The ongoing outbreaks of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has led to a worldwide pandemic Disease (COVID-19) in 2019. Nucleic Acid Tests as the current most prevalent method are able detect presence SARS-CoV-2 from infected patients by comparing target viral genome sequences high sensitivity and accuracy. Three widely applied nucleic acid methods for clinical researc...

INTRODUCTION Diagnosis of brucellosis in Syria is based on the presence of compatible symptoms in addition to positive agglutination results. This study investigated the potential of culture, ELISA and real-time PCR to support the diagnosis in different clinical manifestations of brucellosis. METHODOLOGY Peripheral blood samples from 34 suspected brucellosis patients and 42 probable chronic o...

Introduction. Polymerase chain reaction (PCR)-based diagnostic tests use purifi ed nucleic acids (NAs) from clinical samples. The NAs cation step adds time, cost, and aff ects the quality of testing. objective this study was to develop a protocol for direct saliva in genetic markers, without acids. Methods. PCR, real-time RT-PCR isothermal amplifi were used detection Results. We report markers ...

Molecular diagnostic techniques, such as polymerase chain reaction (PCR), are promising tools for the rapid etiological diagnosis of pneumonia. PCR offers potential advantages over conventional tests for the detection of Mycoplasma pneumoniae, Legionella species, and Chlamydia pneumoniae. For pneumococcal pneumonia in adults, PCR adds little to existing diagnostic tests and is unable to disting...

It has been demonstrated that the use of additional information such as ESTs and protein homology can significantly improve accuracy of gene prediction. However, many sources of external information are still being omitted from consideration. Here, we investigate the use of product lengths from RT-PCR experiments in gene finding. We present hardness results and practical algorithms for several ...

The correct identification of Candida species is of great importance, as it presents prognostic and therapeutical significance, allowing an early and appropriate antifungical therapy. The purpose of this study was to identify isolates of Candida spp. from oral mucosa of 38 patients with oral candidosis evaluated in 2004 by phenotypic methods and PCR, discriminating C. albicans from the other Ca...

We studied the diagnostic performance of the IRIDICA PCR/electrospray ionization-mass spectrometry (PCR/ESI-MS) assay applied on bronchoalveolar lavage (BAL) samples, from 51 mechanically ventilated patients with suspected pneumonia, in a prospective study. In 32 patients with X-ray verified pneumonia, PCR/ESI-MS was positive in 66% and BAL culture was positive in 38% (p = 0.045), and either of...
