Enterovirus A71 (EV-A71) is an important human pathogen and 'prototype pathogen' for studies of other Enteroviruses of pandemic potential. Understanding the biology of EV-A71 would inform generalizable strategies for antiviral drug, vaccine, and monoclonal antibody development. Such studies are accelerated by robust reagents to evaluate efficacy. Here, we describe and evaluate a suite of synthetic reporter constructs to accelerate EV-A71 research and therapeutic discovery. These constructs include replicons and infectious clones carrying luminescent and fluorescent reporter proteins. Among the reporters we tested were shorter luminescent and de novo-designed synthetic fluorescent proteins, which enhance genetic stability, reduce reporter gene loss and improve the utility of these reporters. This toolbox provides free access to robust and flexible assays for EV-A71 infection and replication through public repositories, promoting and accelerating open scientific discovery for this understudied emerging pathogen.
