The citrus systemic diseases, including Huanglongbing (caused by Candidatus Liberibacter asiaticus (CLas)), tristeza virus (CTV)), tatter leaf (CTLV)), and exocortis viroid (CEVd)), are threats to production in Taiwan. Reliable diagnostic methods important for the management of these diseases. In this study, we developed a multiplex reverse transcription–polymerase chain reaction (RT-PCR) assay...

Satsuma dwarf virus (SDV) or Citrus mosaic sadwavirus (CiMV) were not consistently detected in RT-PCR assay with the primer sets based on gene of Japan isolates. SDV and CiMV isolates were distinctively divided into two groups based on phylogenetic analysis of PP2 gene cloned from 22 Korean isolates, and the Korean CiMV and SDV isolates shared 95.5-96.2% and 97.1-97.7% sequence identity with Ja...

We utilized one-step multiplex reverse transcription-PCR (RT-PCR) and Luminex xMAP technology to develop a respiratory multiplex liquid-chip assay (rMLA) for simultaneous detection of 6 common respiratory viruses, including influenza virus type A (FluA) and type B (FluB), para-influenza virus type 3 (PIV-3), respiratory syncytial virus (RSV), human metapneumovirus (MPV) and a threatening virus ...

LATE-PCR is an optimized form of asymmetric PCR that efficiently generates high levels of single-stranded DNA amplicons. Single-stranded amplicons are advantageous because, as shown in this chapter, they can be probed at low temperature(s) with one or more probes. Based on its properties, LATE-PCR is also useful for constructing multiplex assays. Viral RNA or RNA present in cells can be detecte...

A qualitative multiplex reverse transcription (RT)-PCR and liquid hybridization assay for the detection of human enteroviruses, rhinoviruses, parechoviruses, and Aichi virus was developed. Furthermore, a separate assay for the recognition of hepatitis A virus was established to complement the test pattern so that all human picornaviruses were covered. The amplicons, which represented the 5' unt...

Background and Aims: Plant certification programs need reliable, fast, cheap and sensitive methods for detection of systemic pathogens with special interest in virus and viroid detection. Reverse transcriptase-polymerase chain reaction (RT-PCR) has been documented as an alternative assay for certification of plant propagating materials. The main object of the present study was the optimization ...

The paper describes a developed comprehensive system for molecular-genetic identification of Yersinia pestis strains according to their appurtenance certain subspecies, biovars, phylo-geographic populations, using realtime PCR (RT-PCR), allele-specific RT-PCR, and multiplex with hybridization fluorescent registration results on solid substrate. Application this makes it possible establish the Y...

Diagnosis of respiratory virus infections currently involves detection by isolation or antigen detection, which usually identifies only a single suspected agent. To permit identification of more than one respiratory virus in clinical specimens, a rapid detection method involving a single-step, multiplex reverse transcription-PCR (RT-PCR) assay was developed. The assay included five primer sets ...

OBJECTIVE To examine whether human endogenous retrovirus K10 is associated with autoimmune rheumatic disease. DESIGN A novel multiplex reverse transcription polymerase chain reaction (RT-PCR) system was developed to investigate HERV-K10 mRNA expression in patients with rheumatoid arthritis. METHODS 40 patients with rheumatoid arthritis, 17 with osteoarthritis, and 27 healthy individuals wer...

objective: chronic myeloid leukemia (cml) is a malignant clonal disorder of hematopoietic stem cells which results in increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. investigations have shown different types of bcr- abl variants in these patients. in iran only 3 types of these variants have been identified because most of the clin...
