Abstract Background Japanese encephalitis virus is a mosquito-borne neurotropic flavivirus that causes acute viral in humans. Pigs are crucial amplifier host of JEV. Recently, increasing evidence has shown long non-coding RNAs (lncRNAs) play important roles infection. Methods JEV proliferation was evaluated after overexpression or knockdown lncRNA-SUSAJ1 using western blotting and reverse-trans...

BACKGROUND This study was designed to compare the detection rates of conventional tumor markers with two molecular diagnostic approaches on blood samples from patients with esophageal squamous cell cancer. MATERIALS AND METHODS Preoperative blood samples were obtained from 44 esophageal cancer patients and were subjected to CEA-specific reverse transcriptase-polymerase chain reaction (RT-PCR)...

A reverse transcriptase (RT)-nested-polymerase chain reaction (PCR) was standardised to detect bovine respiratory syncytial virus (BRSV), using a Brazilian isolate, in three experimentally infected calves. This followed initial tests in infected chicken embryo related (CER) cells. One animal had lesions, characterized by interstitial multifocal pneumonia, severe interstitial and subpleural emph...

During the outbreak, from 16 January 2002 to 3 March 2002, nasopharyngeal secretions obtained from 35 pediatric patients under 2 years of age and suffering from acute respiratory disease were tested by VIDAS respiratory syncytial virus (RSV) assay (an automated enzyme-linked fluorescent immunoassay) and reverse transcription- polymerase chain reaction (RT-PCR). RSV antigen was detected in 16 sp...

The objective of this study was to compare agar gel immunodiffusion test (AGID) and immunohistochemistry (IHC) with reverse transcriptase-polymerase chain reaction (RT-PCR) in terms of sensitivity and specificity for the detection of infectious bursal disease virus (IBDV). Thirty-five bursal samples collected from filed outbreak of IBD were evaluated by all 3 diagnostic tests. Sensitivity and s...

Severe acute respiratory syndrome (SARS) has caused a major epidemic worldwide. A novel coronavirus is deemed to be the causative agent. Early diagnosis can be made with reverse transcriptase-polymerase chain reaction (RT-PCR) of nasopharyngeal aspirate samples. We compared symptoms of 156 SARS-positive and 62 SARS-negative patients in Hong Kong; SARS was confirmed by RT-PCR. The RT-PCR-positiv...

A reverse transcription polymerase chain reaction (RT-PCR), based on the gene encoding the NS2 protein of African horsesickness virus (AHSV), was developed for rapid serogroup-specific detection of AHSV. The specificity of RT-PCR products was confirmed by Southern blot hybridization using a radioactively labelled cDNA probe specific for the NS2 gene. This RT-PCR could discriminate between all k...
