A combination of single-tube reverse transcription (RT)-PCR and nested PCR was used to identify spring viraemia of carp rhabdovirus (SVCV) in infected cell cultures and fish tissues. Two pairs of specific primers (external and internal) were selected from the glycoprotein gene sequence. A specific product of 470 bp was amplified from RNA derived from 34 SVCV isolates including the reference str...
This study was conducted to determine the presence of hepatitis A virus (HAV) in raw oysters (Crassostrea belcheri) using a virus concentration method and reverse transcription-nested polymerase chain reaction (RT-nested PCR). A total of 220 oyster samples were collected from oyster farms and local markets in Thailand. HAV was found in three oyster samples. Nested PCR products of HAV detected i...
Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...

: نتایج نشان داد که با استفاده از روش nested pcr قطعات bp236 و bp420 از آ.فومیگاتوس تکثیر می شود. با این روش، سرم 6 مورد از 30 بیمار bmt، نشان داد که دارای عفونت آسپرژیلوزی هستند. همچنین مطالعات با استفاده از پرایمرهای igsr و igsl نشان داد که در تفریق 6 بیمار آسپرژیلوزی از همان 30 بیمار bmt با الگوهای الکتروفورتیک متفاوت که برگرفته از منابع متفاوت آسپرژیلوس بوده است، موفق می باشد. نتیجه گیری:...
BACKGROUND AFRIMS longitudinal dengue surveillance in Thailand depends on the nested RT-PCR and the dengue IgM/IgG ELISA. OBJECTIVE To examine and improve the sensitivity of the nested RT-PCR using a panel of archived samples collected during dengue surveillance. STUDY DESIGN A retrospective analysis of 16,454 dengue IgM/IgG ELISA positive cases collected between 2000 and 2013 was done to i...
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 detect and type HPV based on the analysis of L1 gene. METHODS Analysis of published DNA sequence of mucosal HPV types to select sequences of new...
Leptospirosis is a worldwide sanitary problem. Its clinical signs resemble that of other diseases like Dengue and Flu, and it is difficult to distinguish between them. Currently available diagnostic methods shown low sensitivity and specificity. Efforts have been made to develop simpler, faster and more efficient diagnostic methods. The aim of this work was to evaluate and optimize a Nested-PCR...
