Rapid Detection and Quantification of Rhynchosporium secalis in Barley Using a Polymerase Chain Reaction

Rapid Detection and Quantification of Rhynchosporium secalis in Barley Using a Polymerase Chain Reaction

PCR primers for diagnosis of Rhynchosporium secalis in seed samples of barley were developed. For the quantification of the pathogen in seed samples a real-time PCR with SYBR Green approach was used. Amounts from 1.8 to 419.1 pg of R. secalis DNA per 100 ng of total DNA were detected in 18 samples of barley seeds contaminated by R. secalis in field conditions. The correctness of this quantitati...

Transcriptome Analysis of the Barley-Rhynchosporium secalis Interaction

Leaf scald caused by the infection of Rhynchosporium secalis, is a worldwide crop disease resulting in significant loss of barley yield. In this study, a systematic sequencing of expressed sequence tags (ESTs) was chosen to obtain a global picture of the assembly of genes involved in pathogenesis. To identify a large number of plant ESTs, which are induced at different time points, an amplified...

Rapid Detection of Campylobacter jejuni by Polymerase Chain Reaction and Evaluation of its Sensitivity and Specificity

Introduction: Campylobacter jejuni is one of the most common causes of food poising in humans. Rapid and specific detection of these bacteria has an important role in diagnosis and treatment of infection. The aim of this study was to design a specific PCR for the detection of Campylobacter jejuni. Methods: In this experimental study, oxidoreductase gene from the Campylobacter jejuni was sele...

RAPID DETECTION OF MYCOBACTERIUM TUBERCULOSIS IN CLINICAL SPECIMENS BY POLYMERASE CHAIN REACTION

We investigated the use of DNA amplification by polymerase chain reaction (peR) for detection of Mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with PCR. Two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared fo...
