this study was carried out to identify fusarium species associated with sugar beet root rot and yellows. pathogenicity of fusarium oxysporum, the causal agent of fusariumyellows of sugar beet was also investigated. samples of infected roots were collected from fields in major sugar beet producing areas in khorasan province during 1999-2000. infected roots were washed, surface sterilised and pla...

Mirzapour S, Darvishnia M, Bazgir E, Mirzaei Najafgholi H (2020) Pathogenic variation of Didymella rabiei isolates causing Chickpea blight in three western provinces of Iran. Plant Pathology Science 9(2):1-13. DOI: 10.2982/PPS.9.2.1   Introduction: Chickpea blight, caused by Didymella rabiei, is the most limiting factor in chickpea production areas in the world, including the western province...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

diseased samples with root rot symptoms were collected from different sugar beet growing areas. from rotted roots, 20 fungal isolates were identified as fusarium solani based on morphological characteristics .pathogenecity of the isolates was studied in in vitro condition on sugar beet roots. the results showed pathogenic variability among the isolates. cluster analysis divided the isolates int...

Background; Escherichia coli cause extraintestinal infections in both community and hospitalized patients. The prevalence of multidrug-resistant extraintestinal pathogenic E.coli has increased progressively over the past few years. Aim of this study is to determine the drug susceptibility pattern of Extraintestinal Pathogenic E.coli (EXPEC) isolated from various clinical isolates in the hospita...

pathogenicity and genetic variability of 13 fusarium oxysporum isolates collected from sugar beet field of six provinces of iran during 1999- 2008 were evaluated. pathogenic variability of the isolates was determined using a root-dip assay in spore suspension in test tubes for four- week plants. the isolates were classified into strong and weak pathogenic groups. a total of 15 rapd primers were...

background: the main goal of the present study was to set up an axenic cultivation of acanthamoeba and assess the pathogenic ability of t4 genotypes from different clinical and environmental strains of acanthamoeba using two physical assays. methods: sixteen acanthamoeba isolates including 10 environmental and 6 clinical strains were cul-tured axenically. axenic cultivation was performed using ...

acanthamoeba keratitis is a vision-threatening infection caused by pathogenic species of the genus acanthamoeba. in this study, 13 acanthamoeba keratitis cases were diagnosed among 52 keratitis patients. to confirm the identity of acanthamoeba at the genus level, a pcr-based method was used, and their pathogenic potential was determined using in vitro cytotoxicity assays on human corneal epithe...
