Rapid detection of filoviruses by real-time TaqMan polymerase chain reaction assays

Rapid Detection of Porcine Circovirus Type 2 by TaqMan-based Real-time Polymerase Chain Reaction Assays

PCV2 is the primary causative agent of porcine circovirus-associated disease (PCVAD). In this study, a TaqMan-based real-time polymerase chain reaction (PCR) assay targeting ORF2 gene of PCV2 was developed and their sensitivities and specificities were investigated. The results indicated that the standard curve had a wide dynamic range (102-107copies/μL) with a linear correlation (R2) of 0.997 ...

Detection of Nocardia Asteroides Complex in Clinical Isolates by Real-Time Polymerase Chain Reaction

Background and Aims: Nocardia asteroides complex is the most common cause of infectious diseases due to nocardiosis. Interspecies differentiation of Nocardia genera is essential for prognosis and timely proper treatment, as well as for epidemiological studies. Since each genus has its own antibiotic resistance, precise careful diagnosis is of prime importance. As compared to biochemical and phe...

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...
