Reverse transcription PCR to detect low density malaria infections

Reverse transcription PCR to detect enteroviruses in surface water.

We have developed a simple, fast, and efficient procedure to detect enteroviruses in water samples. Aliquots of water are subjected to two-step filtration, with the second filter containing a positively charged nylon membrane that holds back virus particles. Viruses thus adsorbed are directly lysed, and RNA is isolated by hybridization to specific oligonucleotides bound to magnetic beads. The s...

One-Step Reverse Transcription PCR (RT-PCR). Fatemeh Mehrpooyan*

Sensitive and broadly reactive reverse transcription-PCR assays to detect novel paramyxoviruses.

We have developed a set of reverse transcription-PCR assays for the detection and identification of known and novel paramyxoviruses in clinical specimens. Primers were designed from the conserved motifs of the polymerase pol gene sequences to detect members of the Paramyxovirinae or Pneumovirinae subfamily or groups of genera within the Paramyxovirinae subfamily. The consensus-degenerate hybrid...

Real-Time Reverse Transcription PCR

Real-time, fluorescence-based reverse transcription polymerase chain reaction (RT-PCR) has been transformed from an experimental technology into a mainstream scientific tool for the detection of RNA. This is because of several factors: 1) it is a homogeneous assay, which eliminates the requirement for post-PCR processing; 2) it has a wide dynamic range; 3) there is little interassay variation; ...

Evaluation of real-time PCR assay to detect Schistosoma mansoni infections in a low endemic setting

BACKGROUND Schistosomiasis constitutes a major public health problem, and 200 million people are estimated to be infected with schistosomiasis worldwide. In Brazil, schistosomiasis has been reported in 19 states, showing areas of high and medium endemicity and a wide range of areas of low endemicity (ALE). Barra Mansa in Rio de Janeiro state has an estimated prevalence of 1%. ALE represent a ne...
