study is to identify valuable characters for male h. anatolicu...

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...

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...

Comparative immunostimulatory properties of saponin and incomplete Freund's adjuvant (IFA) were studied using affinity purified 39 kDa larval antigen of Hyalomma anatolicum anatolicum. Significant antibody response to 39 kDa antigen was detected in the sera of rabbits immunized with both 39 kDa plus saponin and 39 kDa plus IFA in comparison to their corresponding control animals. Insignificant ...

partially fed (4 -5 days) h .a. anatolicum (iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (gs), gut membrane antigen (gm), triton extracted gut membrane antigen ( tx-gm ) and sodium dodecyl sulphate treated triton extracted gut membrane antigen (sds-tx-gm). the new zealand white rabbits were immunized with gs, gm, tx- gm...
