TLDR
The exquisite sensitivity of the polymerase chain reaction means DNA contamination can ruin an entire experiment and adherence to a strict set of protocols can avoid disaster.
Abstract
The exquisite sensitivity of the polymerase chain reaction means DNA contamination can ruin an entire experiment. Tidiness and adherence to a strict set of protocols can avoid disaster.

Diagnosis of Cat Scratch Disease with Detection of Bartonella henselae by PCR: a Study of Patients with Lymph Node Enlargement

TL;DR: A study was performed to determine the diagnostic value of PCR analysis for the detection of B. henselae for the diagnosis of CSD and its place in the diagnostic strategy alongside the classical criteria.
Journal ArticleDOI

Hepatitis C Virus Replicates in the Liver of Patients Who Have a Sustained Response to Antiviral Treatment

TL;DR: HCV persisted and replicated in the livers and peripheral blood mononuclear cells of most sustained responders, and these patients did not experience HCV infection clearance, despite apparent clinical disease resolution.
Journal ArticleDOI

"Cytomegalovirus disease" in renal allograft recipients: Is human herpesvirus 7 a Co-factor for disease progression?

TL;DR: It is concluded that in patients with CMV DNAemia, concurrent infection/reactivation of HHV7 (and possibly HHV6) is associated with an increased risk of progression to “CMV disease.”
Journal ArticleDOI

Detection of HIV-1 gene sequences in hippocampal neurons isolated from postmortem AIDS brains by laser capture microdissection.

TL;DR: The results indicate that brain neurons in vivo contain HIV-1 DNA sequences consistent with latent infection by this virus, and suggest that neurons display a selective vulnerability for HIV infection.
Journal ArticleDOI

Evaluation of the range of clinical presentations of herpes simplex encephalitis by using polymerase chain reaction assay of cerebrospinal fluid samples.

TL;DR: In this study, PCR assay of CSF samples obtained from 29 patients with focal, mild, and diffuse encephalitis, respectively, was performed and revealed that atypical and less severe forms ofEncephalitis are caused by herpes simplex virus.

Primer-directed enzymatic amplification of DNA with a thermostable DNA polymerase

TL;DR: A thermostable DNA polymerase was used in an in vitro DNA amplification procedure, the polymerase chain reaction, which significantly improves the specificity, yield, sensitivity, and length of products that can be amplified.
Book ChapterDOI

Specific synthesis of DNA in vitro via a polymerase-catalyzed chain reaction.

TL;DR: A method whereby a nucleic acid sequence can be exponentially amplified in vitro is described in the chapter, and the possibility of utilizing a heat-stable DNA polymerase is explored so as to avoid the need for addition of new enzyme after each cycle of thermal denaturation.
Journal ArticleDOI

DNA amplification for direct detection of HIV-1 in DNA of peripheral blood mononuclear cells

TL;DR: This method of DNA amplification made it possible to obtain results within 3 days, whereas virus isolation takes up to 3 to 4 weeks, and may therefore be used to complement or replace virus isolation as a routine means of determining HIV-1 infection.
Journal ArticleDOI

DNA typing from single hairs

TL;DR: Three different means of DNA typing are used for the determination of amplified DNA fragment length differences, hybridization with allele-specific oligonucleotide probes, and direct DNA sequencing on single human hairs to detect genetically variable mitochondrial and nuclear DNA sequences.
Journal ArticleDOI

Amplification and analysis of DNA sequences in single human sperm and diploid cells

TL;DR: The use of the polymerase chain reaction for analysing DNA sequences in individual diploid cells and human sperm shows that two genetic loci can be co-amplified from a single sperm, which may allow the analysis of previously inaccessible genetic phenomena.
