Human papillomavirus detection and typing using a nested-PCR-RFLP assay

Brazilian Journal of Infectious Diseases, 2011
Background: It is clinically important to detect and type human papillomavirus (HPV) in a sensitive and specific manner. Objectives: Development of a nested-polymerase chain reaction-restriction fragment length polymorphism (nested-PCR-RFLP) assay to ...

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

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 ...

Evaluation of Nested PCR in Diagnosis of Typhoid Fever [PDF]

Journal of Clinical Microbiology, 2005
ABSTRACT In this study, nested PCR using H1-d primers, which is specific for Salmonella enterica serovar Typhi, was compared to blood culture and the single-tube Widal test. Results indicate that nested PCR can be used as a gold standard to determine the cutoff titer of the Widal ...

Single-tube nested PCR in the diagnosis of tuberculosis. [PDF]

Journal of Clinical Pathology, 1996
AIMS: To evaluate the usefulness of a single-tube nested polymerase chain reaction (PCR) assay in the diagnosis of tuberculosis in 1497 pulmonary and 536 extrapulmonary specimens. METHODS: A single-tube nested PCR, utilising two sets of primers with different melting temperatures (88 degrees C for external primers; 70 degrees C for internal primers) to

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 for the detection of Candidatus arthromitus in fish [PDF]

FEMS Microbiology Letters, 2010
Rainbow trout gastroenteritis has been related to the accumulation of segmented filamentous bacteria in the digestive tract of fish, which presents lethargy, reduced appetite and accumulation of mucoid faeces. Some authors associate the comparison of illness with the presence of viable filaments, which produce and release strings of endospores in the ...

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,

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 ...
