Protein priming of viral RNA synthesis plays an essential role in the replication of picornavirus RNA. Both poliovirus and coxsackievirus encode a small polypeptide, VPg, which serves as a primer for addition of the first nucleotide during synthesis of both positive and negative strands. This study examined the effects on the VPg uridylylation reaction of the RNA template sequence, the origin o...
BACKGROUND Enteroviruses (EVs) are significant human pathogens. Rapid and sensitive diagnostic techniques are desirable. OBJECTIVES To develop a quantitative single-tube real-time reverse transcription-polymerase chain reaction (RT-PCR) for human enterovirus ribonucleic acid (RNA) (QPCR), with protection against amplimer contamination. STUDY DESIGN The method was evaluated with serial dilut...
The interaction of coxsackievirus A13 with differentiating muscle cells, cultured from tissues of the fetal mouse, was studied. Cultures infected at that stage of myogenic differentiation characterized by the rapid formation of multinucleated myotubes produced maximum virus titers of over 10(7) plaque-forming units. Virus-induced cytopathic effect was characterized by a marked diminution in the...
WIN 54954 (5-[5-[2,6-dichloro-4-(4,5-dihydro-2-oxazolyl)phenoxy]pentyl]-3- methylisoxazole) is a new member of the class of broad-spectrum antipicornavirus compounds known to bind in a hydrophobic pocket within virion capsid protein VP1. In plaque reduction assays, WIN 54954 reduced plaque formation of 50 of 52 rhinovirus serotypes (MICs ranged from 0.007 to 2.2 micrograms/ml). A concentration ...
A sensitive reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for human enterovirus 71 (EV71) and Coxsackievirus A16 (CVA16) infection was further evaluated. The one step reaction was performed in a single tube at 65 ̊C for 45 min for EV71 and 35 min for CVA16. The detection limits of RT-LAMP assays for both EV71 and CVA16 were 0.1 of a 50% tissue culture infective dos...
