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 ...

background aggregatibacter actinomycetemcomitans and tannerella forsythensis are two major pathogens in destructive periodontal disease in humans. the detection of these bacteria is needed for diagnosis and management of the mentioned diseases. objectives we aimed to develop and compare improved multiplex conventional and sybr green real time pcr assays for a specific diagnosis of the organisms...

The nucleic acid stain SYBR Green I was evaluated for use with solid-phase laser cytometry to obtain total bacterial cell counts from several water sources with small bacterial numbers. Results were obtained within 30 min and exceeded or equaled counts on R2A agar plates incubated for 14 days at room temperature.

A real-time PCR assay using SYBR Green I for quantification of provirus load in a murine model of AIDS (i.e., LP-BM5 infection) was developed and validated. In this method, data are normalized against the 18S rRNA gene. The method has a dynamic range of 8 logs and a sensitivity of one copy.

A SYBR Green LightCycler PCR assay using a single primer pair allowed simultaneous detection of stx1 and/or stx2 of Escherichia coli O157:H7. A distinct sequence of the Shiga-like toxin genes was amplified to yield products of 227 and/or 224 bp, respectively. The two products were distinguished by melting point curve analysis.
