Viable Real-Time PCR in Environmental Samples: Can All Data Be Interpreted Directly?

Detection and enumeration of Cryptosporidium oocysts in environmental water samples by Real-time PCR assay

Introduction: The protozoan parasite, Cryptosporidium Spp., widely spreads in both raw and drinking waters. It is the causative agents of waterborne diarrhea and gastroenteritis in the world. In the present study, a molecular assay was used for the detection and quantification of Cryptosporidium oocysts in environmental water samples. Materials and methods: Thirty surface water samples wer...

Direct real-time PCR examination for Mycobacterium tuberculosis in respiratory samples can be cost effective

Aim: To assess whether the use of direct realtime polymerase chain reaction (PCR) on smear-positive sputa can be cost-effective, by speciating mycobacteria earlier than current methods and thereby preventing unnecessary screening tests as part of the contact tracing process. Methods: A retrospective study of all patients with smear-positive sputa in a Liverpool teaching hospital between 2004 an...

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...
