in order to detect hydrogen cyanide gene and to determine pseudomonas fluorescent efficiency in producing hydrogen cyanide for controlling the growth of rhizoctonia solanipathogen (the causal agent of sugar beet root and crown rot), samples were collected from sugar beet rhizosphere in sabzevar fields. after soil sampling and purification, 31 pseudomonas spp. isolates were separated on specific...

Fusarium species are cosmopolitan species that frequently isolated from soils and plantdebris and can seriously damaged plant, animal and human. Persian Gulf beaches in Iranare the ideal habitat for a variety of Fusarium species. Therefore, the study is conductedto gather some information on the population of Fusarium species which could be foundin Persian Gulf beaches in Iran. The study involv...

BACKGROUND: Colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. OBJECTIVES: In order to evaluate molecular epidemiologyof some virulence associated factors in Escherichia coli,isolated from poultry, the presence of iut A, iss, hly F, omp T, iroN, afa, sfa (S)and pap G (II) were investigated by multiplex PCRassay. METHODS: Two hundred th...

BACKGROUND Fasciola hepatica and F. gigantica are the causative agents of fasciolosis in domestic animals and humans. Based on the morphometric criteria, differential diagnosis between them is problematic. In addition, intermediate forms of Fasciola have been found in Iran, which makes the differentiation more difficult. The aim of the present study was to provide molecular evidence for the exi...

The peptide-N4-(N-acetyl-beta-D-glucosaminyl) asparagine amidase F (PNGase F) gene from Flavobacterium meningosepticum was cloned into a high copy number Escherichia coli plasmid. Levels of PNGase F activity produced in cultures of the recombinant strain were up to 100-fold higher than those obtained in cultures of F. meningosepticum. The complete PNGase F gene sequence was determined. Comparis...

Fusarium graminearum is causal agent of economically catastrophic disease of cereal Fusarium Head Blight (FHB) around the world. In addition to causing a loss of yield, this fungus causes serious threats to humans and animals due to the contamination of grain with the trichothecene mycotoxin. TRI101 gene, a Fusarium spp. gene, encodes an enzyme that transfers an acetyl group to the C3 hydroxyl ...

OBJECTIVE The curative treatment approach for diffuse large B-cell lymphoma (DLBCL) is controversial even in the rituximab (R) era. The aim of this study was to examine the FcγRIIIA gene polymorphism distribution of DLBCL patients who had been treated with R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. Furthermore, we investigated the impact of FcγRIIIA gene p...

lactoferrin is a glycoprotein with molecular weight 80 kda iron-binding bond, which is composed of 690 amino acids. in most mammalian body fluids such as sweat, semen, tears, and saliva and milk neutrophil granules there. bovine lactoferrin gene be associated with susceptibility/resistance to mastitis and even with some economically important production traits. this study was carried out to det...
