Judy Northill, Ian Mackay DOI:10.17504/protocols.io.bgz2jx8e Public Health Virology, Forensic and Scientific Services, Coronavirus Method Development Community A nested RT-PCR targeting the RdRp region of the sub-genus Sarbecovirus. The primers are modified from the pan-coronavirus RT-PCR published by Hu et al. 2017 to be more specific to SARS-CoV-2, though other coronaviruses may still be detected. Assay may be used in resource poor settings where real-time cyclers are not available.Sanger sequencing should be used to confirm SARS-CoV-2 where WGS is not available or where WGS fails due to poor quality sample.

Enterovirus (EV) A71 real-time RT-PCR (EV-A71-TM2018)
 
Resource Report

Ian Mackay, Judy Northill DOI:10.17504/protocols.io.xb3fiqn Public Health Virology, Forensic and Scientific Services This protocol aims to amplify enterovirus (EV) A71 viruses but not other viruses.This protocol was designed by us.The oligonucleotides target the 5'UTR noncoding region. This is a qualitative test for investigating EV-A71 infection of humans.The test has identified both historical EV-A71 strains and contemporary strains and has confirmed these using subgenomic sequencing of partial 5'UTR-VP2 and partial VP1 sequencing. Culture of the virus is not required as this assay is capable of detecting EV-A71 direct from extracted clinical samples.

Human Parechovirus A real-time RT-PCR ["Nix assay"; 2008-2015]
 
Resource Report

Ian Mackay DOI:10.17504/protocols.io.k2jcycn I and my team used this assay between 2008-2015; we dubbed it the "Nix assay". It targets the 5'UTR and employs quite degenerate oligos.In silico sequence alignments indicated the olignucleotides could theoretically detect aft least HPeV 1-7, 17 and 18.However during a period of assay comparison, another assay (see link below), the "Benschop assay" (J.Clin.Virol. 2008. 41(2):69-74), was found to produce more sigmoidal and higher curves and 1-5 cycle improvements to CT values when compared among the sample sampe extract set.
