Strawberry anthracnose caused by Colletotrichum species is an important disease that may cause significant economic losses. Based on multilocus sequence analyses and morphological characteristics, 64 isolates from strawberry samples collected nine Chinese provinces municipalities were identified as three species: fructicola (29 isolates), siamense (23 nymphaeae (12 isolates). Isolates of C. sho...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....
Background and aim: Staphylococcus aureus can colonizes variety of body sites such as skin, coetaneous membrane and especially anterior nares. The coagulase gene (coa) typing is a technique in which the organism is typed based on the polymorphic region of the coa gene. The aim of the present study was to determine the coa based typing of S. aureus isolates from health care workers in two teach...
introduction recently acinetobacter baumannii isolates have emerged as a problematic infectious agent that causes meningitis in neurosurgical patients. colistin has been used successfully for the treatment of a. baumannii meningitis but colistin resistant isolates have been reported worldwide. case presentation two isolates of a. baumannii were cultured during a five-day period from cerebrospin...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
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...
Fusarium wilt caused by Fusarium oxysporum Schltdl. f.sp. phaseoli (Fop), is one of the important diseases of the common bean in Iran and many of the bean growing countries. Incidence of the disease has been reported in tropical and semi-tropical regions of the world. This study was carried out to characterize genetic diversity of F. oxysporum isolates from the common bean by vegetative compati...
conclusions our results showed that blaoxa-23 was the most prevalent gene, followed by blaoxa-51, among the burn and non-burn clinical isolates of a. baumannii. blaoxa-24-like genes were detected at a lower level and were only found among the burn isolates, which also showed higher heterogeneity compared to the non-burn group. background emergence of multidrug-resistant acinetobacter baumannii ...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
