Thuja orientalis (CommonlyMorpankhi, FamilyCupressaceae) is an evergreen, monoecious trees or shrubs used in various forms of traditional medicines and homeopathy in various ways. In traditional practices Thuja is used for treatment of bronchial catarrh, enuresis, cystitis, psoriasis, uterine carcinomas, amenorrhea and rheumatism. Recent researches in different parts of the world have shown tha...
A new species of fire-bellied newt, Cynops fudingensis, is described from northeastern Fujian Province, southeastern China. This species forms a well-supported clade with C. orientalis and C. orphicus based on molecular phylogenetic analysis of nucleotide sequences from mitochondrial DNA subunit two of NADH dehydrogenase and its two flanking tRNAs. Further, its genetic distance to each of the t...
AIM The aim of the present study was to investigate the presence of Theileria in blood samples of crossbred and indigenous adult cows raised under unorganized small scale farming system in a Babesia and Anaplasma endemic geographical area from Assam, India and to see its transmission through Rhipicephalus (Boophilus) microplus ticks. MATERIALS AND METHODS For the present study, 57 clinical ca...
Niébé is a food leguminous plant cultivated in tropical Africa for its seeds rich in proteins. The main problem setted by its production is the conservation of harvests. In the fields as in the stocks, the seeds are destroyed by pests (bruchids). These bruchids are always associated with several entomophagous species of hymenoptera. Four entomophagous species were listed : an egg parasitoid (U ...
Tick-borne pathogens can cause serious problems in grazing cattle. However, little information is available on tick-mediated diseases in cattle grazing on mountains. Thus, this study aimed to understand the potential problems related to tick-borne diseases in grazing cattle through the investigation of prevalent tick-transmitted infections, and their associated hematological changes, in terms o...
Vaccine development against extracellular bacteria has been important for the sustainability of the aquaculture industry. In contrast, infections with intracellular pathogens remain largely an unresolved problem. Francisella noatunensis subsp. orientalis is a Gram-negative, facultative intracellular bacterium that causes the disease francisellosis in fish. Francisellosis is commonly characteriz...
Infections of a population of Crassostrea gigas by the copepod Mytilicola orientalis were examined at an oyster growing site at Dungarvan, County Waterford, Ireland. Twenty-one samples, each consisting of 20 to 30 oysters have been examined over 2 yr. Condition, sex, reproductive stage, length, weight, glycogen content and other parasite burdens of the oysters were examined in relation to the d...
این تحقیق با هدف مطالعه الگوی رشد و تکوین آنزیم آلفا آمیلاز در لارو ماهی سیم معمولی (abramis brama) از زمان تخمگشایی تا 60 روز پس از آن در مجتمع تکثیر و پرورش و بازسازی ذخایر شهید انصاری (گیلان، رشت) به اجرا درآمد. نتایج نشان داد که در زمان تخمگشایی لاروها دارای وزنتر اولیه 03/0 ± 65/0 میلیگرم و طول کل 24/0 ± 66/4 میلیمتر بودند. الگـوی رشد در ماهی سیـم معمولی درطی روند تکـوین اولـیه تا ...
Predictions of species responses to climate change often focus on distribution shifts, although responses can also include shifts in body sizes and population demographics. Here, shifts in the distributional ranges ('climate space'), body sizes (as maximum theoretical body sizes, L∞) and growth rates (as rate at which L∞ is reached, K) were predicted for five fishes of the Cyprinidae family in ...
Babesiosis is a globally important zoonotic disease caused by tick-borne intraerythrocytic protozoan of the genus Babesia (phylum apicomplexa). In China, there are five species that infect cattle buffalo and cause great economic loss, which include Babesia bigemina, B. bovis, B. major, B. ovata, and B. orientalis. Among them, B. orientalis is the most recently identified new Babesia species epi...
