Hybrid gene PML-RARα is the molecular target found in most cases of acute promyelocytic leukemia (APL) and has been used for diagnosis and minimal residual disease studies. The standard molecular technique employed is qualitative reverse transcriptase-polymerase chain reaction (RT-PCR), but with the emergence of real time PCR (Q-PCR), PML-RARα gene detection approaches have been described allow...

A procedure has been developed for the rapid detection of enteroviruses and adenoviruses in environmental samples. Several systems for virus concentration and extraction of nucleic acid were tested by adding adenovirus type 2 and poliovirus type 1 to different sewage samples. The most promising method for virus recovery involved the concentration of viruses by centrifugation and elution of the ...

Distinguishing herpes virus infection from other skin diseases is sometimes difficult. This study aims to detect herpes virus DNA by multiplex real-time PCR without nucleic acid extraction in a short period of time. Specimens of cutaneous vesicles and swabs were obtained from 23 patients suspected of having herpes virus infection. These specimens were stored at -80 degrees C after dissolving th...

armillaria root and crown rot is an important disease of woody plants including fruit, forest and ornamental trees in different regions. the disease is common in isfahan and causes economical losses on a broad range of fruit trees. there only a few tolerant varieties to disease, and there is no efficient method in controlling the disease. therefore, detection of the pathogen from soil is necess...

The aim of this study was to develop a highly sensitive and specific one-step duplex reverse transcriptase PCR (RT-PCR) assay for the simultaneous and differential detection of West Nile (WNV) and Japanese encephalitis (JEV) viruses. The bioinformatic analysis of published sequences of WNV and JEV revealed conserved regions not targeted by previously reported primers. A total of 13 primers were...

A highly sensitive one-step multiplex RT-PCR (OMRT-PCR) system with an internal plant gene control was developed to simultaneously detect single and mixed RNA DNA viral pathogens affecting watermelon squash in the Southeastern United States. Current methods rely on a singleplex detection for several viruses which is time-consuming large-scale field monitoring. The gene-specific primers one viru...

conclusions this study showed that this novel one-step rrt-pcr assay is a rapid, reliable, repeatable, specific, sensitive, and simple tool for the detection of the cchf virus. results from a total of 75 suspected serum samples, 42 were confirmed to be positive for cchf virus, with no false-positives detected by the sequencing results. after 40 amplification cycles, the melting curve analysis r...
