BACKGROUND & OBJECTIVES Bats are recognized as important reservoirs for emerging infectious disease and some unknown viral diseases. Two novel viruses, Malsoor virus (family Bunyaviridae, genus, Phlebovirus) and a novel adenovirus (AdV) (family, Adenoviridae genus, Mastadenovirus), were identified from Rousettus bats in the Maharashtra State of India. This study was done to develop and optimize...
The gravimetric uterotrophic assay is currently the most well-established, short-term rodent estrogenicity assay. Increasing attention is being paid to the extent to which use of morphometric or molecular changes in the uterus could act as surrogates for the gravimetric end point of the assay, thereby perhaps increasing the sensitivity of the assay. In this paper I discuss the available data, p...
conclusions the in-house 1 step taqman real time rt-pcr assay showed acceptable performance characteristics. our study presents the robustness and cost-effectiveness of the method for detection and quantification of hcv rna. methods the primers and probe were selected from a highly conserved region of the hcv genome, which allowed the detection of 4 common hcv genotypes in iran. using 4 quantif...
background contamination of therapeutic recombinant proteins with residual host cell dna must be controlled under the regulatory standards. objectives the current study established a new rapid, sensitive real time polymerase chain reaction (pcr) approach to measure the reliably of the residual escherichia coli (e. coli) host cell genomic dna in the recombinant streptokinase and alfa interferon ...
INTRODUCTION Laboratory-based surveillance is an important component in the control of vancomycin resistant enterococci (VRE). METHODS The study aimed to evaluate real-time polymerase chain reaction (RT-PCR) (genes vanA-vanB) for VRE detection on 115 swabs from patients included in a surveillance program. RESULTS Sensitivity of RT-PCR was similar to primary culture (75% and 79.5%, respectiv...
avian infectious bronchitis (ib), caused by a gammacoronavirus, is an oie-listed (list b) disease and characterized by respiratory and renal involvements, causing high mortality, and economic loss in both layers and broilers. in comparison with other diagnostic methods, real-time polymerase chain reaction (rt-pcr) and conventional rt-pcr are potent, more sensitive and faster techniques for infe...
The current study reports on a real-time reverse transcription polymerase chain reaction (real-time RT-PCR) ring trial for the detection of Classical swine fever virus (CSFV) genomic RNA undertaken by 10 European laboratories. All laboratories were asked to use their routine in-house real-time RT-PCR protocols and a standardized protocol commonly used by the Friedrich-Loeffler-Institute (FLI) o...
background: influenza a virus is the most virulent human pathogen and causes the most serious problem. having epidemiological knowledge about this disease is important. the aim of this study was to determine the prevalence of influenza a/h3n2 virus infection in northern iran from 2011 to 2013 using the real-time polymerase chain reaction (rt-pcr). methods: in this cross-sectional study 57 sampl...
conclusions clinical signs and symptoms presented by patients infected with the influenza a h1n1 virus were similar to those described for seasonal influenza, although with more gastrointestinal disorders. results among the 232 enrolled cases, 126 patients (54.31%) were male and 106 patients (45.89%) were female. real time reverse rt-pcr test revealed that 18.1% of suspected children were posit...
