samples were collected from soil and as well from phyllosphere of rice plant and subjected to dilution plate technique on rbsf trichoderma selective medium. a total of 202 trichoderma isolates were obtained from rice fields at different geographical locations distributed all over mazandaran province. single spore isolates were obtained and genomic dna extracted from all the isolates using dna e...
Abstract DNA sequencing is one of the great valuable techniques in molecular biology, which can be used to detect the sequence of nucleotides in a DNA fragment. The high-throughput sequencing known as Next Generation Sequencing (NGS) revolutionized genomic research and molecular biology; therefore, the whole human genome can be sequenced with a low cost in several days. NGS technology is simi...
Drought stress is one of the most limiting abiotic stresses affecting growth, production and survival of plants in many areas of the world, and is expected to intensify considering the trend of climate change. Grass species are important for the sustainability of agricultural systems, forage resources for animal farming and landscapes. Grass species adapt to water deficit by different morpholog...
background: toxocara is a common nematode of cats in different parts of iran. despite the close association of cats with human, no attempt has been done so far for molecular identification of this nematode in the country. therefore, current study was performed on identification of some isolates of toxocara from stray cats in shiraz, fars province, southern iran, based on morphological and molec...
background: species of microsporidia have been known as opportunistic obli-gate intracellular parasites particularly in immunocompromised patients. enterocyto-zoon bieneusi is one of most prevalent intestinal microsporida parasites in hiv + /aids patients. in this study, intestinal microsporidia infection was deter-mined in hiv + /aids patients using microscopic and molecular methods. methods: ...
background : cryptosporidium is an intracellular apicomplexan parasite that infects a wide range of vertebrates including humans. cryptosporidiosis is a major cause of diarrhea in children with and without human immunodeficiency virus (hiv) infection in developing countries. more recently, the molecular methods for identification of morphologically indistinguishable species have been developed...
aphids are among important agricultural pests. the pest's evolutionary tendency towards a loss of taxonomically useful characteristics, as well as morphological plasticity due to host type and as a result of environmental factors, make a morphological identification of aphids difficult, whereas exact identification is indispensable for managment of these pests. thus, modern identification ...
Detection, identification and measurement of microbial pathogens is critical for protecting public health. Although microbial culture-based tests and molecular techniques are currently the most commonly used, these techniques are time-consuming and require complex tools and experienced individuals. Consequently, it is costly to analyze these techniques. The emergence of the aptamer led to the e...
background: due to the predisposing conditions in patients with cystic fibrosis (cf) caused by defective mucociliary clearance facilitating colonization and invasion with candida species has dramatically increased. traditional methods for identifying problems are imminent and time-consuming. therefore, molecular techniques utilizing amplification of target dna provide quick and precise methods ...
Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...
