abstract background and objective: paratuberculosis is a chronic granulomatous enteritis of ruminants caused by mycobacterium avium subspecies paratuberculosis (map). this study aimed to characterize the genome of the map 316f strain. methods: the map 316f strain was subjected to the pcr-f57 and pcr-is900 experiments in order to ensure its identity as map. this was followed by appl...
background and aims: genotyping assay has been accepted as a guidance in the therapeutic management of human immunodeficiency virus 1 (hiv-1). but, it is not commonly used in our country due to its high running cost. the aim of this study is evaluate an in-house genotyping resistance test (grt) for hiv-1. methods: hiv-1 rna of 20 samples were extracted from plasma and rt nested- pcr was perform...
background: the aim of this study was to apply the nested-pcr and bioassay methods in detection and genotyping of toxoplasma gondii infection in provided sheep aborted fetus samples from qazvin province of iran. methods : eighteen sheep aborted fetal samples were studied by nested-pcr-rflp, histopathological observation and microbiological assay. bioassay in mice was carried out by inoculating...
atopic dermatitis (ad) is a common chronically relapsing skin disease associated with abnormal cytokine production, and activation of t-helper 2 cells. the aim if this study was to determine whether cytokine gene polymorphisms might influence the development of ad. single nucleotide polymorphisms in the genes for i-l1alpha, il-1beta, il-1r, il-2, il-4, il-6, il-10, il-12, tgf beta, tnf and ifng...
Background: The High Resolution Melting (HRM) method is a new scanning method for detecting unknown changes in DNA and its advantages have persuaded researchers to recruit it as a screening method. Objectives: Here, we developed a HRM method to screen R188H SNP (rs3218536) of XRCC2 and compared the results with a well known PCR-RFLP technique. Materials and Methods: Genomic ...
the rs2476601 (r620w, c1858t) polymorphism in ptpn22 gene has been repeatedly reported to be associated with rheumatoid arthritis (ra). the rs 2476601 is widely suggested for predictive testing and risk assessment for ra. the aim of this study was to test the possible association of this snp with ra in iranian population.a total of 872 samples (405 confirmed ra patients and 467 healthy controls...
Abstract Genotyping individuals using forensic or non-invasive samples such as hair fecal increases the risk of allelic amplification failure (dropout) due to low quality and quantity DNA. One way decrease genotyping errors is increase number replicates per sample. Here, we have developed software SNP+ estimate dropout probability subsequent required obtain reliable genotype with 95%. Moreover,...
Existing HIV-1 genotyping systems require a computationally expensive phase of multiple sequence alignments and the alignments must have a sufficiently high quality for accurate genotyping. This is particularly a challenge when the number of strains is large. Here we propose a whole genome composition distance (WGCD) to measure the evolutionary closeness between two HIV-1 whole genomic RNA sequ...
Genome-wide association scans for disease susceptibility genes of complex diseases require genotyping on a massive scale. A DNA pooling strategy for family-based association studies is described, which is robust to population stratification biases and to errors in pooling. It can achieve a statistical efficiency of 0.95 with approximately 1 of 8 or fewer genotyping efforts, and an efficiency of...
Spots of blood are routinely collected from newborn babies onto filter paper called Guthrie cards and used to screen for metabolic and genetic disorders. The archived dried blood spots are an important and precious resource for genomic research. Whole genome amplification of dried blood spot DNA has been used to provide DNA for genome-wide SNP genotyping. Here we describe a 96 well format proce...
