The RNA genomes of plus-strand RNA viruses have the ability to form secondary and higher-
order structures that contribute to their stability and to their participation in inter-and …

Internal ribosome entry site (IRES) elements were first identified about 20 years ago within
the 5′ untranslated region of picornavirus RNAs. They direct a cap-independent …

The genome sequences of three duck hepatitis virus type 1 (DHV-1) strains were
determined. Comparative sequence analyses showed that they possessed a typical …

Duck hepatitis virus type 1 (DHV-1) was previously classified as an enterovirus, based
primarily on observed morphology and physicochemical properties of the virion. The …

Picornaviridae are a large virus family causing widespread, often pathogenic infections in
humans and other mammals. Picornaviruses are genetically and antigenically highly …

2A is an oligopeptide sequence mediating a ribosome 'skip**'effect, producing an
apparent 'cleavage'of polyproteins. First identified and characterized in picornaviruses,'2A …

ABSTRACT The 5′ untranslated regions (UTRs) of the RNA genomes of Flaviviridae of the
Hepacivirus and Pestivirus genera contain internal ribosomal entry sites (IRESs) that are …

The family Picornaviridae contains important pathogens including, for example, hepatitis A
virus and foot-and-mouth disease virus. The genome of these viruses is a single messenger …

The molecular classification of the porcine enterovirus (PEV) groups II and III was
investigated. The sequence of the almost complete PEV-8 (group II) genome reveals that …

Investigations were carried out to identify the causative agent of acute diarrhea, respiratory
distress, and polioencephalomyelitis of pigs on a swine farm in Shanghai, China. Samples …
