Clinical Clostridium difficile isolates of patients with diarrhea or pseudomembranous colitis usually produce both toxin A and toxin B, but an increasing number of reports mention infections due to toxin A-negative, toxin B-positive (A(-)/B(+)) strains. Thirty-nine clinical toxin A(-)/B(+) isolates, and 12 other unrelated isolates were obtained from Canada, the United States, Poland, the United...
The worldwide prevalence of highly resistant Gram-negative rods (HR-GNR) is increasing rapidly. Reliable typing methods are needed to detect and control outbreaks and to monitor the effectiveness of infection control programs in endemic situations. In this study, we investigated the performance of the DiversiLab typing method in comparison with the amplified fragment length polymorphism (AFLP) ...
In the current investigation, 10 IRAP, 14 REMAP, 16 ISSR and 7 SSR primers and mixed linear model (MLM)-based association analysis were used to identify molecular markers associated with 13 morphological traits in cultivated alfalfa (Medicago sativa L.). Morphological traits studied, were height, chlorophyll content, total wet weight, total dry weight, wet leaf weight, dry leaf weight, wet stem...
Acute fatty liver of pregnancy (AFLP) is a rare liver disease unique to pregnancy that can lead to acute liver failure. Clinicians must have a high index of suspicion for AFLP because only early diagnosis and prompt delivery improve maternal and fetal prognosis.
زعفران یکی از با ارزش ترین گیاهان دارویی و ادویه ای در جهان است. با وجود قدمت کشت طولانی این گیاه در کشور، مطالعات اصلاحی محدودی به واسطه تولیدمثل غیرجنسی این گیاه انجام شده است. به منظور ارزیابی تنوع ژنتیکی ژرم پلاسم زعفران ایران، 65 نمونه مختلف زعفران از نواحی عمده کشت در خراسان شامل تربت حیدریه، گناباد، مه ولات، قائنات و فردوس جمع آوری و از طریق نشانگرهای مولکولی مورد مطالعه قرار گرفت. آغازگ...
DNA markers are commonly used for large-scale evaluation of genetic diversity in farm animals, as a component of the management of animal genetic resources. AFLP markers are useful for such studies as they can be generated relatively simply; however, challenges in analysis arise from their dominant scoring and the low level of polymorphism of some markers. This paper describes the results obtai...
Three different DNA-based techniques, Random Amplified Polymorphic DNA (RAPD), Inter Simple Sequence Repeat (ISSR) and Amplified Fragment Length Polymorphism (AFLP) markers, were used for fingerprinting Dactylis glomerata genotypes and for detecting genetic variation between the three different subspecies. In this study, RAPD assays produced 97 bands, of which 40 were polymorphic (41.2%). The I...
Sorghum is an important target for plant genomic mapping because of its adaptation to harsh environments, diverse germplasm collection, and value for comparing the genomes of grass species such as corn and rice. The construction of an integrated genetic and physical map of the sorghum genome (750 Mbp) is a primary goal of our sorghum genome project. To help accomplish this task, we have develop...
Contamination routes of Listeria monocytogenes were examined in a chilled food processing plant that produced ready-to-eat and ready-to-reheat meals during an 8-year period by amplified fragment length polymorphism (AFLP) analysis. A total of 319 L. monocytogenes isolates were recovered from raw materials (n = 18), the environment (n = 77), equipment (n = 193), and products (n = 31), and 18 dif...
تنوع ژنتیکی گیاهان زراعی با گذشت زمان کاهش پیدا کرده است. ارزیابی تنوع ژنتیکی در کارایی حفاظت از ژرم پلاسم وکاربرد آن حائز اهمیت می باشد (رشیدی و همکاران , 1386) . آگاهی دقیق از تنوع ژنتیکی مجموعه های ژنتیکی ضمن حفظ ذخایر ژنتیکی، قابلیت استفاده از آنها را در برنامه های اصلاحی تسهیل می نماید(mohamadi and prasna,2003 ). مطالعه تنوع ژنتیکی فرایندی است که تفاوت بین افراد، جمعیتها و یا گروهها با است...
