The Gibberella fujikuroi species complex with Fusarium anamorphs is the causal of diverse diseases of many important plants. Many of the known species in this species complex produce a wide range of secondary metabolites. In this study, morphological characteristics of 46 isolates from rice, maize, sugarcane and onion and phylogenetic relationships of 22 isolates on the basis of ITS1-5.8S-ITS2 ...

In order to determine the causal agents of Fusarium head blight, during 2015–16, wheat heads with disease symptom were collected from 10 and six main wheat production areas of Golestan and Mazandaran provinces (N Iran), respectively. A total of 431 Fusarium isolates were obtained belonging to nine Fusarium species based on their morphological characteristics. Fusarium graminearum species comple...

study of some growth promotion properties of bacterial isolates from animal manures and identification of selected isolatesabstractbackground and objectives: plants growth in agricultural soils are affected by several biological factors. plant growth promoting bacteria can improve growth and yield of agronomic plants through direct and indirect mechanisms. minimizing consequences of using high ...

Enterococci are Gram positive and catalase- negative cocci that are found in the gastrointestinal tract of mammals and birds, and are readily isolated from soil, surface and waters. The aim of this study was to discriminate between Enterococcus isolates based on repetitive element sequence based –PCR (Rep-PCR) with the BOXA2R primer and their antibiotics profile. Enterococci isolates were obtai...

During 2008, the presence of Paecilomyces species was studied in fields in Fars province. Soil samples were collected from 0–20 cm depth. The isolates were recovered using a soil dilution plate method directly from soil. Isolation was performed from soil using malt extract agar, rice agar, oat-meal agar and potato dextrose agar. Anamorphic characteristics such as morphology of conidiophores, ph...

results out of 2229 suspected meningitis cases, 255 (11.4%) were detected as positive culture. most of the isolates were gram-positive cocci, which 116 (45.5%) were staphylococcus epidermidis, and 20 (7.8%) identified as streptococcus spp. among gram-negative isolates, escherichia coli and acinetobacter spp., each with 19 isolates (5.9%), were predominant. overall, the most effective antibiotic...

In the present study 14 bacterial strains were isolated from root nodule of Crotolaria junceae L. from 4 different sites of Assam. The isolates were investigated for their morphological characteristics. Three different confirmatory tests were performed with the isolates. The isolates were also investigated for their biochemical characteristics and compared with biochemical characteristics of re...

An investigation was carried out in some areas of Golestan Province including: Loveh forest, Soosara, Daland forest park, Tooskestan; Gilan Province including Siahkal and Asalem forests; Arasbaran and landscape of urban trees during 1999–2007. In this investigation, based on some morphological, physiological and molecular characteristics and also comparison with standard isolates two species Op...

One hundred isolates of Fusarium solani species complex were isolated and identified from 58 agricultural soil samples collected from different geographical regions in Kermanshah, Hamadan and Kurdistan provinces of Iran. Based on morphological characteristics, Fusarium falciforme, F. petroliphilum, F. keratoplasticum and F. pseudensiforme, are reported for the first time from Iran.
