New Real-Time Quantitative PCR Procedure for Quantification of Bifidobacteria in Human Fecal Samples

Human Fecal Samples for Quantification of Bifidobacteria in New Real-Time Quantitative PCR Procedure

Quantification and Optimization of Candida albicans DNA in Blood Samples Using Real- Time PCR

Background: Candida albicans (C. albicans) is a major cause of candidaemia in people with impaired immunity. Blood culture is a “gold standard” for candidaemia detection but is time-consuming and relatively insensitive. We established a real-time PCR assay for C. albicans detection in blood by LightCycler PCR and melting curve analysis. Methods: Five milliliter blood samples from...

Human fecal source identification with real-time quantitative PCR.

Waterborne diseases represent a significant public health risk worldwide and can originate from contact with water contaminated with human fecal material. We describe a real-time quantitative PCR (qPCR) method that targets a genetic marker of the human-associated Bacteroides dorei for identification of human fecal pollution in ambient water samples. The following protocol includes water sample ...

Quantification of Shiga toxin-converting bacteriophages in wastewater and in fecal samples by real-time quantitative PCR.

Shiga toxin-converting bacteriophages (Stx phages) are involved in the pathogenicity of some enteric bacteria, such as Escherichia coli O157:H7. Stx phages are released from their bacterial hosts after lytic induction and remain free in the environment. Samples were analyzed for the presence of free Stx phages by an experimental approach based on the use of real-time quantitative PCR (qPCR), wh...

Evaluation of a new set of Real-Time PCR for Brucella detection within human and animal samples

A quantitative TaqMn Real-Time PCR assay was developed and its diagnostic value on human serum and livestock samples were evaluated. Brucella species could be distributed through communities as a biological agent. Rapid detection of biological threat agents is critical for timely therapeutic administration. Quantitative real-time PCR provides a rapid, sensitive and specific tool for molecular i...
