â â background hepatitis c virus (hcv) infection is responsible for considerable morbidity and mortality worldwide. the hcv genotype has a geographic distribution and an important role in clinical and histological outcomes. this study determined hcv genotypes and their related risk factors among patients from khuzestan province, southwest iran. methods in a cross-sectional study, 223 patients...
BACKGROUND Nails contain genomic DNA that can be used for genetic analyses, which is attractive for large epidemiologic studies that have collected or are planning to collect nail clippings. Study participants will more readily participate in a study when asked to provide nail samples than when asked to provide a blood sample. In addition, nails are easy and cheap to obtain and store compared w...
Background: Escherichia coli is a commensal-pathogenic organism, which includes a wide range of strains. Despite several advanced molecular-genomic technologies for detecting and identifying different strains of E. coli, Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR) technique is ...
The discipline of molecular ecology has undergone enormous changes since the journal bearing its name was launched approximately two decades ago. The field has seen great strides in analytical methods development, made groundbreaking discoveries and experienced a revolution in genotyping technology. Here, we provide brief perspectives on the main subdisciplines of molecular ecology, describe ke...
background: the aim of this study was to determine the prevalence of virulence-associated genes and enterobacterial repetitive intergenic consensus pcr (eric-pcr) analysis of campylobacter spp. isolated from children with diarrhea in iran. methods: a total of 200 stool specimens were obtained from children under 5 years during july 2012 to july 2013. detection of c. jejuni and c. coli was perfo...
results the highest prevalent genotype was genotype 4a, which was found in 57 patients (92%) followed by 2 isolates (3%) with genotype 4o, 2 strains (3%) with genotype 1g and one isolate (2%) with genotype 4n. conclusions this molecular epidemiology study revealed high prevalence of hcv genotype 4, subtype 4a among egyptian patients residing in sharkia governorate, egypt. patients and methods t...
background and aims: rubella virus is a human pathogen that causes congenital rubella syndrome (crs) when infection occurs during early pregnancy. vaccination programs have been remarkably successful in controlling natural rubella infection and crs. moreover, ongoing surveillance for all cases of rubella and crs is a vital component of a prevention program. although the who recommends the use o...
Serology, defined as antibody-based diagnostics, has been regarded as the diagnostic gold standard in transfusion medicine. Nowadays however the impact of molecular diagnostics in transfusion medicine is rapidly growing. Molecular diagnostics can improve tissue typing (HLA typing), increase safety of blood products (NAT testing of infectious diseases), and enable blood group typing in difficult...
When a fluorescent molecule is excited by plane polarized light, the fluorescence emitted is also polarized. The degree of fluorescence polarization (FP) detected, under constant temperature and solvent viscosity, is proportional to the molecular weight of the dye molecule. By monitoring the FP of a fluorescent dye, one can detect significant changes in the molecular weight of the molecule with...
