A total of 97 blood samples of nyala (Tragelaphus angasii, Gray 1849) from South Africa were tested for the presence of tick-borne haemoparasites by means of polymerase chain reaction (PCR) and reverse line blot (RLB) hybridization. The majority of blood samples contained several different haemoparasites, often in combination. Prevalent haemoparasites were Theileria sp. (kudu), T. buffeli, Thei...
We sequenced the genome of Theileria orientalis, a tick-borne apicomplexan protozoan parasite of cattle. The focus of this study was a comparative genome analysis of T. orientalis relative to other highly pathogenic Theileria species, T. parva and T. annulata. T. parva and T. annulata induce transformation of infected cells of lymphocyte or macrophage/monocyte lineages; in contrast, T. oriental...
سابقه و هدف: تیلریا لستوکاردی (theileria lestoquardi) از مهم ترین عوامل تیلریوز بدخیم در گوسفند و بز است که توسط کنه های سخت به میزبان نهایی منتقل می گردد. این تک یاخته تنها یوکاریوتی است که قادر به ترانسفورم کردن سلول میزبان می باشد. این پژوهش، با هدف تهیه استابلیت حاوی اسپروزوایت تیلریا لستوکاردی و استفاده از آن برای تولید رده سلولی حاوی شایزونت تیلریا لستوکاردی در شرایط آزمایشگاهی انجام شد. ...
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...
تیلریوزیس، بیماری انگلی ناشی از تک‌یاخته‌ی درون سلولی گونه‌های تیلریا است که توسط کنه‌های ایکسودیده منتقل می‌شود. شناسایی کنه‌های ناقل در هر منطقه برای ایجاد برنامه‌های منسجم پیش‌گیری علیه این بیماری، ضروری است. بر این اساس، از فروردین تا مرداد 1391 تعداد 219 کنه از سطح بدن 150 رأس گوسفند با سابقه‌ی تب و کم‌خونی از نقاط مختلف استان لرستان جمع‌آوری شد، در ضمن از خون محیطی این گوسف...
The prevalence of Theileria spp. infection was studied in sheep in the South Khorasan province in Iran from 2003 to 2004. A total of 840 sheep from 34 flocks were clinically examined and investigated for the presence of Theileria spp. in the appropriate blood smears and any tick species on the body of the animals. In this study, 11.9% of sheep were infected with Theileria spp., with a parasitem...
BACKGROUND A huge effort in rhinoceros conservation has focused on poaching and habitat loss as factors leading to the dramatic declines in the endangered eastern black rhinoceros (Diceros bicornis michaeli) and the southern white rhinoceros (Ceratotherium simum simum). Nevertheless, the role disease and parasite infections play in the mortality of protected populations has largely received lim...
Apicomplexan parasites of the genera Theileria and Plasmodium have complicated life cycles including infection of a vertebrate intermediate host and an arthropod definitive host. As the Plasmodium parasite progresses through its life cycle, it enters a number of different cell types, both in its mammalian and mosquito hosts. The fate of these cells varies greatly, as do the parasite and host mo...
Theileria parasites invade and transform bovine leukocytes causing either East Coast fever (T. parva), or tropical theileriosis (T. annulata). Susceptible animals usually die within weeks of infection, but indigenous infected cattle show markedly reduced pathology, suggesting that host genetic factors may cause disease susceptibility. Attenuated live vaccines are widely used to control tropical...
The intracellular parasite Theileria is the only eukaryote known to transform its mammalian host cells. We investigated the host mechanisms involved in parasite-induced transformation phenotypes. Tumour progression is a multistep process, yet 'oncogene addiction' implies that cancer cell growth and survival can be impaired by inactivating a single gene, offering a rationale for targeted molecul...
