Newcastle Disease Virus Detection from Chicken Organ Samples Using Reverse Transcriptase Polymerase Chain Reaction

Reverse transcriptase-polymerase chain reaction (rt-PCR).

Reverse transcriptase polymerase chain reaction (RT-PCR) has become a well-established and powerful molecular technique for studying ribonucleic acids. It is used in medical diagnostics for detecting viral RNA, in hematology and oncology for detecting chimeric transcripts of rearranged genes (1), and in the broad area of research applications in gene expression studies. Since its introduction (...

Detection of Plasmodium falciparum Directly from Blood Samples Using the Polymerase Chain Reaction

Analysis of respiratory syncytial virus in clinical samples by reverse transcriptase-polymerase chain reaction restriction mapping.

The aim of this study was to develop a polymerase chain reaction (PCR) for the detection of respiratory syncytial virus (RSV) genomes. The primers were designed from published sequences and selected from conserved regions of the genome encoding for the N protein of subgroups A and B of RSV. PCR was applied to 20 specimens from children admitted to the respiratory ward of "William Soler" Pediatr...

Usefulness of reverse transcriptase-polymerase chain reaction for detection of rabies RNA in archival samples.

The examination of archival samples by molecular techniques has been found to be a valuable tool in providing retrospective and epidemiological data. In contrast to DNA, there are fewer comprehensive studies quantitatively addressing the feasibility of assessing RNA from archival samples. In tropical countries like India, such studies are even more rare. One problem is that the warm climate and...

Rapid detection and typing of dengue viruses from clinical samples by using reverse transcriptase-polymerase chain reaction.

We report on the development and application of a rapid assay for detecting and typing dengue viruses. Oligonucleotide consensus primers were designed to anneal to any of the four dengue virus types and amplify a 511-bp product in a reverse transcriptase-polymerase chain reaction (PCR). First, we produced a cDNA copy of a portion of the viral genome in a reverse transcriptase reaction in the pr...
