Growing consumer awareness is forcing food producers to supply raw material and products of increasingly high quality health-promoting properties. Knowledge the genetic background characteristics taking on great importance, enabling selection based molecular markers. The increasing throughput techniques, in combination with an expanding bioinformatics infrastructure, leading continual improveme...
The present study was aimed to understand the molecular epidemiology of Staphylococcus aureus (54 isolates), isolated from 422 milk samples obtained 108 subclinical mastitis affected cows (CMT positive ≥1+ in at least one quarter). studied using coagulase (coa) gene polymorphism, 16S-23S ribosomal spascer (RS-PCR) polymorphism and Staphylococcal protein A (Spa) typing. produced 7 genotypes 8 RS...
Background: Cellular tolerance to heat stress is mediated by shock proteins (HSPs). The HSPs act as molecular chaperones and are transcribed in response stress. Among different families of these proteins, HSP70 considered be related the development temperature tolerance. Unraveling polymorphism protein genes could a step towards identification genetic markers for selecting heat-tolerant cattle....
Molecular typing of twenty-five Pasteurella multocida isolates has been assessed by restriction fragmentlength polymorphism (RFLP) of a species-specific PCR assay. Amplification was based on the gene ompH, encoding a major outer memberane protein. RFLP analysis of the 1.2 kb ompH-amplification usingEcoRI, HindIII and CfoI endonucleases produced 7 different patterns for the twenty fi...
The poor information available on variation of Ascochyta blight fungus is the most important factor limiting chickpea breeding programs for resistance to blight disease. In this study, efforts were made to detect genetic variation of the pathogen in Iran. The RAPD marker was employed to evaluate 26 isolates collected from 16 provinces. Twelve random primers were used to analyze genomic DNA of t...
Skin cancer is one of the most important type of cancers in the world. In this way, molecular investigation in order to detect some novel mechanisms and polymorphisms involved in cancer development can be impressive and vital. In this way, the aim of this study was the histopathological investigation of skin cancer and its relationship with polymorphism of CDKN2A gene. This case-control study w...
The degree to which molecular epidemiology reveals information about the sources and transmission patterns of an outbreak depends on the resolution of the technology used and the samples studied. Isolates of Escherichia coli O104:H4 from the outbreak centered in Germany in May-July 2011, and the much smaller outbreak in southwest France in June 2011, were indistinguishable by standard tests. We...
vulvovaginal candidiasis (vvc) is a common disease among women worldwide, therefore, accurate and rapid diagnosis of causative agents based on molecular techniques utilizing amplification of target dna is highly recomendad for epidemiological purposes and for effective treatment. the aim of this study was to identify clinically candida species from vvc patients by restriction fragment length po...
Twenty-four start codon targeted (SCoT) markers were used to assess genetic diversity and population structure of indigenous, introduced and domesticated ramie (Boehmeria nivea L. Gaudich.). A total of 155 genotypes from five populations were investigated for SCoT polymorphism, which produced 136 amplicons with 87.5% polymorphism. Polymorphism information content and resolving power of the SCoT...
The dojo loach Misgurnus anguillicaudatus is an endemic freshwater species in Asia. effective conservation and molecular-aided selection of M. were limited without sufficient molecular markers. In this study, 112 novel single nucleotide polymorphism (SNP) markers screened based on 2b-RAD sequencing database, 56 SNPs them developed characterized by genotyping 40 individuals using SNaPshot method...
