Application of a Nested, Multiplex PCR to Psittacosis Outbreaks [PDF]

Journal of Clinical Microbiology, 1997
We developed a nested, multiplex PCR for simultaneous detection of three species of chlamydiae in human and avian specimens. The PCR was designed to increase sensitivity and to circumvent inhibitors of PCR present in clinical specimens. The target sequence was the 16S rRNA gene.

One-Tube Nested Real-Time PCR Assay for Rapid Screening of Porcine Cytomegalovirus in Clinical Samples

Frontiers in Veterinary Science, 2020
Porcine cytomegalovirus (PCMV) is a pathogen that must be removed from pigs for use as organ donors in xenotransplantation. Recently, it has been found that when donor pigs are infected with PCMV, a pig-to-non-human-primate xenotransplantation lower ...

An optimized one-tube, semi-nested PCR assay for Paracoccidioides brasiliensis detection

Revista da Sociedade Brasileira de Medicina Tropical, 2013
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

A semi-nested PCR assay for molecular detection of Paracoccidioides brasiliensis in tissue samples Semi-nested PCR para a detecção molecular de Paracoccidioides brasiliensis em amostras de tecido

Revista da Sociedade Brasileira de Medicina Tropical, 2010
INTRODUCTION: Paracoccidioidomycosis is a systemic infection caused by Paracoccidioides brasiliensis. METHODS: In this study, a semi-nested PCR for paracoccidioidomycosis diagnosis was developed. The primers ITS1 and ITS4 were used in the first reaction,

Tracking of Coetaneous Leishmaniasis by Parasitological, Molecular and Biochemical Analysis

Kufa Journal for Nursing Sciences, 2015
Background: In areas of endemicity without sufficient laboratory infrastructure, identification of Leishmaniaparasites is useful for control and preventive plan and very important since species differentiation is instrumental in selection of optimal ...

Nested PCR Analysis of Plasmodium Parasites [PDF]

, 2003
In the natural and untreated intermediate hosts, Plasmodium infections are maintained for extended and often lifelong periods. Parasitemia generally reaches its highest level in the first peak after inoculation, and only rises thereafter during increasingly brief and interspersed episodes. As the host acquires tolerance to higher numbers of multiplying

Nested PCR Assay for Detection of Granulocytic Ehrlichiae [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACT A sensitive and specific nested PCR assay was developed for the detection of granulocytic ehrlichiae. The assay amplifies the 16S rRNA gene and was used to examine acute-phase EDTA-blood and serum samples obtained from seven humans with clinical presentations compatible with human granulocytic ehrlichiosis.

Species-specific nested PCR as a diagnostic tool for Brucella ovis infection in rams

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
The aim of the present study was to evaluate a species-specific nested PCR based on a previously described species-specific PCR for detection of B. ovis in semen and urine samples of experimentally infected rams.

Comparison of nested PCR and real time PCR of Herpesvirus infections of central nervous system in HIV patients

BMC Infectious Diseases, 2004
Background Molecular detection of herpesviruses DNA is considered as the reference standard assay for diagnosis of central nervous system infections. In this study nested PCR and real time PCR techniques for detection of Herpes simplex virus type 1 (HSV ...

Comparison between four laboratory tests for routine diagnosis of enzootic bovine leukosis [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2022
The aim of this study was to compare the diagnostic capabilities of the agar gel immunodiff usion test (AGID) and two types of PCR, nested PCR (with nucleic acid extraction from blood) and direct blood nested PCR (db nested PCR) - without extraction, vs.
