Early diagnosis of Lassa fever by reverse transcription-PCR

Early diagnosis of Lassa fever by reverse transcription-PCR.

We developed a method based on a coupled reverse transcription-PCR (RT-PCR) for the detection of Lassa virus using primers specific for regions of the S RNA segment which are well conserved between isolates from Sierra Leone, Liberia, and Nigeria. The specificity of the assay was confirmed by Southern blotting with a chemiluminescent probe. The assay was able to detect 1 to 10 copies of a plasm...

Rapid and specific detection of Lassa virus by reverse transcription-PCR coupled with oligonucleotide array hybridization.

To facilitate sequence-specific detection of DNA amplified in a diagnostic reverse transcription (RT)-PCR for Lassa virus, we developed an array featuring 47 oligonucleotide probes for post-PCR hybridization of the amplicons. The array procedure may be performed with low-tech equipment and does not take longer than agarose gel detection.

Laboratory Diagnosis of Lassa Fever, Liberia

ports on Lassa fever in southern and central parts of Nigeria. That healthcare workers are still at as high a risk of contracting and dying from the disease as they were 20 years ago (8) is alarming. A key to solving this problem would be the establishment of diagnostic facilities that can provide rapid molecular testing at referral centers in the disease-endemic zones. This testing would facil...

Identification of introns by reverse-transcription PCR.

analyzing the gene of interest has several advantages over subcloning analysis. This method does not require any information about physical maps of the insert DNA. Positions of transposon insertion are presented as a distance from one end of the genomic DNA. Even if the restriction map is known, this technique should be preferable because of its simplicity. Using this protocol, it takes only on...
