[ 1 ] - Molecular Detection of Novel Genetic Variants Associated to Anaplasma ovis among Dromedary Camels in Iran
To the best of our knowledge, little information is available regarding the presence of Anaplasma species in camels in Iran. This study sought to investigate the presence of Anaplasma species by microscopy and polymerase chain reaction (PCR) assays in 100 healthy dromedaries (Camelus dromedarius) arriving for slaughter. The microscopic examination of Giemsa-stained blood films revealed that Ana...
[ 2 ] - Abundance, diversity and seasonal dynamics of hard ticks infesting cattle in Isfahan province, central Iran
The objectives of this study were to determine the diversity, seasonal dynamics and abundance of ticks infesting cattle in Isfahan zone, Iran. The study was conducted in three traditional cattle farms. No acaricides had been applied to cattle at the selected farms. Adult ticks were collected twice per month from different parts of the cattle's body. Environmental data, including relative humidi...
[ 3 ] - Concentration of serum total iodine and thyroid hormones in Holstein cows in central Iran
The aim of this study was to evaluate total iodine, triiodothyronine (T3) and thyroxine (T4) status in the blood serum of Holstein cows on six farms in central Iran. Total iodine, T3 and T4 concentrations were measured in 90 blood serum samples (15 per farm). Mean concentrations of total iodine (38.80 ± 1.52 µg/l) and T3 (1.57 ± 0.10 nmol/l) were lower but the mean concentration of T4 (45.60 ± ...
[ 4 ] - Molecular study on infection rates of Anaplasma ovis and Anaplasma marginale in sheep and cattle in West-Azerbaijan province, Iran
This study was carried out to determine the presence and frequency of Anaplasma ovis and Anaplasma marginale in sheep and dairy cattle in West-Azerbaijan province, Iran. A total number of 200 blood samples were randomly collected via the jugular vein from apparently healthy cattle (100) and sheep (100). The extracted DNA from blood cells was screened using genus-specific (Anaplasma...
[ 5 ] - Molecular Detection of Anaplasma bovis in Cattle from Central Part of Iran
Anaplasma bovis is a leukocytotropic agent of bovine anaplasmosis and there is no available information about molecular study on this agent in cattle of Iran. In this study a total 150 cattle blood samples were collected from central part of Iran. The presence of A. bovis examined using light microscopic detection and species-specific nested polymerase chain reaction (nested-PCR) based on 16S r...
[ 6 ] - مقایسه و ارزیابی میزان مس، روی و آهن درسرم و جیره گاوهای هلشتاین شیری صنعتی و نیمه صنعتی در دو فصل گرم و سرد سال
خلاصه این مطالعه جهت ارزیابی وضعیت عناصر مس، روی و آهن در گاوداری های شیری صنعتی (12 گاوداری) و نیمه صنعتی (12 گاوداری) شهر اصفهان انجام شد. طرح به صورت بلوک کاملاً تصادفی با تکرار واحد آزمایشی با آزمون فاکتوریل انجام گرفت و مناطق جغرافیایی (شمال، جنوب، شرق، غرب) به عنوان بلوک در نظر گرفته شدند. تأثیرعوامل فصل در دو سطح (گرم و سرد) و نحوه پرورش در دو سطح (صنعتی و نیمه صنعتی) بر روی غلظت سرمی عنا...
[ 7 ] - تشخیص آناپلاسما اوویس بر اساس ژن 16S rRNA با روش PCR-RFLPدر گوسفندان قسمت مرکزی ایران
خلاصه: واکنش زنجیره ای پلیمراز یکی از اختصاصی ترین روش های تشخیص تفریقی گونه های آناپلاسما می باشد . واکنش زنجیره ای پلیمراز بر اساس ژن 16S rRNA می تواند گونه های جنس آناپلاسما را از یکدیگر تفریق نماید ولی توالی نوکلئوتیدی ژن 16S rRNA در آناپلاسما اوویس بسیار شبیه به آناپلاسما مارجیناله می باشد(9/99%تا 2/99%) و طراحی آغازگرهای اختصاصی برای تکثیر این دو گونه غیر ممکن است. گوسفند و بز می توا...
[ 8 ] - Molecular Detection of Bovine Leukocytic Anaplasma Species in Isfahan, Iran
Background: A. bovis and A. phagocytophilium are leukocytotropic agents of bovine anaplasmosis. They are obligate intracellular bacteria that can infect and cause Anaplasmosis in human and animals. Therefore, this study was carried out to detect A. bovis and A. phagocytophilum in naturally infected dairy cattle in Isfahan using molecular techniques. Materials and Methods: In this study a tot...
[ 9 ] - A review on Anaplasma phagocytophilum as a zoonotic agent: review article
Anaplasma phagocytophilum is a gram-negative intracellular bacterium that transmitted by hard ticks. A. phagocytophilum infect and multiply in the organs of ticks, in particular the salivary glands which enable the transmission to vertebrate hosts during feeding. The tick becomes infected by feeding on an infected host and there is transstadial but not transovarial passage of the organism. The ...
