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...
Pollen is one of the primary causes of allergic rhinoconjunctivitis in urban centers. In the present study, the concentrations of 39 different pollens in the Santiago de Chile metropolitan area over the period 2009-2013 are characterized. The pollen was monitored daily using Burkard volumetric equipment. The contribution of each type of pollen and the corresponding time trends are evaluated. Th...
increasing energy demands associated with economic growth and industrialization have resulted in dramatic increases in air pollution emissions. air pollution damages the plant mainly by disrupting cell homeostatic conditions.in the present study, diverse plant criteria indicating air pollution from different levels including cell biochemistry, leaf and tree crown in the plane-tree were determin...
Bunias orientalis and Erigeron annuus are two alien herbal plant species invading native ecosystems in Lithuania. Both species have similar introduction and invasion history but differ in their life history traits and strategies of reproduction. We used random amplified polymorphic DNA (RAPD) data to compare the genetic diversity in invasive populations of these species. 42 RAPD bands were iden...
Visceral leishmaniasis (VL) is one of the major public health problems in northwest Ethiopia, mainly in Libo-Kemkem and Metema districts, where Phlebotomus orientalis is the most probable vector of the disease. The aim of this study was to determine the physiological age, host preference and vectorial potential of P. orientalis in the highland and lowland foci of the region. Sand flies were col...
BACKGROUND Certain salivary proteins of phlebotomine sand flies injected into the host skin during blood-feeding are highly antigenic and elicit strong antibody-mediated immune responses in repeatedly-exposed hosts. These antibodies can be measured by enzyme-linked immuno sorbent assays (ELISAs) using salivary gland homogenates (SGHs) as the source of antigens and serve as a markers for exposur...
Loop-mediated isothermal amplification (LAMP) is a rapid method with high specificity and efficiency under isothermal condition using a set of four specifically designed primers that recognize six distinct sequences on the target gene. In this study, a LAMP method was developed for specific detection of Babesia orientalis in water buffalo (Bubalus babalis, Linnaeus, 1758). Four primers were des...
The C-banding karyotype of the jerboas Allactaga tetradactyla, Jaculus jaculus jaculus, and Jaculus orientalis was described and interspecific relationships were discussed. Despite the conservation of a relatively small amount of C-heterochromatin located at the centromeric region of some chromosomes in all karyotypes, a striking loss of C-heterochromatin was clearly observed in J. orientalis. ...
درخت چنار یکی از درختان مهم در فضای سبز شهر تهران است که در سال‌های اخیر تحت تاثیر آلودگی شدید هوای تهران دچار خزان زود هنگام شده است. در پژوهش حاضر به‌منظور مشخص شدن علت این پدیده صفاتی نظیر سطح برگ وزن خشک، هدایت روزنه، مقاومت روزنه، رطوبت نسبی برگ، غلظت نسبی کلروفیل، مقادیر عناصر کلسیم، منیزیوم، سرب و کادمیوم مورد سنجش قرار گرفت. برگ درختان چنار در اواخر بهار از سه منطقه شهر تهران با مقادیر ...
