کلونینگ و سکانس ژن hao3 کنه hyalomma anatolicum anatolicum در شاتل وکتور غیر ترشحی ppiczb

کنه هیالوما آناتولیکوم آناتولیکوم انگل خارجی حیوانات اهل و وحشی در مناطق گرم و نیمه گرم از جمله مناطق جنوب ایران است. این کنه ناقل بسیاری از بیماریهاست همچنین این انگل موجب کاهش تولید شیر و گوشت و پایین آمدن کیفیت چرم تولیدی حیوان میزبان می گردد. پروتئین hao3 کاندیدای تولید واکسن جهت ایجاد ایمنی در مقابل این کنه است لذا دراین تحقیق با استفاده از دو پرایمر اختصاصی orf ژن ha03 با استفاده از تک...

Immunization of cattle against Hyalomma anatolicum anatolicum using larval antigens.

Development of immunity in cross-bred (Bos taurus x Bos indicus) calves against Hyalomma anatolicum anatolicum, vector of bovine tropical theileriosis, was studied using larval antigen (LS) in Freund's complete adjuvant (FCA). Calves immunized with LS + FCA showed significant rejection of larvae (57.25 +/- 6.8) and nymphs (45.75 +/- 5.16). Abnormally fed larvae (11.4 +/- 0.8) and nymphs (8.25 +...

Natural infection rates and transmission of Theileria annulata by Hyalomma anatolicum anatolicum ticks in the Sudan.

Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6% of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e....

High infection rates of the tick Hyalomma anatolicum anatolicum with Trypanosoma theileri.

A crossbred calf (3 months old) obtained from a farm where regular control of ticks was practised and found to be free of blood parasites was inoculated with 20 ml pooled blood collected from four field cattle which had very low Trypanosoma theileri parasitaemias (one parasite per 70 microl blood as determined by the haematocrit centrifugation technique). Trypanosoma theileri was present in the...

Comparative immunopotentiating properties of saponin and incomplete Freund's adjuvant coupled to affinity purified larval antigen of Hyalomma anatolicum anatolicum.

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 ...
