Comparison of the Real-time Nucleic Acid Sequence-based Amplification (RTi-NASBA) with Conventional NASBA, and Galactomannan Assay for the Diagnosis of Invasive Aspergillosis
We compared a real time-nucleic acid sequence-based amplification (RTi-NASBA) with conventional NASBA, galactomannan enzyme immunosorbent assay (GMEIA), and Mycology Study Group of the European Organization for Research and Treatment of Cancer (EORTC/MSG) criteria for the diagnosis of invasive aspergillosis (IA). From May 2004 to May 2005, blood samples (314 in total) were collected twice a wee...
متن کاملSensitivity and Specificity of Nucleic Acid Sequence-Based Amplification Method for Diagnosis of Cutaneous Leishmaniasis
Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...
متن کاملDevelopment and evaluation of nucleic acid sequence based amplification (NASBA) for diagnosis of enterovirus infections using the NucliSens Basic Kit.
BACKGROUND Molecular methods based on RNA amplification are needed for sensitive detection of enteroviruses in clinical samples. Many 'in house' methods based on reverse-transcribed PCR (RT-PCR) could be difficult to use in the routine diagnostic laboratory since they tend to be time-consuming, use reagents from many different suppliers and include non-routine procedures. OBJECTIVES The aim o...
متن کاملReal-Time Nucleic Acid Sequence-Based Amplification to Predict the Clinical Outcome of Invasive Aspergillosis
Monitoring the response to therapy for invasive aspergillosis (IA) is essential for the management of patients with hematologic diseases. We evaluated the correlation between the outcome of real-time nucleic acid sequence-based amplification (RTi-NASBA) for Aspergillus 18S rRNA and the clinical outcome of IA. A total of 157 serum samples from 29 patients with IA were tested for RTi-NASBA. The t...
متن کاملNASBA isothermal enzymatic in vitro nucleic acid amplification optimized for the diagnosis of HIV-1 infection.
Isothermal nucleic acid amplification of target RNA or DNA sequences is accomplished by the simultaneous enzymatic activity of AMV reverse transcriptase, T7 RNA polymerase and RNase H. Amplification factors of the nucleic acid sequence based amplification (NASBA) method range from 2 x 10(6) to 5 x 10(7) after 2.5 h incubation at 41 degrees C. During NASBA there is a major accumulation of specif...
