Evaluation of real-time PCR versus PCR with liquid-phase hybridization for detection of enterovirus RNA in cerebrospinal fluid.

Enterovirus RNA in Cerebrospinal Fluid Liquid-Phase Hybridization for Detection of Evaluation of Real-Time PCR versus PCR with

Detection of enteroviruses and rhinoviruses in clinical specimens by PCR and liquid-phase hybridization.

A sensitive method based on PCR followed by liquid-phase hybridization for detection of enterovirus and rhinovirus RNAs in clinical specimens and cell culture supernatants is described. RNA was extracted from stool samples, throat swabs, nasopharyngeal aspirates, cerebrospinal fluid, urine, and plasma with a commercial phenol-guanidinium-chloroform reagent and purified on a polysulfone membrane...

Rapid detection of enterovirus RNA in cerebrospinal fluid specimens with a novel single-tube real-time reverse transcription-PCR assay.

A single-tube real-time reverse transcription-PCR (RT-PCR) assay for enterovirus detection in cerebrospinal fluid (CSF) was developed based on a fluorogenic probe and primers directed to highly conserved sequences in the 5' untranslated region of the enterovirus genome. Quantitative detection of enterovirus genome was demonstrated in a linear range spanning at least 5 logs. Endpoint titration e...

Human enteroviruses in cerebrospinal fluid of children with suspected aseptic meningitis: A study in northern Iran

Background: Enterovirus (EV) infections are one of the most common causes of aseptic meningitis in pediatrics. To diagnose EV meningitis, virus isolation in cell cultures is often time consuming and lacks sensitivity to be of clinical relevance. This makes the virus culture results difficult to interpret. The rapid detection of EVs in cerebrospinal fluid (CSF) by molecular diagnostic techniques...

Detection of human picornaviruses by multiplex reverse transcription-PCR and liquid hybridization.

A qualitative multiplex reverse transcription (RT)-PCR and liquid hybridization assay for the detection of human enteroviruses, rhinoviruses, parechoviruses, and Aichi virus was developed. Furthermore, a separate assay for the recognition of hepatitis A virus was established to complement the test pattern so that all human picornaviruses were covered. The amplicons, which represented the 5' unt...
