Rapid and sensitive detection of Mycobacterium tuberculosis (M. Tb) in cerebrospinal fluid is crucial in the diagnosis of tuberculous meningitis (TBM), but conventional diagnostic technologies have limited sensitivity and specificity or are time-consuming. In this work, a novel, highly sensitive molecular diagnostic method, one-tube nested PCR-lateral flow strip test (OTNPCR-LFST), was develope...

evidences from many studies suggested a polymerase chain reaction (pcr) as a valuable method for diagnosing infectious disease in the transplant recipients. we used this method for detection of toxoplasma, gondii and human cytomegalovirus in blood specimens from patients after bone marrow or kidney transplantation. dna of both infectious agents were detected using two separate sets of nested pr...

There is a growing appreciation of the potential value for routine screening for the presence of HPV not only for cervical specimens but also from oral cavity. The purpose of this study was to develop and clinically evaluate a single-tube seminested PCR assay for the detection of HPV. Several parameters such as PCR primers, primer annealing temperature, the number of PCR cycles and concentratio...

INTRODUCTION Herein, we report a one-tube, semi-nested-polymerase chain reaction (OTsn-PCR) assay for the detection of Paracoccidioides brasiliensis. METHODS We developed the OTsn-PCR assay for the detection of P. brasiliensis in clinical specimens and compared it with other PCR methods. RESULTS The OTsn-PCR assay was positive for all clinical samples, and the detection limit was better or ...

Several methods for the detection of Borna disease virus (BDV) RNA have been reported, one being the reverse transcription-nested polymerase chain reaction (RT-nested PCR) method. However, due to the possibility of contamination of the cloned DNA in a reaction tube, false-positive results might be obtained by RT-nested PCR. To detect only BDV RNA without anxiety of contamination, we developed a...

A device and improved method based on the use of a compartmentalized Eppendorf tube that allows capture, reverse transcription and nested-PCR in a single closed-tube has been developed and patented. The main advantages of the system are the high sensitivity obtained, the simplicity, the low risk of contamination and the easy establishment of adequate conditions for nested-PCR. The method has be...

Classical swine fever (CSF) is a notifiable, highly contagious disease of swine controlled mainly with costly administrative methods. Swine may be infected not only with classical swine fever virus (CSFV), but also with other, non porcine, genetically and antigenically related pestiviruses. Differentiation of infections with CSFV and other pestiviruses is a crucial element of diagnostics. In th...
