The genus Fusarium is a species rich genus. Different media are required to study the morphological characters and classify different species, a time consuming technique. In this study pectic zymograms were used to identify species and form species of Fusarium isolates. Fusarium isolates (318) were obtained from different areas and hosts in Isfahan Province, Iran. Isolates were identified to sp...
Background and Aims : Oxacillin-resistant Staphylococcus aureus is a major pathogen causing serious infections and treatment of such infections is very difficult. Vancomycin is the last line of treatment for resistant S. aureus. The aim of this study was investigation of epidemiology of vancomycin and oxacillin resistant Staphylococcus aureus clinical isolates in Urmia Materials and Methods...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
Fusarium culmorum is one of the species causing Fusarium head blight (FHB) in cereals in Europe. We aimed to investigate the association between the nucleotide diversity of ten F. culmorum candidate genes and field ratings of aggressiveness in winter rye. A total of 100 F. culmorum isolates collected from natural infections were phenotyped for FHB at two locations and two years. Variance compon...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
Fusarium wilt of eggplant is a major cause losses to production globally. The disease caused by many species. In this study, incidence, diversity and distribution pathogens eggplants were determined in five communities each from Ashanti, Eastern Volta Regions Ghana during the 2017–2019 cropping seasons. Purposive sampling method was used select 10 farms infected with community. Infected sampled...
the severe epidemics of fusarium head blight (fhb) as a devastating disease of cereal crops has occurred on wheat in north and northwest iran in recent years. the in vitro production of deoxynivalenol (don) was qualitatively evaluated in 41 fusarium isolates collected from wheat heads associated with the scab disease, in moghan area/northwest iran. infected wheat heads were collected during 200...
Avian pneumovirus (APV) was first isolated from turkeys in the west-central US following emergence of turkey rhinotracheitis (TRT) during 1996. Subsequently, several APV isolates were obtained from the north-central US. Matrix (M) and fusion (F) protein genes of these isolates were examined for sequence heterogeneity and compared with European APV subtypes A and B. Among US isolates the M gene ...
Background & Aims: Fascioliasis caused by Fasciola hepatica and Fasciola gigantica has medical and economic importance in the world. Traditional approaches are not accurate and reliable in identification of agent parasites. Thus the present study was designed to identify the Fasciola sppby molecular methods in West Azerbaijan province.Materials & Methods: In current study Fasciola isolates wer...
Abstract Fusarium is one of the most important genera phytopathogenic fungi, causing potato wilt in field and tuber dry rot during storage. The objectives this study were to identify species associated with both diseases different growing regions Algeria, assess their pathogenicity. Among 152 isolates collected from symptomatic plants tubers provinces 13 Neocosmospora identified. these three is...
