BACKGROUND Peste des petits ruminants (PPR) is an economically important disease of small ruminants such as sheep and goats. The disease is characterized by severe pyrexia, oculo-nasal discharge, pneumonia, necrosis and ulceration of the mucous membrane and inflammation of the gastro-intestinal tract leading to severe diarrhea. A SYBR Green I based real time RT-PCR targeting the N gene of PPRV ...

PE Biosystems has developed guidelines enabling streamlined design and implementation of real-time quantitative PCR assays. The use of these guidelines makes it easy to apply either the fluorogenic 5 ́ nuclease assay or SYBR Green I double-stranded DNA binding dye chemistry to any real-time quantitative PCR system. Specific assay design and optimization guidelines minimize the time and cost of a...

Cytomegalovirus (CMV) infection is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Therefore, preemptive ganciclovir therapy based on early detection of CMV reactivation is widely used to prevent CMV disease. Real-time polymerase chain reaction (PCR) has been widely used for monitoring CMV reactivation as well as the antigenemia assay that...

The precise diagnosis of American tegumentary leishmaniasis (ATL) is an essential task due to the disease's associated morbidity. A noninvasive, extremely sensitive, and highly specific exam is critical, particularly for mucosal leishmaniasis (ML), in which a low parasite quantity is expected. We aimed to compare the diagnostic accuracy of swab and biopsy sample analysis using SYBR Green- and T...

INTRODUCTION Bluetongue (BT), a vector-borne viral disease, primarily affects sheep. Of the 26 serotypes of BTV identified so far, 22 are reported to be circulating in India. Due to an increase in vector population and delays in disease diagnosis, the BT control program heavily relies on rapid and confirmatory diagnosis. Polymerase chain reaction (PCR)-based real-time detection assays may be an...

Sensitive real-time sequence detection methods based on two different chemistries were developed for Mycobacterium avium subsp. paratuberculosis (Map), the causative agent of Johne's disease in cattle. One is based on the detection of SYBR Green bound to PCR products and the second method is more specific, detecting the cleavage of a fluorogenic (TaqMan) probe bound to a target sequence during ...

We report our experience with a new real-time polymerase chain reaction (PCR) assay applicable for simultaneous quantification and characterization of MBR/JH translocation in follicular lymphomas. This technique, which combines amplification with the FRET probe with SYBR Green I melting curve analysis, allows efficient detection of tumor cells in bone marrow or peripheral blood and their compar...
